PREFACE
The advantage of doing one’s praising for oneself is that one can lay it on so thick
and exactly in the right places.
—Samuel Butler
Database management systems are now an indisp ensable to ol for managing
information, and a course on the principles and practice of database systems
is now an integral part of computer science curricula. This b o ok covers the
fundamentals of mo dern database management systems, in particular relational
database systems.
We have attempted to present the material in a clear, simple style. A quantita-
tive approach is used throughout with many detailed examples. An extensive
set of exercises (for which solutions are available online to instructors) accom-
panies each chapter and reinforces students’ ability to apply the concepts to
real problems.
The b o ok can b e used with the accompanying software and programming as-
signments in two distinct kinds of intro ductory courses:
1.Applications Emphasis:A course that covers the principles of database
systems, and emphasizes how they are used in developing data-intensive ap-
plications. Two new chapters on application development (one on database-
backed applications, and one on Java and Internet application architec-
tures) have b een added to the third edition, and the entire b o ok has b een
extensively revised and reorganized to supp ort such a course. A running
case-study and extensive online materials (e.g., co de for SQL queries and
Java applications, online databases and solutions) make it easy to teach a
hands-on application-centric course.
2.Systems Emphasis:A course that has a strong systems emphasis and
assumes that students have go o d programming skills in C and C++. In
this case the accompanying Minibase software can b e used as the basis
for pro jects in which students are asked to implement various parts of a
relational DBMS. Several central mo dules in the pro ject software (e.g.,
heap files, buffer manager, B+ trees, hash indexes, various join metho ds)

Preface xxv
are describ ed in sufficient detail in the text to enable students to implement
them, given the (C++) class interfaces.
Many instructors will no doubt teach a course that falls b etween these two
extremes. The restructuring in the third edition offers a very mo dular orga-
nization that facilitates such hybrid courses. The also b o ok contains enough
material to supp ort advanced courses in a two-course sequence.
Organization of the Third Edition
The b o ok is organized into six main parts plus a collection of advanced topics, as
shown in Figure 0.1. The Foundations chapters intro duce database systems, the
(1) Foundations Both
(2) Application Development Applications emphasis
(3) Storage and Indexing Systems emphasis
(4) Query Evaluation Systems emphasis
(5) Transaction Management Systems emphasis
(6) Database Design and Tuning Applications emphasis
(7) Additional Topics Both
Figure 0.1Organization of Parts in the Third Edition
ER mo del and the relational mo del. They explain how databases are created
and used, and cover the basics of database design and querying, including an
in-depth treatment of SQL queries. While an instructor can omit some of this
material at their discretion (e.g., relational calculus, some sections on the ER
mo del or SQL queries), this material is relevant to every student of database
systems, and we recommend that it b e covered in as much detail as p ossible.
Each of the remaining five main parts has either an application or a systems
emphasis. Each of the three Systems parts has an overview chapter, designed to
provide a self-contained treatment, e.g., Chapter 8 is an overview of storage and
indexing. The overview chapters can b e used to provide stand-alone coverage
of the topic, or as the first chapter in a more detailed treatment. Thus, in an
application-oriented course, Chapter 8 might b e the only material covered on
file organizations and indexing, whereas in a systems-oriented course it would b e
supplemented by a selection from Chapters 9 through 11. The Database Design
and Tuning part contains a discussion of p erformance tuning and designing for
secure access. These application topics are b est covered after giving students
a go o d grasp of database system architecture, and are therefore placed later in
the chapter sequence.

xxvi Database Management Systems
Suggested Course Outlines
The b o ok can b e used in two kinds of intro ductory database courses, one with
an applications emphasis and one with a systems emphasis.
Theintroductory applications-oriented coursecould cover the Foundations chap-
ters, then the Application Development chapters, followed by the overview sys-
tems chapters, and conclude with the Database Design and Tuning material.
Chapter dep endencies have b een kept to a minimum, enabling instructors to
easily fine tune what material to include. The Foundations material, Part I,
should b e covered first, and within Parts I I I, IV, and V, the overview chapters
should b e covered first. The only remaining dep endencies b etween chapters
in Parts I to VI are shown as arrows in Figure 0.2. The chapters in Part I
should b e covered in sequence. However, the coverage of algebra and calculus
can b e skipp ed in order to get to SQL queries so oner (although we b elieve this
material is imp ortant and recommend that it should b e covered b efore SQL).
Theintroductory systems-oriented coursewould cover the Foundations chap-
ters and a selection of Applications and Systems chapters. An imp ortant p oint
for systems-oriented courses is that the timing of programming pro jects (e.g.,
using Minibase) makes it desirable to cover some systems topics early. Chap-
ter dep endencies have b een carefully limited to allow the Systems chapters to
b e covered as so on as Chapters 1 and 3 have b een covered. The remaining
Foundations chapters and Applications chapters can b e covered subsequently.
The b o ok also has ample material to supp ort a multi-course sequence. Obvi-
ously, cho osing an applications or systems emphasis in the intro ductory course
results in dropping certain material from the course; the material in the b o ok
supp orts a comprehensive two-course sequence that covers b oth applications
and systems asp ects. The Additional Topics range over a broad set of issues,
and can b e used as the core material for an advanced course, supplemented
with further readings.
Supplementary Material
This b o ok comes with extensive online supplements:
Online Chapter:To make space for new material such as application
development, information retrieval, and XML, we’ve moved the coverage
of QBE to an online chapter. Students can freely download the chapter
from the b o ok’s web site, and solutions to exercises from this chapter are
included in solutions manual.

Lecture Slides:Lecture slides are freely available for all chapters in
Postscript, and PDF formats. Course instructors can also obtain these
slides in Microsoft Powerp oint format, and can adapt them to their teach-
ing needs. Instructors also have access to all figures used in the b o ok (in
xfig format), and can use them to mo dify the slides.

xxviii Database Management Systems
Solutions to Chapter Exercises:The b o ok has an unusually extensive
set of in-depth exercises. Students can obtain solutions to o dd-numb ered
chapter exercises and a set of lecture slides for each chapter through the
Web in Postscript and Adob e PDF formats. Course instructors can obtain
solutions to all exercises.
Software:The b o ok comes with two kinds of software. First, we have
Minibase, a small relational DBMS intended for use in systems-oriented
courses. Minibase comes with sample assignments and solutions, as de-
scrib ed in App endix 30. Access is restricted to course instructors. Second,
we offer co de for all SQL and Java application development exercises in
the b o ok, together with scripts to create sample databases, and scripts for
setting up several commercial DBMSs. Students can only access solution
co de for o dd-numb ered exercises, whereas instructors have access to all
solutions.
Instructor’s Manual:The b o ok comes with an online manual that of-
fers instructors comments on the material in each chapter. It provides a
summary of each chapter and identifies choices for material to emphasize
or omit. The manual also discusses the on-line supp orting material for
that chapter and offers numerous suggestions for hands-on exercises and
pro jects. Finally, it includes samples of examination pap ers from courses
taught by the authors using the b o ok. It is restricted to course instructors.

Acknowledgments
This b o ok grew out of lecture notes for CS564, the intro ductory (senior/graduate
level) database course at UW-Madison. David DeWitt develop ed this course
and the Minirel pro ject, in which students wrote several well-chosen parts of
a relational DBMS. My thinking ab out this material was shap ed by teaching
CS564, and Minirel was the inspiration for Minibase, which is more compre-
hensive (e.g., it has a query optimizer and includes visualization software) but

Preface xxix
tries to retain the spirit of Minirel. Mike Carey and I jointly designed much of
Minibase. My lecture notes (and in turn this b o ok) were influenced by Mike’s
lecture notes and by Yannis Ioannidis’s lecture slides.
Jo e Hellerstein used the b eta edition of the b o ok at Berkeley and provided
invaluable feedback, assistance on slides, and hilarious quotes. Writing the
chapter on ob ject-database systems with Jo e was a lot of fun.
C. Mohan provided invaluable assistance, patiently answering a numb er of ques-
tions ab out implementation techniques used in various commercial systems, in
particular indexing, concurrency control, and recovery algorithms. Moshe Zlo of
answered numerous questions ab out QBE semantics and commercial systems
based on QBE. Ron Fagin, Krishna Kulkarni, Len Shapiro, Jim Melton, Dennis
Shasha, and Dirk Van Gucht reviewed the b o ok and provided detailed feedback,
greatly improving the content and presentation. Michael Goldweb er at Beloit
College, Matthew Haines at Wyoming, Michael Kifer at SUNY StonyBro ok,
Jeff Naughton at Wisconsin, Praveen Seshadri at Cornell, and Stan Zdonik at
Brown also used the b eta edition in their database courses and offered feedback
and bug rep orts. In particular, Michael Kifer p ointed out an error in the (old)
algorithm for computing a minimal cover and suggested covering some SQL
features in Chapter 2 to improve mo dularity. Gio Wiederhold’s bibliography,
converted to Latex format by S. Sudarshan, and Michael Ley’s online bibliogra-
phy on databases and logic programming were a great help while compiling the
chapter bibliographies. Shaun Flisakowski and Uri Shaft help ed me frequently
in my never-ending battles with Latex.
I owe a sp ecial thanks to the many, many students who have contributed to
the Minibase software. Emmanuel Ackaouy, Jim Pruyne, Lee Schumacher, and
Michael Lee worked with me when I develop ed the first version of Minibase
(much of which was subsequently discarded, but which influenced the next
version). Emmanuel Ackaouy and Bryan So were my TAs when I taught CS564
using this version and went well b eyond the limits of a TAship in their efforts
to refine the pro ject. Paul Aoki struggled with a version of Minibase and
offered lots of useful comments as a TA at Berkeley. An entire class of CS764
students (our graduate database course) develop ed much of the current version
of Minibase in a large class pro ject that was led and co ordinated by Mike Carey
and me. Amit Shukla and Michael Lee were my TAs when I first taught CS564
using this version of Minibase and develop ed the software further.
Several students worked with me on indep endent pro jects, over a long p erio d
of time, to develop Minibase comp onents. These include visualization packages
for the buffer manager and B+ trees (Huseyin Bektas, Harry Stavrop oulos, and
Weiqing Huang); a query optimizer and visualizer (Stephen Harris, Michael Lee,
and Donko Donjerkovic); an ER diagram to ol based on the Op ossum schema

xxx Database Management Systems
editor (Eb en Hab er); and a GUI-based to ol for normalization (Andrew Pro ck
and Andy Therb er). In addition, Bill Kimmel worked to integrate and fix a
large b o dy of co de (storage manager, buffer manager, files and access metho ds,
relational op erators, and the query plan executor) pro duced by the CS764 class
pro ject. Ranjani Ramamurty considerably extended Bill’s work on cleaning up
and integrating the various mo dules. Luke Blanshard, Uri Shaft, and Shaun
Flisakowski worked on putting together the release version of the co de and
develop ed test suites and exercises based on the Minibase software. Krishna
Kunchithapadam tested the optimizer and develop ed part of the Minibase GUI.
Clearly, the Minibase software would not exist without the contributions of a
great many talented p eople. With this software available freely in the public
domain, I hop e that more instructors will b e able to teach a systems-oriented
database course with a blend of implementation and exp erimentation to com-
plement the lecture material.
I’d like to thank the many students who help ed in developing and checking
the solutions to the exercises and provided useful feedback on draft versions of

Charlie Fischer, Avi Silb erschatz, and Jeff Ullman gave me invaluable advice
on working with a publisher. My editors at McGraw-Hill, Betsy Jones and Eric
Munson, obtained extensive reviews and guided this b o ok in its early stages.
Emily Gray and Brad Kosirog were there whenever problems cropp ed up. At
Wisconsin, Ginny Werner really help ed me to stay on top of things.
Finally, this b o ok was a thief of time, and in many ways it was harder on my
family than on me. My sons expressed themselves forthrightly. From my (then)
five-year-old, Ketan: “Dad, stop working on that silly b o ok. You don’t have
any time forme.” Two-year-old Vivek: “You workingboook? No no no come
play basketball me!” All the seasons of their discontent were visited up on my
wife, and Apu nonetheless cheerfully kept the family going in its usual chaotic,
happy way all the many evenings and weekends I was wrapp ed up in this b o ok.
(Not to mention the days when I was wrapp ed up in b eing a faculty memb er!)
As in all things, I can trace my parents’ hand in much of this; my father,
with his love of learning, and my mother, with her love of us, shap ed me. My
brother Kartik’s contributions to this b o ok consisted chiefly of phone calls in
which he kept me from working, but if I don’t acknowledge him, he’s liable to

Whitaker iterated many times on the cover and end-sheet design.
On a p ersonal note for Raghu, Ketan, following the canny example of the
camel that shared a tent, observed that “it is only fair” that Raghu dedicate
this edition solely to him and Vivek, since “mommy already had it dedicated
only to her.” Despite this blatant attempt to hog the limelight, enthusiastically
supp orted by Vivek and viewed with the indulgent affection of a doting father,
this b o ok is also dedicated to Apu, for b eing there through it all.
For Johannes, this revision would not have made it without Keiko’s supp ort

The area of database management systems is a micro cosm of computer sci-
ence in general. The issues addressed and the techniques used span a wide
sp ectrum, including languages, ob ject-orientation and other programming
paradigms, compilation, op erating systems, concurrent programming, data
structures, algorithms, theory, parallel and distributed systems, user inter-
faces, exp ert systems and artificial intelligence, statistical techniques, and
dynamic programming. We cannot go into all these asp ects of database
management in one b o ok, but we hop e to give the reader a sense of the
excitement in this rich and vibrant discipline.
managing the data and extracting useful information in a timely fashion. Oth-
erwise, data can b ecome a liability, with the cost of acquiring it and managing
it far exceeding the value derived from it.
Adatabaseis a collection of data, typically describing the activities of one or
more related organizations. For example, a university database might contain
information ab out the following:
Entitiessuch as students, faculty, courses, and classro oms.
Relationshipsb etween entities, such as students’ enrollment in courses,
faculty teaching courses, and the use of ro oms for courses.
Adatabase management system, orDBMS, is software designed to assist
in maintaining and utilizing large collections of data. The need for such systems,
as well as their use, is growing rapidly. The alternative to using a DBMS is
to store the data in files and write application-sp ecific co de to manage it. The
use of a DBMS has several imp ortant advantages, as we will see in Section 1.4.
1.1 MANAGING DATA
The goal of this b o ok is to present an in-depth intro duction to database man-
agement systems, with an emphasis on how todesigna database andusea
DBMS effectively. Not surprisingly, many decisions ab out how to use a DBMS
for a given application dep end on what capabilities the DBMS supp orts effi-
ciently. Therefore, to use a DBMS well, it is necessary to also understand how
a DBMSworks.
Many kinds of database management systems are in use, but this b o ok concen-
trates onrelational database systems (RDBMSs) , which are by far the
dominant typ e of DBMS to day. The following questions are addressed in the
core chapters of this b o ok:

Overview of Database Systems 5
1.Database Design and Application Development: How can a user
describ e a real-world enterprise (e.g., a university) in terms of the data
stored in a DBMS? What factors must b e considered in deciding how to
organize the stored data? How can we develop applications that rely up on
a DBMS? (Chapters 2, 3, 6, 7, 19, 20, and 21.)
2.Data Analysis:How can a user answer questions ab out the enterprise by
p osing queries over the data in the DBMS? (Chapters 4 and 5.)
1
3.Concurrency and Robustness:How do es a DBMS allow many users to
access data concurrently, and how do es it protect the data in the event of
system failures? (Chapters 16, 17, and 18.)
4.Efficiency and Scalability:How do es a DBMS store large datasets and
answer questions against this data efficiently? (Chapters 8, 9, 10, 11, 12,
13, 14, and 15.)
Later chapters cover imp ortant and rapidly evolving topics, such as parallel and
distributed database management, data warehousing and complex queries for
decision supp ort, data mining, databases and information retrieval, XML rep os-
itories, ob ject databases, spatial data management, and rule-oriented DBMS
extensions.
In the rest of this chapter, we intro duce these issues. In Section 1.2, we b e-
gin with a brief history of the field and a discussion of the role of database
management in mo dern information systems. We then identify the b enefits of
storing data in a DBMS instead of a file system in Section 1.3, and discuss
the advantages of using a DBMS to manage data in Section 1.4. In Section
1.5, we consider how information ab out an enterprise should b e organized and
stored in a DBMS. A user probably thinks ab out this information in high-level
terms that corresp ond to the entities in the organization and their relation-
ships, whereas the DBMS ultimately stores data in the form of (many, many)
bits. The gap b etween how users think of their data and how the data is ul-
timately stored is bridged through severallevels of abstractionsupp orted by
the DBMS. Intuitively, a user can b egin by describing the data in fairly high-
level terms, then refine this description by considering additional storage and
representation details as needed.
In Section 1.6, we consider how users can retrieve data stored in a DBMS and
the need for techniques to efficiently compute answers to questions involving
such data. In Section 1.7, we provide an overview of how a DBMS supp orts
concurrent access to data by several users and how it protects the data in the
event of system failures.

We then briefly describ e the internal structure of a DBMS in Section 1.8, and
mention various groups of p eople asso ciated with the development and use of
a DBMS in Section 1.9.
1.2 A HISTORICAL PERSPECTIVE
From the earliest days of computers, storing and manipulating data have b een a
ma jor application fo cus. The first general-purp ose DBMS, designed by Charles
Bachman at General Electric in the early 1960s, was called the Integrated Data
Store. It formed the basis for thenetwork data model, which was standardized
by the Conference on Data Systems Languages (CODASYL) and strongly in-
fluenced database systems through the 1960s. Bachman was the first recipient
of ACM’s Turing Award (the computer science equivalent of a Nob el Prize) for
work in the database area; he received the award in 1973.
In the late 1960s, IBM develop ed the Information Management System (IMS)
DBMS, used even to day in many ma jor installations. IMS formed the basis for
an alternative data representation framework called thehierarchical data model.
The SABRE system for making airline reservations was jointly develop ed by
American Airlines and IBM around the same time, and it allowed several p eople
to access the same data through a computer network. Interestingly, to day the
same SABRE system is used to p ower p opular Web-based travel services such
as Travelo city.
In 1970, Edgar Co dd, at IBM’s San Jose Research Lab oratory, prop osed a new
data representation framework called therelational data model. This proved to
b e a watershed in the development of database systems: It sparked the rapid
development of several DBMSs based on the relational mo del, along with a rich
b o dy of theoretical results that placed the field on a firm foundation. Co dd
won the 1981 Turing Award for his seminal work. Database systems matured
as an academic discipline, and the p opularity of relational DBMSs changed the
commercial landscap e. Their b enefits were widely recognized, and the use of
DBMSs for managing corp orate data b ecame standard practice.
In the 1980s, the relational mo del consolidated its p osition as the dominant
DBMS paradigm, and database systems continued to gain widespread use. The
SQL query language for relational databases, develop ed as part of IBM’s Sys-
tem R pro ject, is now the standard query language. SQL was standardized
in the late 1980s, and the current standard, SQL:1999, was adopted by the
American National Standards Institute (ANSI) and International Organization
for Standardization (ISO). Arguably, the most widely used form of concurrent
programming is the concurrent execution of database programs (calledtrans-
actions). Users write programs as if they are to b e run by themselves, and

Overview of Database Systems 7
the resp onsibility for running them concurrently is given to the DBMS. James
Gray won the 1999 Turing award for his contributions to database transaction
management.
In the late 1980s and the 1990s, advances were made in many areas of database
systems. Considerable research was carried out into more p owerful query lan-
guages and richer data mo dels, with emphasis placed on supp orting complex
analysis of data from all parts of an enterprise. Several vendors (e.g., IBM’s
DB2, Oracle 8, Informix
2
UDS) extended their systems with the ability to store
new data typ es such as images and text, and to ask more complex queries. Sp e-
cialized systems have b een develop ed by numerous vendors for creatingdata
warehouses, consolidating data from several databases, and for carrying out
sp ecialized analysis.
An interesting phenomenon is the emergence of severalenterprise resource
planning (ERP)andmanagement resource planning (MRP) packages,
which add a substantial layer of application-oriented features on top of a DBMS.
Widely used packages include systems from Baan, Oracle, PeopleSoft, SAP,
and Sieb el. These packages identify a set of common tasks (e.g., inventory
management, human resources planning, financial analysis) encountered by a
large numb er of organizations and provide a general application layer to carry
out these tasks. The data is stored in a relational DBMS and the application
layer can b e customized to different companies, leading to lower overall costs
for the companies, compared to the cost of building the application layer from
scratch.
Most significant, p erhaps, DBMSs have entered the Internet Age. While the
first generation of websites stored their data exclusively in op erating systems
files, the use of a DBMS to store data accessed through a Web browser is
b ecoming widespread. Queries are generated through Web-accessible forms
and answers are formatted using a markup language such as HTML to b e
easily displayed in a browser. All the database vendors are adding features to
their DBMS aimed at making it more suitable for deployment over the Internet.
Database management continues to gain imp ortance as more and more data is
brought online and made ever more accessible through computer networking.
To day the field is b eing driven by exciting visions such as multimedia databases,
interactive video, streaming data, digital libraries, a host of scientific pro jects
such as the human genome mapping effort and NASA’s Earth Observation Sys-
tem pro ject, and the desire of companies to consolidate their decision-making
pro cesses andminetheir data rep ositories for useful information ab out their
businesses. Commercially, database management systems represent one of the

largest and most vigorous market segments. Thus the study of database sys-
tems could prove to b e richly rewarding in more ways than one!
1.3 FILE SYSTEMS VERSUS A DBMS
To understand the need for a DBMS, let us consider a motivating scenario: A
company has a large collection (say, 500 GB
3
) of data on employees, depart-
ments, pro ducts, sales, and so on. This data is accessed concurrently by several
employees. Questions ab out the data must b e answered quickly, changes made
to the data by different users must b e applied consistently, and access to certain
parts of the data (e.g., salaries) must b e restricted.
We can try to manage the data by storing it in op erating system files. This
approach has many drawbacks, including the following:
We probably do not have 500 GB of main memory to hold all the data.
We must therefore store data in a storage device such as a disk or tap e and
bring relevant parts into main memory for pro cessing as needed.
Even if we have 500 GB of main memory, on computer systems with 32-bit
addressing, we cannot refer directly to more than ab out 4 GB of data. We
have to program some metho d of identifying all data items.
We have to write sp ecial programs to answer each question a user may want
to ask ab out the data. These programs are likely to b e complex b ecause
of the large volume of data to b e searched.
We must protect the data from inconsistent changes made by different users
accessing the data concurrently. If applications must address the details of
such concurrent access, this adds greatly to their complexity.
We must ensure that data is restored to a consistent state if the system
crashes while changes are b eing made.
Op erating systems provide only a password mechanism for security. This is
not sufficiently flexible to enforce security p olicies in which different users
have p ermission to access different subsets of the data.
A DBMS is a piece of software designed to make the preceding tasks easier. By
storing data in a DBMS rather than as a collection of op erating system files,
we can use the DBMS’s features to manage the data in a robust and efficient
manner. As the volume of data and the numb er of users grow
— hundreds of
gigabytes of data and thousands of users are common in current corp orate
databases
— DBMS supp ort b ecomes indisp ensable.

Overview of Database Systems 9
1.4 ADVANTAGES OF A DBMS
Using a DBMS to manage data has many advantages:
Data Indep endence:Application programs should not, ideally, b e ex-
p osed to details of data representation and storage. The DBMS provides
an abstract view of the data that hides such details.
Efficient Data Access:A DBMS utilizes a variety of sophisticated tech-
niques to store and retrieve data efficiently. This feature is esp ecially im-
p ortant if the data is stored on external storage devices.
Data Integrity and Security:If data is always accessed through the
DBMS, the DBMS can enforce integrity constraints. For example, b efore
inserting salary information for an employee, the DBMS can check that
the department budget is not exceeded. Also, it can enforceaccess controls
that govern what data is visible to different classes of users.
Data Administration:When several users share the data, centralizing
the administration of data can offer significant improvements. Exp erienced
professionals who understand the nature of the data b eing managed, and
how different groups of users use it, can b e resp onsible for organizing the
data representation to minimize redundancy and for fine-tuning the storage
of the data to make retrieval efficient.
Concurrent Access and Crash Recovery: A DBMS schedules concur-
rent accesses to the data in such a manner that users can think of the data
as b eing accessed by only one user at a time. Further, the DBMS protects
users from the effects of system failures.
Reduced Application Development Time: Clearly, the DBMS sup-
p orts imp ortant functions that are common to many applications accessing
data in the DBMS. This, in conjunction with the high-level interface to the
data, facilitates quick application development. DBMS applications are
also likely to b e more robust than similar stand-alone applications b ecause
many imp ortant tasks are handled by the DBMS (and do not have to b e
debugged and tested in the application).
Given all these advantages, is there ever a reasonnotto use a DBMS? Some-
times, yes. A DBMS is a complex piece of software, optimized for certain kinds
of workloads (e.g., answering complex queries or handling many concurrent
requests), and its p erformance may not b e adequate for certain sp ecialized ap-
plications. Examples include applications with tight real-time constraints or
just a few well-defined critical op erations for which efficient custom co de must
b e written. Another reason for not using a DBMS is that an application may
need to manipulate the data in ways not supp orted by the query language. In

10 Chapter 1
such a situation, the abstract view of the data presented by the DBMS do es
not match the application’s needs and actually gets in the way. As an exam-
ple, relational databases do not supp ort flexible analysis of text data (although
vendors are now extending their pro ducts in this direction).
If sp ecialized p erformance or data manipulation requirements are central to an
application, the application may cho ose not to use a DBMS, esp ecially if the
added b enefits of a DBMS (e.g., flexible querying, security, concurrent access,
and crash recovery) are not required. In most situations calling for large-scale
data management, however, DBMSs have b ecome an indisp ensable to ol.
1.5 DESCRIBING AND STORING DATA IN A DBMS
The user of a DBMS is ultimately concerned with some real-world enterprise,
and the data to b e stored describ es various asp ects of this enterprise. For
example, there are students, faculty, and courses in a university, and the data
in a university database describ es these entities and their relationships.
Adata mo delis a collection of high-level data description constructs that hide
many low-level storage details. A DBMS allows a user to define the data to b e
stored in terms of a data mo del. Most database management systems to day
are based on therelational data mo del, which we fo cus on in this b o ok.
While the data mo del of the DBMS hides many details, it is nonetheless closer
to how the DBMS stores data than to how a user thinks ab out the underlying
enterprise. Asemantic data mo delis a more abstract, high-level data mo del
that makes it easier for a user to come up with a go o d initial description of
the data in an enterprise. These mo dels contain a wide variety of constructs
that help describ e a real application scenario. A DBMS is not intended to
supp ort all these constructs directly; it is typically built around a data mo del
with just a few basic constructs, such as the relational mo del. A database
design in terms of a semantic mo del serves as a useful starting p oint and is
subsequently translated into a database design in terms of the data mo del the
DBMS actually supp orts.
A widely used semantic data mo del called the entity-relationship (ER) mo del
allows us to pictorially denote entities and the relationships among them. We
cover the ER mo del in Chapter 2.

Overview of Database Systems 11
An Example of Po or Design:The relational schema for Students il-
lustrates a p o or design choice; you shouldnevercreate a field such asage,
whose value is constantly changing. A b etter choice would b eDOB(for
date of birth); age can b e computed from this. We continue to useagein
our examples, however, b ecause it makes them easier to read.
1.5.1 The Relational Model
In this section we provide a brief intro duction to the relational mo del. The
central data description construct in this mo del is arelation, which can b e
thought of as a set ofrecords.
A description of data in terms of a data mo del is called aschema. In the
relational mo del, the schema for a relation sp ecifies its name, the name of each
field(orattributeorcolumn), and the typ e of each field. As an example,
student information in a university database may b e stored in a relation with
the following schema:
Students(sid:string,name:string,login:string,
age:integer,gpa:real)
The preceding schema says that each record in the Students relation has five
fields, with field names and typ es as indicated. An example instance of the
Students relation app ears in Figure 1.1.

53831 Madayan madayan@music 11 1.8
53832 Guldu guldu@music 12 2.0
Figure 1.1An Instance of the Students Relation
Each row in the Students relation is a record that describ es a student. The
description is not complete—for example, the student’s height is not included—
but is presumably adequate for the intended applications in the university
database. Every row follows the schema of the Students relation. The schema
can therefore b e regarded as a template for describing a student.
We can make the description of a collection of students more precise by sp ecify-
ingintegrity constraints, which are conditions that the records in a relation

12 Chapter 1
must satisfy. For example, we could sp ecify that every student has a unique
sidvalue. Observe that we cannot capture this information by simply adding
another field to the Students schema. Thus, the ability to sp ecify uniqueness
of the values in a field increases the accuracy with which we can describ e our
data. The expressiveness of the constructs available for sp ecifying integrity
constraints is an imp ortant asp ect of a data mo del.
Other Data Models
In addition to the relational data mo del (which is used in numerous systems,
including IBM’s DB2, Informix, Oracle, Sybase, Microsoft’s Access, FoxBase,
Paradox, Tandem, and Teradata), other imp ortant data mo dels include the
hierarchical mo del (e.g., used in IBM’s IMS DBMS), the network mo del (e.g.,
used in IDS and IDMS), the ob ject-oriented mo del (e.g., used in Ob jectstore
and Versant), and the ob ject-relational mo del (e.g., used in DBMS pro ducts
from IBM, Informix, Ob jectStore, Oracle, Versant, and others). While many
databases use the hierarchical and network mo dels and systems based on the
ob ject-oriented and ob ject-relational mo dels are gaining acceptance in the mar-
ketplace, the dominant mo del to day is the relational mo del.
In this b o ok, we fo cus on the relational mo del b ecause of its wide use and im-
p ortance. Indeed, the ob ject-relational mo del, which is gaining in p opularity, is
an effort to combine the b est features of the relational and ob ject-oriented mo d-
els, and a go o d grasp of the relational mo del is necessary to understand ob ject-
relational concepts. (We discuss the ob ject-oriented and ob ject-relational mo d-
els in Chapter 23.)
1.5.2 Levels of Abstraction in a DBMS
The data in a DBMS is describ ed at three levels of abstraction, as illustrated
in Figure 1.2. The database description consists of a schema at each of these
three levels of abstraction: theconceptual,physical, andexternal.
Adata definition language(DDL) is used to define the external and concep-
tual schemas. We discuss the DDL facilities of the most widely used database
language, SQL, in Chapter 3. All DBMS vendors also supp ort SQL commands
to describ e asp ects of the physical schema, but these commands are not part of
the SQL language standard. Information ab out the conceptual, external, and
physical schemas is stored in thesystem catalogs(Section 12.1). We discuss
the three levels of abstraction in the rest of this section.
