2. •What is a TPS?
•Characteristics of TPS
•a Transaction Processing Model
•Batch Processing vs. On-line Processing
•TPS Applications
Learning Objectives

3. •TPS is a type of IS that collect, store, modify,
and retrieve the transactions of an
organization.
•TPS designed to process routine business
transactions
•seeks time- and cost-efficiency by
automating repetitive operations in large
volumes
•Directly support Business Operations.
What is a TPS?

4. What is a TPS?
•Must be designed in conjunction with the
organization’s procedures.
•Main information processes: collecting and
storage.
•e.g,, airline reservation systems, bank’s
account processing systems, and student
registration system.

5. Value of TPS
•Efficiency
–Paperless Transactions
–Reduce manual data entry (errors)
–Speed up transaction process
–Elimination of redundant steps

6. The Major Characteristics of TPS
•Large amounts of data are processed.
•The sources of data are mostly internal, and the output is intended
mainly for an internal audience.
•The TPS processes information on a regular basis: daily, weekly,
monthly, etc.
•Large storage (database) capacity is required.
•High processing speed is needed due to the high volume.
•TPS basically monitors and collects past data.
•Input and output data are structured (i.e., standardized).
•Low computation complexity is usually evident in TPS.
•A high level of accuracy, data integrity, and security is needed.
•High reliability is required.

8. Batch vs. On-Line
Batch Processing
•transaction data are
accumulated
•processed periodically
•used to be necessary
because of synchronization
problems
On-Line Processing
•also called online
•immediately processed
•Syncronization issues
•What if two people order
the same product at the
same extact time, but
there is only one
product
left?
