2. ACID Properties in DBMS with Examples John Doe Student

3. Introduction to ACID Properties 1 Concurrent Transactions ACID properties ensure that concurrent transactions do not interfere with each other, maintaining data integrity. 2 Data Recovery In the event of a failure, ACID properties allow for transactions to be rolled back, ensuring data recovery and consistency. 3 Maintain Accuracy By ensuring isolation and durability, ACID properties maintain the accuracy of data during transactions in a database. 4 Real-World Applications ACID properties are critical in banking transactions to ensure money transfer accuracy and consistency over distributed systems.

4. Importance of ACID in DBMS ACID ensures reliable transactions in banking applications where multiple operations, such as transferring funds, must either complete entirely or not at all. This isolation prevents conflicting updates, safeguarding data integrity, ensuring funds are neither lost nor erroneously duplicated.

5. Isolation Levels and Their Implications Read Uncommitted Allows reading uncommitted changes from transactions. 1 Read Committed Prevents reading of uncommitted data from transactions. 2 Repeatable Read Ensures consistent reads within the same transaction. 3 Serializable Provides strict isolation, ensuring complete transaction safety. 4 Snapshot Isolation Creates a snapshot for transactions to avoid conflicts. 5 Phantom Read Occurs when new rows match a previous query. 6 Concurrency Control Manages simultaneous transactions to ensure integrity. 7

6. Durability: Definition and Significance 1 Data Integrity Ensures data remains accurate even after failures. 2 Transaction Log Records all changes for recovery and rollback purposes. 3 Backup Strategies Regular backups are essential for data restoration. 4 System Redundancy Additional systems prevent data loss in case of failures. 5 Error Handling Detects and corrects issues to maintain data reliability. 6 User Trust Users rely on durability for consistent data availability.

7. Instructions to Change Color of Shapes Some shapes in this deck need to be ungrouped to change colors Step 1: Select the shape, and right click on it Step 2: Select Group -> Ungroup. Step 3: Once ungrouped, you will be able to change colors using the “Format Shape” option
