Study Notes
Transaction Processing Concepts
- A transaction is defined as a logical unit of database processing, encompassing one or more SQL statements (e.g., read-retrieval, write-insert, update, delete).
- Transactions transition the database from one consistent state to another, ensuring data integrity.
- It represents an action or series of actions performed by a user or application program that modifies the database's contents.
- Transaction outcomes can either be fully committed, meaning changes are applied to the database, or rolled back, where changes are undone.
- Real-time changes made to databases are classified as transactions.
- Common examples of transactions include ATM transactions, phone calls, academic registrations, billing processes, and hotel check-ins.
Transaction Processing System (TPS)
- A Transaction Processing System (TPS) is a specialized system designed to manage and control database transactions.
- The core component of TPS is the TP monitor, which oversees transaction access to the Database Management System (DBMS).
- A TPS generally comprises the TP monitor, one or multiple DBMS, and an associated set of resources.
