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.
