Study Notes

Introduction to Transaction Processing Concepts

A transaction functions as a logical unit of database processing, encompassing one or more SQL statements such as read, write, update, or delete.
It transitions the database from one consistent state to another, ensuring integrity and consistency during operations.
Defined as an action or a series of related actions by a user or application, transactions access or modify database content.
The outcome of all SQL statements within a transaction can either be fully committed to the database or entirely rolled back if necessary.
Real-time changes made to the database are categorized as transactions, emphasizing their immediate impact on data integrity.
Common examples of transactions include ATM transactions, phone calls, academic registrations, billing, and hotel check-ins.

Transaction Processing System (TPS)

A Transaction Processing System is responsible for managing transactions and regulating their access to the Database Management System (DBMS).
The core component of a TPS is the TP monitor, which oversees transaction execution and ensures data consistency.
TPS typically comprises the TP monitor, one or more DBMS, and a set of user applications that interact with the database.
