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.
