Step 1: Understand what a DBMS is. A DBMS (Database Management System) is software that helps manage databases.
Step 2: Know what a transaction is. A transaction is a set of operations that are treated as a single unit.
Step 3: Learn why transactions are important. They help ensure that all operations within the transaction are completed successfully.
Step 4: Recognize the concept of data integrity. Data integrity means that the data in the database is accurate and consistent.
Step 5: Understand the 'all or nothing' principle. If one part of the transaction fails, the entire transaction fails, preventing partial updates.
Step 6: Conclude that the purpose of a transaction is to keep the database reliable and accurate by ensuring that related operations succeed or fail together.
