Description: The transaction state refers to the current state of a transaction in a database. In the context of databases, a transaction is a unit of work that is either fully executed or not executed at all, ensuring data integrity. The state of a transaction can be one of several: ‘initiated’, ‘in progress’, ‘completed’, or ‘aborted’. Each of these states reflects the progress of the transaction and its impact on the database. For example, when a transaction is initiated, a context is established for the operations that will be performed. During its execution, the database management system (DBMS) keeps track of the state, ensuring that all operations are carried out correctly. If an error occurs, the transaction can be rolled back to its initial state, known as ‘rollback’. This mechanism is fundamental to maintaining data consistency and integrity, especially in systems where multiple transactions may occur simultaneously. Proper handling of the transaction state is crucial for critical applications, such as financial systems and booking platforms, where data accuracy is essential.
