What does the acronym ACID stand for in the context of database management?

The acronym ACID in the context of database management stands for Atomicity, Consistency, Isolation, and Durability. Each of these principles is crucial for ensuring reliable transactions within a database system.

Atomicity guarantees that a transaction is treated as a single, indivisible unit. This means that all parts of a transaction must be completed successfully for the changes to be committed; if any part fails, the entire transaction is rolled back. This ensures that the database is never left in a partially completed state.

Consistency ensures that a transaction brings the database from one valid state to another valid state, maintaining all defined rules and constraints. This means that any data written to the database must follow the schema, and integrity constraints, protecting against corruption.

Isolation ensures that transactions are executed in isolation from one another. Even when transactions are happening concurrently, isolation ensures that they do not interfere with each other, preserving accuracy and reliability in the final state of the database.

Durability guarantees that once a transaction has been committed, it remains so, even in the event of a system failure. This property ensures that the results of a transaction are permanently saved and can be relied upon.

Understanding ACID properties is essential for maintaining data integrity and reliability in database management systems. These principles form
