ACID Properties
The acronym ACID stands for Atomicity, Consistency, Isolation, and Durability. These properties are crucial for ensuring that data integrity is maintained within a database system.
Atomicity: An ACID property ensures that a transaction is either completed in its entirety or it is aborted completely. In other words, either all changes made by the transaction are applied to the database, or none of them are. This prevents inconsistencies and ensures that the database remains in a consistent state.
Consistency: An ACID property requires that the database must remain in a consistent state before, during, and after a transaction. This means that the database must always maintain the same values of data objects. For example, if two transactions attempt to update the same record, the database must decide which update to apply based on the ACID properties.
Isolation: An ACID property ensures that transactions are isolated from each other, meaning that changes made by one transaction are not visible to other transactions until the transaction is completed. This prevents data corruption and ensures that different transactions can operate independently.
Durability: An ACID property ensures that the changes made by a transaction are permanent and survive system failures. This means that even if the database crashes or is rebooted, the changes made by the transaction will be preserved.
These ACID properties are essential for maintaining data integrity in a database system. They ensure that data is consistently available, that it is not corrupted, and that changes are always applied in a reliable and predictable manner
