ACID Properties in Database Management System (DBMS)

ACID stands for Atomicity, Consistency, Isolation, and Durability. These properties are crucial in ensuring data integrity and reliability in a database management system:

  • Atomicity: All transactions are treated as a single unit of work, and either all actions within the transaction are completed successfully or none of them are. This helps maintain data integrity.
  • Consistency: The database remains in a consistent state before and after the transaction. This means that data must meet all validation rules, constraints, and relationships.
  • Isolation: Transactions are executed independently and are not affected by other transactions running concurrently. This helps prevent data corruption and maintains data integrity.
  • Durability: Once a transaction is committed, the changes made by the transaction are permanent and will not be lost, even in the event of a system failure. This ensures that data is never lost or corrupted.

Understanding and implementing ACID properties are essential for designing and managing efficient and reliable database systems.
