What role does transaction management play in ensuring data integrity in DB2?

  • Transaction management automatically resolves conflicts between concurrent transactions.
  • Transaction management enforces primary key constraints on database tables.
  • Transaction management enhances query optimization for improved performance.
  • Transaction management ensures that database operations are performed atomically, consistently, isolated, and durably (ACID properties).
Transaction management in DB2 is crucial for maintaining data integrity by ensuring that all database operations adhere to the ACID properties. It guarantees that transactions are executed atomically, meaning they either complete successfully or are rolled back entirely. Additionally, it ensures consistency by enforcing integrity constraints and isolation to prevent interference between concurrent transactions. Finally, transaction management ensures durability by persisting committed changes even in the event of system failures.
