How does DB2 ensure data integrity within databases?

  • ACID properties, BASE properties, CAP theorem, No data integrity mechanisms
  • Data redundancy, Data inconsistency, Data fragmentation
  • Referential integrity, Constraints, Data validation rules
  • Transactions, No support for transactions, Data replication
DB2 ensures data integrity through various mechanisms such as referential integrity, constraints, and data validation rules. Referential integrity constraints enforce relationships between tables to maintain data consistency, while constraints and validation rules define permissible data values and ensure data accuracy. By adhering to these principles, DB2 maintains the integrity and reliability of the stored data.
