What is concurrency in db2?



What is concurrency in db2?..

Answer / vasuki🐍

Concurrency is the ability of more than one application process to access the same data at essentially the same time.
However, DB2 use locks to control concurrency to prevent lost updates and such possibly undesirable effects as unrepeatable reads and access to uncommitted data.
locks ensure that no process accesses data that has been changed, but not yet committed,
