From One of a Book, there are 3 ways to handle Concurrent updates.
For Ex., If P1 and P2 is updating A by changing a values in attri1,attri2 and attri2,attri3 respectively.
1. Always overwrite with lastest update on this object - Result : attrib2 and attr3 will have latest data. attri1 is older than P1.
2. Throw exception for the second transtaction Result : Only attrib1 and attr2 will have latest data. attri3 is older than P2. P2 should redo the task.
3. Merge the changes from both the transactions - Result : attrib1 and attr3 will have latest data. attri2 will have the update of P2.
Anyone tell me how to implement the third approach in hibernate.
Thanks in advance
