We can also plug in a clustered cache into Hibernate. At the time of providing cache we need to understand that when we are updating the persistence DB it willContinue reading “The Second Level Cache in Hibernate : Settings and Configurations.”

Executing SQL statements later, when needed. The session never issues an INSERT or UPDATE until it is actually needed. So if an exception occurs and you need to abort the transaction, someContinue reading “Advantages of Hibernate”
