Creation, DESTRUCTION and access will typically be more time consuming and expensive for persistent objects STORED in the database, than for transient objects in the TRANSACTION’s local memory. This is because of the over-heads in preserving transaction semantics, security and integrity. Since a transient object is purely local to the transaction which created it and does not enter the database, all these over-heads are avoided. Thus, in order to provide EFFICIENT access to purely local and temporary data, transient objects are provided by persistent programming languages.
