Hi all,
We are developing an integrated accounting-inventory environment under J2EE.
Say Entity A is responsible for general ledger(GL) accounts and Entity B
handles inventory. According to the current requirements, each inventory
item contains 3 account IDs from GL.
My question is about the best place to put ID validation. One approach is to
ask Entity B to do this. Based on this approach Entity B does validation by
getting a reference to Entity A and asking it to validate ID. Another way is
to have a session facade to fulfill this. It means that session facade will
has a reference to Entity A and validates IDs before delivering them to
Entity B.
Thanks in advance,
Mohammad
