Handling stale data on End User

[Vinaya Tirikkovalluru <vi...@converge.com>]

Hi,

I have a situation below..

User A and User B queried the data for a part and are in edit mode.
User A updates the part successfully. As user B is still in the screen,
he does not know about the update. Now user B updates. Is there a way to
show the user that the data is already stale to User B in Ibatis/Spring
which makes it easier? 

Thanks
Vinaya

There's nothing automatic in iBATIS to deal with this.

I suggest you do some research on "optimistic locking" - this is the
most common pattern for dealing with concurrency issues in the web
world.  iBATIS supports an optimistic locking strategy, but you have
to implement the SQL yourself - and design your tables properly.

Or - you can just let user B overwrite user A's changes.  In reality,
this is probably the most common pattern :)
