Robert Krueger asked why Caching is a value-add of CMP and why BMP prevents
you from caching.

The answer is that BMP doesn't prevent you from caching if you have a
single application doing all database updates via a single cache.

However if the database is accessed both via the cache and via other
mechanisms (eg there could be a Client-server SQL application also
accessing the database, or there could be two systems sharing the database,
each having its own cache) then CMP is necessary because the container
needs to know if the data in the cache is current and this requires the
container to know the relationship between cached objects and database
records.

With BMP this knowledge is buried in the application.
