Re: mapping data

[Seth Gordon <address@hidden>]

If memory serves, one of the architects of JBoss said that the big 
bottleneck in a J2EE application is the time spent marshalling and 
unmarshalling data that's going to and from a relational database.  To 
avoid this problem, JBoss caches as much information as it can in Java 
objects, and minimizes the number of reads and writes to the database.

It seems to me that a good data-mapping system would solve the same 
problem in the opposite direction, so to speak.
