RE: Java and CPU

["Joe Pluta" <joepluta@xxxxxxxxxxxxxxxxx>]

Again, I concur, Larry, with your sage remarks <smile>.  For most of my
development, I use both a thick client and a thin client interface; by using
the thick client I can debug everything quite easily on my PC.  I'm slightly
ashamed that I've yet to learn how to debug servlets directly in Visual Age;
in fact, I'm not even up to 35 of VAJ yet, but I will be as soon as the new
AS/400 comes in next week.

As to the encapsulation of database I/O, I highhly recommend a level of
object abstraction so that you can easily plug in native DB2 access (I use
message-based calls to a server) as opposed to SQL.  As I've pointed out,
native DB2 is much faster than SQL for many things, and it's generally a
good idea to allow either.  Heck, it's generally a good idea to separate
your business object and data source design anyway - this is the first step
towards the componentization  required for EJB, anyway.
