>It's excellent! It is a FULL functional and ANSI 92 compliant DBMS. It includes inheritance (Table B can inherit columns from Table A), user defined functions, Transaction Tracking, commit and rollback, stored procedures, etc.... On small record sets it is not as fast as MySQL but after you get over 50,000 rows it evens out. When you get to really large datasets it shines. You have to tune it correctly and use vaccum.

Thanks for the info. This is my action plan for now: I'm asking MSFT very carefully about the licensing issues of MSDE in a wwwc environment. If there is any problem with licensing issues, I'll do a prototype in postgreSql.
