Basically yes, there are two reasons why we didn't use that
schema/database:
1. the development of our project started a little bit earlier than I
got familiar with Jetspeed and it's calendar efforts
2. the development of the "back-end" is not directly my responsibility.
And as I have had enough of new stuff to learn, I've tried to keep it
that way.
3. Our current database of choice is MS SQL and communication with MS
software from Java is a hack... Finally we ended up writing the DB
access classes in MS Java and then calling these classes over RMI from
Jetspeed/Turbine.
Why MS SQL in the first place? As we are under time pressure to come up
with the beta of our project, and we knew MS SQL before, we couldn't
afford to learn yet another new product. And we need something fully
featured: DB server with transactions, triggers, stored procedures,
on-line backup, etc. (The DB is not only for calendar, it is the
backbone of all our current and future services, including also
e-commerce, etc.)
Our goal for the future is to move to totally open-source software
whereever possible/feasible: the most likely candidates for our DB
server are PostgreSQL or Interbase. But the current state of both of
them doesn't meet our requirements yet.
After we have made the launch of our service and start to port our stuff
over to some open database, we will most probably do it in cooperation
with Jetspeed.
