Should it be done via a mapping to SQL? Then it is not our job but rather an issue for the prevayler project. Of course, the SQL must refer to a virtual O/R-mapping then. Or should it support the PB query API directly? What about those features in the API that refer to the Database schema directly (such as SQLQuery)? > Any ideas for this are welcome.

For prototyping and testing, HSQL is sufficiently convenient, and in real life, customers want RDBMS. That is my what I guess at least. regards, Olli --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
