Subject Re: RunRules for JDO TCK
Date Fri, 06 Jan 2006 02:46:45 GMT

I'm inclined to agree with Andy that the schema and orm files for  
each of the databases we know of should be standard and specified as  
part of the TCK.

There is nothing in the TCK tests that should be different in the orm  
files from one database to another. There are differences in the  
schema based on column data types, and these differences can be  
captured in database-specific .sql files.

The only thing we lack is broader testing on different databases. But  
for now, I'll be happy to require that the orm files be identical  
among different databases, and even happier if we can get some folks  
to create the xxx.sql files for databases other than derby.
