What other DBMS should support my open source Java support library

Question

I am releasing a new version of jOOQ , a Java save library built on top of JDBC. I currently support these seven RDBMSs:

• Oracle
• MySQL
• Postgres
• H2
• HSQLDB
• DB2
• SQLite (experimental)

With jOOQ, I want to provide both broad and reliable RDBMS support. This means that I must be selective enough to ensure the reliability of my integration tests. At the same time, I must meet the needs of end users in supporting important databases. I expect my end users to rely heavily on their databases. jOOQ is not an OR-mapper. Au contraire, jOOQ covers vendor-specific functions, such as stored procedures , so the underlying database really matters to me.

In the next release, I want to add additional RDBMS support. For instance:

• MS SQL
• Derby

What would you suggest and why? Please explain based on objective grounds and state your recommendations.

UPDATE

The following DBMSs are now supported. Thanks again for the tip.

• Cubid
• Derby
• Ingres
• SQL Server
• Sybase (both SQL Anywhere and ASE)

Answer 1

With the Ringbearer sybase offer and your list of MS SQL and Derby, only the big ones are left, these are Ingres and Firebird.

IBM also has a second Informix database, but I know nothing about it except the name :)

Answer 2

Sybase - why? many systems still run sybase; especially in the field of health. Sybase is an industry class and multi-functional product. +1 for the project. I went through the site and I am impressed.
