Java distributed database data sharing

I want applications to share certain database data. I want one application t开发者_Python百科o retrieve and display certain table views of data produced by another application. Do you know of any open source technologies that I can use for such a distributed solution?

It sounds like you just need an open source RDBMS (of which there are a number; e.g. MySQL, Postgres, Derby, Firebird, etc) and matching JDBC drivers.
