Using J2EE is not a solution to replace RDBMS.
J2EE is just a normed platform you can use to build you N-tier application.
The first Tier is the client (browser, wap, java)
The second tier is the middleware (WebServer, application server)
The third tiers is the Enterprise Information System. It is your RDBMS if you use one.
EJB spec just specifis how you will "design" your access to the RDBMS, using entityBeans and persistence mechanism for example.
But the data are still saved in a database.
Just let me know if I missed something.

Does CMP of EJB 2.0 support table relationship? I know CMP of EJB 1.1 does not.
If the relationship is supported how is it mapped, automatically, or a lots manual work ?
