Details on the database schema and directly accessing the database is neither supported nor recommended. This is due to the data abstraction layer provided by the Jazz Foundation and not having explicit schema control.
Schemas can change, and what works now may break in any future major release.

Yes I agree that Schemas keep changing with releases but it would be nice to have basic idea how tables are related so that it would be easy for customization or extending the applications from user perspective.

Understand your need, but extending an application by directly working against the database will get you into trouble soon, hence not supported and recommended.
Like mentioned above, abstraction and persistence layers from Jazz Foundation, and for example the Jena library to store linked RDF data, make it a it an almost impossible route to embark on.

Speaking for DNG, the three API's that are public for you to extend DNG for your users:

RRC Reportable API - for reporting purposes, only reading artifacts

OSLC RM V2 API - the open standard way to programmaticaly integrate with DOORS NG, there is an elaborate workshop to get you started here OSLC Workshop article

and additionally, there is the so called client extension capability

It's all about the answers!
