>Is there a open source relational data base?
MySQL.

Agree with narue, mysql is a very good open source database. What are you looking for about your select statement that is different than the rest?

1: Is writing queries ......
2: Knowing the actual details of implementation in terms of Data Structures..

Your comments are helpful. Do you know a real open source database that i can learn from to know more knowladge about B+,B2 tree and other data structure?

MySQL isn't real? A good way to irritate the people who try to help you is ignoring them completely.

Asking a question on a forum where you don't seem to read the reponses.

If you want to know how a database actually works on a low level just consult a comp/sci textbook. Fundementally hashes, indexes, trees, linked lists are the key concepts involved. How they are actually used varies on implementation.
