    so why are you asking all these questions?

    how to store data in relational database: with the INSERT statement

    how to query the data: with the SELECT statement

    Is there a open source relational data base? yes, MySQL, Firebird, PostgreSQL, ...

    the data structure that is used by SQL Server is called a B-tree. other DBMS use other data structures.

    when you find someone with deep knowledge, please let me know. everyone I know is a hack.
    “If one brings so much courage to this world the world has to kill them or break them, so of course it kills them. The world breaks every one and afterward many are strong at the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry.” Earnest Hemingway, A Farewell To Arms.
