Hibernate - Basics

[Bhairava Surya]

Hi All,

I started learning Hibernate, but I didn't understand why hibernate?
I have gone through so many tutorials over net, but I am not satified with anyone of the answers.

1) Just please help in understanding why hibernate with some basic examples which we cant do using JDBC
2) Before hiberante how are we achieving ORM.
3) whats the problem with normal JDBC/SQL.
4) What are the other tools/applications which are similar to hibernate

Thanks & Regards,
Ravi.

1) Hibernate generates JDBC-statements, so there isn't anything Hibernate can do, you couldn't do with JDBC by yourself.
3) JDBC doesn't feel that much object-oriented. Code is (or might be) ugly to maintain.
4) Toplink

Have a search for something called the "object relational impedance mismatch". This is the main reasons why ORM's exist.
