Hibernate is used to persist the objects in the database, but we have to use the jdbc to connect to database. JDBC is used to store the primitivies in the database.
Hibernate is basically a ORM tool which allows you to perform database activies without bothering about the Database change.
You dont need to change the SQL scripts if you change database.
Apart from that you dont need to write most of the SQL scripts for persisting ,deleting object and parsing the resultsets.With respect to perfomance, hibernate provide the capability to reduce the number of database trips by creating the betch processing and session cache and second level cache.
It also supports the transactions.
More then this all, it is very easy to make a cleaner seperation of Data Access Layer from usiness logic layer.
With all the capabilities mention above it is fast and easy to learn hibernate, develop application and maintain easily.
