There is nothing that hibernate can do but JDBC cannot. Basically, JDBC is the bottom layer of hibernate library. It just gives you some advance functions to perform a database operations. But at the ground level its JDBC which is directly interacting with database.

JDBC is one the technoloogy of JSE module in JAVA,but
HIBERNATE is one of the ORM tool to connect to database,its
internally uses JDBC technology providing some extra
functionalities.
1.------using JDBC to connect any database having
drawbacks,if we want to connect to database
Connection,Statement,ResultSet objects must otherwise we
cant connect here manually programmer created reference objects
-------using hibernate no need to create
Connection,Statement,ResultSet objects hibernate will
create, as aprogrammer just using that objects to connect
database,just configuration file need
2.---------using JDBC we unable to store objets directly in
databases, we need serialization for convertiong text to
object viceversa
------------using Hibernate no need directly we cand store
objects in database
3.-------as a programmer need to close con,st,rs objects in JDBC
---------no need, here Hibernate will take care for closing
con,st,rs objects
4.Comare to Hibernate JDBC is fast because its simple java
program not like big program(cfg,hbm files)
