HIBERNATE introduction

• Hibernate is a free, open source Java package
  that makes it easy to work with relational
  databases. Hibernate makes it seem as if your
  database contains plain Java objects like you use
  every day, without having to worry about how to
  get them out of mysterious database tables. It
  liberates you to focus on the objects and
  features of your application, without having to
  worry about how to store them or find them later.

Why should use hibernate ?

• Hibernate can save your guts, and it can let you
  achieve some performance gains that you could
  hardly ever achieve by hand-coding.
• Hibernate generates very efficient queries very
  consistently. However, that is only the beginning
  of the performance story. Hibernate employs very
  aggressive, and very intelligent first and second
  level caching strategy. This is a major factor in
  achieving the high scalability.

Why use hibernate ?

• Hibernate spares you a unnecessary database
  calls. So all these lookup tables, and rarely
  changing data can get cached, and much more.
• It allows you to cache how much you want, and it
  can be very intelligent with write-backs.
  Furthermore, it integrates well with the major
  open source (OSCache, EHCache, JBossCache, ...)
  and commercial caching products such as Tangosol
  giving you an opportunity to use even more
  sophisticated features that come with these
  products.

Advantages of hibernate

• Hibernate code will work well for all databases,
  for ex Oracle,MySQL, etc. where as JDBC is
  database specific.
• No knowledge of SQL is needed because Hibernate
  is a set of objects and a table is treated as an
  object, where as to work with JDBC, one need to
  know SQL.

advantages

•  Query tuning is not required in Hibernate. The
  query tuning is automatic in hibernate by using
  criteria queries, and the result of performance
  is at its best. Where as in JDBC the query tuning
  is to be done by the database authors.
