HIBERNATEHibernate 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 hibernateHibernate can save your guts, and it can let

you achieve some performance gains that you could hardly ever acheive by hand-coding.

Hibernate generates very efficient queries very consistently. However, that is only the begining of the performance story. Hibernate employs very agressive, and very intelligent first and second level caching strategy. This is a major factor in acheiving the high scalability.

Why use hibernateHibernate 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 hibernateHibernate 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.
