Hi , everyone:

Is hibernate server running in the background ,

when we run a java program which uses hibernate as the perisistent layer?

how does hibernate intergrate with MySQl?

thanks.

Best regards.

Hi,

Hibernate not a server. It is actually not more than a set of libraries you can use to get your data in an out from your database. You can either deploy it on a web or application server (i.e. Tomcat/JBoss) or it can run alongside your standalone program.

A good starting point is to check out http://www.hibernate.org/hib_docs/v3/reference/en/html/

Or if you want to start using Hibernate Hibernate: A Developer's Notebook (Jim Elliott/O'Reilly) is an easy and good book to start with.

To answer your question about how it interacts with MySQL - it uses JDBC under the covers, the same as it does to work with any other supported database.

At a high level, Hibernate is an Object Relational Mapping tool that allows your OO Java application to work with data as objects that represent relational data in your database. Under the covers it is sitting ontop of JDBC. Rather than you writing JDBC code to map your objects to relational tables and vice versa, it executes the necessary JDBC code for you. It does this based on the mappings that you must define to tell it how your objects map to the tables.

Get a copy of Hibernate in Action - its still the best book out there so far.

Hope that helps.
