[Building Sakai] about insert data in the database

[Steve Swinsburg]

Hi,

You can use Hibernate to do this for you or you can do it yourself via  
JDBC. For Hibernate, in its simplest form you setup a Hibernate  
mapping file (hbm.xml) and a Java class for each table that you want  
in the database. The DAO simply abstracts the hibernate methods into a  
simple get/insert/delete fashion. I recommend this book to start with  
Hibernate:
http://books.google.com/books?id=0d12xElRjysC

As you read, keep in mind that Sakai already has the SessionFactory  
setup so you don't need to setup the configuration yourself, you can  
just inject it.

If you want some sample code, either use the app builder or see this  
quickstart:

cheers,
Steve
