DAS Reference

This is a quick reference of the Data Access Strategies available with the rsh-dal project:

JDBCStrategy

This DAS provides data access using straight, plain, old-fashioned, you-get-the-idea JDBC calls. The only "innovation" is that it makes use of handler classes to delegate loading and unloading data from the model to the SQL query. It also makes use of a QueryManager for managing SQL.

When you combine it altogether, it is almost an ORM setup, but without all the object management and state tracking you get with full-blown ORM packages (like Hibernate3 or TopLink).

Hibernate3Strategy

This DAS provides data access using Hibernate3. You gain all the advantages of using Hibernate3 along with a few extra goodies (like being able to use it in or outside a container without having to change configuration).
