Package org.dasein.persist Description

The Dasein Persistence Libraries provide data access tools that support the development of database applications. For simple database applications, automated persistence tools like Hibernate are definitely the way to go. Where the database is your performance constraint or where you are faced with legacy or complex data models, however, automated persistence often falls apart.

This package supports a variety of functionality, including:

• Database-independent sequence generation.
• Transaction management.
• Implementation of the classic memento pattern.
