Hades¶

Overview¶

Hades is a utility library to work with Data Access Objects implemented with Spring and JPA. The main goal is to ease the development and operation of a data access layer in applications.

To get a first impression of what the library can do for you, you should read the Rationale. A good next step might be reading through the reference documentation.
