A dao layer over JPA. With this library, you work with objects and lists of objects. No sql. Select queries can be made with a Search or Search2 object.
You can download and open this project in NetBeans 10.x. It's a Java 8 maven project. So, dependencies are loaded automaticly from maven central. There are some test classes where you can learn how to use this library.
In MacOS terminal or Windows console, you can start the "test" suite with a Maven command :
mvn test
