    jsimple.org

    jsimple.org

    Rapid Development Framework Based on the Java EE platform and Swing

    In a general way, we can define a jSimple as a piece of software that automatically connects persistent data (Entities) with the user interface (visual objects). We use the word "connect" because it implements all the logic that is needed to display persistent data and to make the user input persistent, creating or modifying data. The main benefit of using a jSimple is that it simplifies database applications development, because it takes care of all the technical aspects involved in moving data from the persistent to the presentation tier and vice versa, saving big amounts of code and lots of headaches.
