Meanwhile, the main focus is the design and implementation of the visual rules editor (based on eclipse plug-in) and the rule execution engine which is followed by the JSR-94specification. Finally, the analysis on the effect of the system is performed, and the maintainability and flexibility of the system are analyzed and summarized.
