A New Approach to Increase Information Systems Modularity using Event-Driven Software Architecture

Software production line is one of the most active trends in software engineering. Most available methods are based on tripod architecture. In this paper, it is provided new frame with100% extensibility for data access layer. It is such a frame which can be used for all information system in all sizes. The difference of this method with the others is that the others are used to produce data access layer codes based on data model in the software production line. While it is suggested a main module as well as a tool based on designed patterns and innovations in this method which can be added to the available project and managed all the data access layer process and operation needless to produce any access layer to data for each project. By using this frame of data access layer, the projects are always ready and available and can be used in different projects without change.
