Application And Research Of MDA In Sales Management System

With information technology developing rapidly, the demand about the development of software is higher and higher now. The traditional methods of developing software can't solution well the problem that disconnect between documentation and implementation and different platforms need to repeat modeling, which has obsessed software developers. In this case, Model Driven Architecture makes above problems solved well.In this paper, MDA was applied to sales management system and the transition rules of the system were defined. The realization of the system mainly divided into the following steps:firstly, we analyzed the function demand of sales management system and modeled a CIM Independent Calculation Model. Secondly, we set a Platform Independent Model of system, according to the definition about the traditional rules of CIM to PIM:according to the definition of boundary, control class, entity class, and the functional requirements of the system analysis, we transform CIM model into the border, control class, entity class for PIM. Then, we transform PIM into PSM, whose transformation rules goes as follows:according to analyzing the border of PIM, we got the PSM about said layer of Web. Secondly, business control layer in PSM:seeing the business process of every step, we set the dependent method of the public operation part. Thirdly, data layer in PSM:①We specified the main key in each class as an attribute.②In transition, class name directly converted into the date table, the name of the kind of attribute converted into the date table, type of class corresponding column attribute type allowed in the database.③Relationship among classes was transformed into corresponding relationship among data tables.Finally, we set database base on the PSM data layer. Based on the front model, we made the system of sales management used through programming. The application and research on MDA in sales management system were finished.
