The Research On Approach Supporting Action Semantics Model Transformation

MOG (Model Driven Architecture, MDA) proposed model-driven system structure andvigorously advocate this approach to software development. It is a UML-based framework;the core idea is as a basis of model for all software development processes are based on it,which is through model to drive software development. In traditional software developmentprocess, we are generally set code as the focus of development, model just as asupplementary tool in early stage. With the rapid development of the computer industry, moreand heavier development work makes the programmer struggling to cope with, and a lot ofdevelopment work is repetitive and a waste of development resources, in this case, themodel-based MDA development method has become an inevitable trend, it is bound tobecome the mainstream of software development thinking.In Web development, there are many MVC model based on the framework to supportthe work flow model, and the model conversion method of action semantic support isinsufficient, it is difficult to complete workflow dynamic semantic conversion, so in manymodel transformation approach which oriented framework not support workflow conversion.This paper analyzes the current domestic and international research on MDA status,combined with related theory and MDA existing model transformation technology, aiming atthe model transformation of action semantic support is insufficient, put forward a kind ofsupport action semantic model transformation method. Its core is the source model and targetmodel of abstract element model, defines the corresponding model transformation rules tocomplete the PIM to PSM conversion. This article combined Seam development frameworkto set a case study of a model turn, describes how in a specific application using this modeltransformation method.The proposed method of this paper to solve the problem of present model transformationwhich lack of endorsement for action semantics in a certain extent, and combines the latestdevelopment framework MVC, to prove the usefulness of the method. The innovation of thispaper is to:(1) Showed a conversion method that support action semantic transformation ofPIM models to PSM model;(2) Proposed a conversion method that support theWORKFLOW and MVC of PIM to PSM.
