A Hybrid Model Transformation Approach Based on J2EE Platform
Kun Ma, Bo Yang · 2010
Model transformation plays an important part in current MDD (Model Driven Development). For the development of J2EE applications, this paper presents a hybrid model transformation combined with direct model manipulation, transformation implemented using XSLT, relational algebra and template theory. This approach removes the heterogeneity of model transformation to some extent, and has the advantages of expansibility, cross-platform. Furthermore, this paper develops an extendible prototype system called extMDA based on MDA paradigm, taking models from UML tools and generating deployable J2EE applications by Hybrid Model Transformations. extMDA comes with a host of ready-made plugins of development toolkits like Axis2, Ibatis, Struts2, JSF, Spring and Hibernate. Finally the hybrid MDD process is discussed in detail by an example of Course Election System with good results, which is sub system of Postgraduate Education Management System.
