Information Appliances Based On The Ejb Tier Model Architecture Software Product Line

Computer use in the wide variety of industries, requires a lot of software as a support, a growing number of software companies found that the traditional way of developing a software one time can not satisfies demand, they need to improve the efficiency of software development, and production methods based on software development can solve this problem. For these reasons, in the field of information appliances, the people combine the software product line and air conditioning industry, combine the software product line of the key methods and techniques and software product line practice to eventually form a new, complete field engineering method and auxiliary software engineering environment.This thesis analyzes related technical and standards of software product lines in current industries, and proposed software product line model of information appliances based on SOA architecture. Furthermore, in this thesis, the existing four-EJB architecture is analyzed to illustrate the traditional architecture can not meet the needs of today's software development. On this basis, the thesis deeply researched options of each layer of the architecture model, proposed a kind of layer model architecture based on EJB component, which is the improvement of traditional architecture.This thesis applied this framework to platform of software product line of information appliance to prove the feasibility and practicability of the framework. The platform provided users with the corresponding core asset generation tools, product assembly tools and management tools. Through the visualization process configuration, this thesis implement a software product line customized production process. The software product line brought great convenience to the developers in the field of the information appliance, and realized the industrial assembly line of software in the field of information appliances.
