基于MDA的SaaS服务模型的设计与实现

Design and Implementation SaaS Service Model based on MDA

SaaS模式以其低成本、短时间构建的优势已渐趋成为传统软件的备选方案。随着软硬件技术的快速发展,IT行业面临最大的挑战就是技术的过时,提出一种软件开发方法来缓解技术变革所带来的不良影响是十分必要的。本文在深入分析SaaS模式技术特征的基础上,尝试使用MDA方法开发云软件应用程序,通过MDA方法与云计算的有机结合,为用户提供更为健壮的、灵活的和敏捷的软件解决方案,以降低不断发展的技术所带来的不良影响。

SaaS has increasingly become alternatives of users for its lower start-up cost and building time. With rapid transitions in hardware and software technologies, the biggest challenge posed to the IT industry is technology obsolescence. There arises a need for a software development approach could mitigate the undesirable effects of technology change. In this paper, on the basis of embedded analyzing technical characteristics of SaaS, we try using MDA approach to develop cloud application. We try to ensure software solutions are more robust, flexible and agile, in the wake of constantly evolving technologies through the combination of MDA approach and cloud computing.
