A SaaSI: an approved architecture for SaaS service composition

With the development of internet and web2.0 technology, Software as a Service (SaaS) has been accepted as the main way of software service delivery. However, the SaaS applications are isolated and cannot fulfill the rapidly change of business requirements. In this paper, an approach to integrate SaaS services is proposed using the integration architecture discussed, and several critical problems in the presentation, function and data layers are solved. So developers can easily combine the SaaS offerings to meet new business scenarios. We implemented the supporting platform and put it into real practice in a large-scale car manufacturing factory in China.
