The modeling tool of SaaS software

In the SaaS application, users can order corresponding software services from the service provider according to their application needs and adjust their services content in use based on the changes of the enterprise development, with strong elasticity and expansibility. However, despite of so advanced concept of SaaS, there are still some problems in the SaaS field constraining the wider use of SaaS. At present the composing model of SaaS, the development method and the problem solving are all taken into account in some of the theories and applications, but no one discusses the description of the SaaS model. As we all know, the model is also the key to the construction of SaaS software development platform. The traditional modeling method based on the workflow asks for understanding the operation processes of all aspects of business for modelling personnel and needs the support of professional knowledge on updating and maintenance of business processes. How to adopt a common way to describe it and make it User-friendly search is a serious problem to be solved. Therefore, we propose SaaS service model based on extended WSCL, and implement the modeling tool of SaaS service model. This paper aims to develop a modeling tool to allow the modelling personnel to complete the modeling process through understanding the business, and the system can automatically convert the state diagram corresponding to the process into WSCL documents. The SaaS service modeling tools can help developers easily model for the SaaS service, which makes the modelling process more formalized and visualized, and then make it easy to communicate with users.
