Implementation of a tracking mechanism of executive instance information in SaaS application

SaaS and multi-tenancy has become a trend which gets more and more popularity. On this basis, how to monitor the information of SaaS service process and the instance information of every service of the interaction is an important problem. Based on the model of interaction-oriented SaaS application support for multi-tenancy, this paper proposes a mechanism for tracking the business instance of SaaS service. This mechanism uses BS-BPEL as the inter-model. It can achieve the model conversion from the state-based model to the structural-based model and realize the information mapping from interaction service instance to the activity in BPEL. Thereby, the visual display of business instance information can be realized.
