BPEL Based Service Process Configuration in SaaS Application

SaaS system uses a single instance to meet the multi-tenant demand. In traditional information systems, in order to meet customer’s ever-changing business requirements, generally took the second development to improve existing software systems, but it would cause a certain lag. During the second development, customers can only use the original software system. It not only affects their work efficiency, but also requires programmers to improve the system within a short time. It is a large degree of challenge, and the quality may be a trouble. To solve this problem, SaaS applications take use of customization and configuration to deal with. SaaS can quickly adapt to requirements changed, maintain easily, and cost properly. Among these, one factor which promotes the development of the SaaS is that system can be configured by tenants. Specifically, through combining the tenants’ business processes configuration with function configuration to further meet the diverse needs of tenants.
