Business Process Construction In Service Generating Platform

SOA (service-oriented architecture) is a component model, its main idea is to integrate the existing software source which is cross-platform and cross-language, so that could be complete complex distributed computing. SOA defines several specifications to construct SOA Enterprise Business Applications such as UDDI,WSDL,SOAP, which are based on XML. So these specifications are independent of hardware platforms, operating systems and programming languages. This makes web services be able to interact and collaborate in a uniform and universal way.After defining and encapsulating reusable software components—web services, it’s important for business people to reconstruct business applications through interacting and assembling the web services quickly. Business people are allowed to write BPEL codes to assemble web services by hands, or choosing visual development tools to generate BPEL codes to assemble web services. Although these visual development tools accelerate to some extent the efficiency of the construction business processes, these tools all make the abstract models based on BPEL elements and corresponding attributes.Hence, when business people use these tools to construct business processes, they are not only familiar with knowledge and needs of the business in specific areas, but also need to know the details of the BPEL syntax. Thus it’s limiting the further improvement of development efficiency.Compared to the general visual BPEL-based development platform, the abstract model of service generating platform described in this thesis faces the web services specified areas directly. And through friendly visual interface to display services component in database to business people. Business people only need to drag and drop graphical components of web services to construct business process, the service generating platform could automatically generate BPEL codes and corresponding attribute values. Thus not only further hiding some details of BPEL syntax, but also avoiding business people to set a large number of values of BPEL elements attributes. So business people can construct business applications through facing business and needs of domain-specify directly. Thus it’s further improving development efficiency and reducing the development cycle.The main works of this thesis are service query and recommendation methods of web services based on the context of business processes and service-oriented construction techniques and methods of business process.
