Research And Implementation Of Service Discovery Method For BOSS System Based On SOA

The BOSS system is facing the rapid change of business development needs nowadays,and many companies have used the Service Oriented Architecture(SOA)to build their software systems.While using SOA,the system has an ability of constructing business processes.Therefore,how to refine the business into a precise service has become the top priority of the process.Current SOA methods only provide a brief description of the content and have no introduction of the results of usage.This paper determines the steps and key factors of service discovery by describing how to implement SOA of the BOSS system,and with a practical project as a background,analyzes and researches the services which are structured by business in depth.The main work of this paper is as follows:First of all,this paper chooses service oriented modeling and Architecture(SOMA),a service modeling methodology,and predicts its performance.The method theory is mainly responsible for providing the service identification method in SOA implementation,and guiding developers to implement and make specifications of services.This paper takes an example of a real business process,and applies the SOMA to the process to predict its performance in the usage of the whole system.Secondly,using SOMA methodology to discover the services of a BOSS system.This paper takes a business scenario in the BOSS as an example,and respectively using SOMA methodology of three kinds of service discovery method for BOSS system for service discovery.At the same time,according to the results of the service discovery of the BOSS system's business process,this paper gives the performance of the three methods in SOMA methodology,and determines the characteristics of each method.Finally,in this paper,the simulation of business process which is based on the application results of SOMA methodology is given.According to the result of service set discovered by SOMA methodology,WS02 software is used for the multi-role process simulation.The simulation integrates service reuse and service assembly and etc.which required by SOA services processes.In this way,this paper verifies the method that proposed in this paper according to the SOMA method on the correctness and feasibility which used in service discovery.
