The Design And Implementation Of Application Systems Based On SOA

The application of service-oriented architecture (SOA) can enhance the flexibility, reusability and scalability of software systems. SOA has become the mainstream of enterprise application development methodology.Firstly, this paper summaries the concept of SOA and related technologies and analyzes the development methodology of SOA. SOA-based software development cycle is divided into seven stages of project planning, service-oriented analysis and design, service development, service testing, service deployment and operation and maintenance services.This paper focuses on the service-oriented analysis, design, and development thoroughly. And this paper expounds a kind of software architecture based on SOA, which is composed of application logic layer, service component layer and service implementation layer. Then, a set of analysis and design methods oriented on service are presented. And this paper introduces a Workflow-driven service flow model. This model is mapped with the standardized workflow model and uses workflow engine to drive service components, to realize the service dynamic Integration and reuse, and use mashup technology to achieve data integration of the same web services.At last, this paper introduces the design and realization system of Online Bookstore based on SOA. And this paper expounds the implementation of main stages in the procedure of service-oriented system analysis in detail. Then it introduces the design process of service-oriented system architecture, workflow-driven service flow model. And an implementation scheme of online bookstore system is given.There search of this work can provide a reference for system development practices based on service-oriented architecture (SOA), in the Internet.
