Service Oriented Architecture (SOA) is an approach for building distributed systems that deliver application functionality as a set of self-contained business-aligned services with well-defined and discoverable interfaces. It can use coarse-grained services as well as fine-grained services. Both of them have their advantages. In the backdrop of railway information sharing platform, we propose a division method to decide the appropriate level of service granularity. The proposed method divides the services into three parts: basic service, combination service, integrated process service. Each service has its scope and combination. An application example is used to illustrate the method.
