Haiqing Bu · 2011
Service Oriented Architecture (SOA) is becoming an increasingly popular architectural style for many organizations due to the promised agility, flexibility benefits. One of the prominent principles of designing services is the matter of how abstract services should be i.e. granularity. Since service-oriented analysis and design methods lack on providing a quantitative metric for service granularity level evaluation, identification of optimally granular services is the key challenge in service-oriented solution development. This paper is divided into three types of services, and listed on the properties of service granularity. Various properties of the three service types the weight is not the same, in order to get the appropriate service granularity, Using the analytic hierarchy process analysis of the attributes in each service type.
