摘　　要：传统的分布式工作流系统常常将服务粒度划分过小,虽然这种服务设计简单、可重用度高,但处理复杂业务逻辑时通常要多次请求服务才能完成,频繁请求服务导致系统性能降低,由此本着粒度适中、易用的原则,给出一种构建粗粒度服务的方法,且能保证服务的高度可重用性。Workflow has been widely applied to enterprise business application. The separated granularity of web services in the traditional distributed workflow system is often very small, which definitely reduces the complexity in the architectural design of the system. But this brings in extra more requests for service when handling complicated business requirement, which leads to depreciation in performance and response speed. Consequently, a strategy on constructing coarse-grained web services is presented to improve the reusability of service and performance of overall the system.
