基于SOA的流程与数据集成

在企业IT系统设计与开发过程中,流程建模、数据建模和构件开发之间缺乏有效关联,严重降低了软件系统开发的效率,增加了软件开发的复杂性.本文基于面向服务的体系结构(SOA),深入研究流程组合、构件开发和数据建模之间的关联关系,提出集成业务流程与数据模型的方法.该方法通过分析流程模型与数据模型所包含的数据之间的映射关系,并捕获流程中的数据访问流,构建出平台无关的流程数据关联模型,然后根据流程数据关联模型,自动生成合适粒度的数据访问构件,并利用数据访问流所包含的全局信息优化数据访问性能.

Process and Data Orchestration Based on SOA

Under the service oriented architecture(SOA),process design,software component design and data design are usually performed relatively independently by different roles with different methodologies.This results in a gap among business process modeling,software component design and data modeling.A process and data orchestration solution design(PDOSD)method was proposed to bridges the gap between process design and data design through gluing the artifacts in the two sides together with machine generated data access components and optimizing the design at both sides for performance improvement in this paper PDOSD at first builds a platform independent process and data associated model(PDAM),then generates data access components with appropriated granularity through analyzing the data mapping relationships and data access flows.Furthermore the data access process can be optimized through utilizing some extracted rules.
