【摘要】 针对目前各个系统中对过程模型采用不同表示方法的现状,提出了一种面向异构过程库的通用过程查询策略。该策略以工作流元模型为基础,采用通用过程查询语言表达查询请求,并通过参数化模板生成针对各个过程库的具体查询,实现了异构过程库的联合查询。更多还原

【Abstract】 Current process query methods adopt different representation method for process model in various systems.To solve the problem,an approach of general process query strategy oriented to heterogeneous process repositories was introduced.This strategy was based on workflow meta-model,and a General Process Query Language(GPQL) was adopted to express query demand.Parameterized templates were generated as concrete query to different process repositories so as to realize united query for multiple heterogeneous process model repositories.更多还原
