| 摘要: |
| QVT(Query/View/Transformation) Relations 无法描述包含嵌套模式,因此在描述流程模型的转换规则时存在一些困难.针对此问题,对QVT Relations 进行了扩展,引入了模式因子、嵌套关系表达式和关联端约束这3 个概念,并讨论了扩充之后匹配模型和创建模型的语义变化.并用一个例子展示,扩展之后的QVT Relations 可以解决流程模型转换的问题. |

| Abstract: |
| QVT (Query/View/Transformation) Relations cannot describe the pattern that includes other patterns, so it has some difficulties in defining the rules of a process model transformation. To solve this problem, the paper extends QVT Relations with three new concepts: Pattern Factor, Nested Relation Expression, and Relationship End Constraint. The paper also discusses the pattern matching and the model creating semantics after the extension. At Last, a case study is presented to show how the extension could deal with process model transformations. |
