1) data restriction
数据约束
1.
This paper presents a method isolated workflows, which separates data from tasks, by using data restriction and task restriction to ensure workflow execution correctness and alleviate the complexity of workflow, and uses the expression power of consistency constraints in a database query language (SQL) to achieve workflow concurrency control.
给出一种基于将工作流中数据和任务分离的工作流并发控制机制,在保证工作流正确性的前提下,引入“数据约束”和“任务约束”的概念来提高工作流的工作性能和降低工作流设计的复杂性,并用数据库中SQL语言强有力的约束控制加以实现。
