constraint n. 1.强迫,拘束。 2.约束,压抑,拘泥。 3.强制力。 4.紧张感[状态]。 by constraint 勉强,强迫。 feel constraint觉得局促不安,感受压迫。 show constraint显得局促。 under [in] constraint 被迫,不得不;被束缚着。
Object allows you to define foreign - key constraint rules 对象还允许定义外键约束规则。
Foreign - key constraint rule 外键约束规则
Columns that are defined with constraints follow constraint rules regardless of this setting 使用约束定义的列都将遵循约束规则,而与此设置无关。
Gets or sets a value indicating whether constraint rules are followed when attempting any update operation 获取或设置一个值,该值指示在尝试执行任何更新操作时是否遵循约束规则。
Under the background of packing design of bender , the packing algorithm of gradual advancement based on engineering - oriented constraint rule is presented 摘要以弯管机布局设计为背景提出了一种基于工程约束规则的层次推进布局算法。
Moreover , we accelerate solution of packing problem to make packing result accord with actual requirement by applying engineering - oriented constraint rule to packing 同时,在布局过程中引进了工程约束规则,加快了布局问题的求解,布局结果更符合实际要求。
The sufficiency function is built for genetic algorithm based on constraint rule , and the genetic / tabu algorithm is introduced to process aggregating . the feasibility and efficiency of the algorithm are verified by the result of example 将基因遗传/禁忌混合算法应用于加工工序的聚合问题,以工序聚合中的约束规则为基础,建立了摘要遗传算法的适应度函数,通过实例验证了混合算法的有效性。
A dynamic hierarchical description method for workflow is presented . the method provides a dynamic hierarchical way to define a workflow with non - determinate or dynamic factors . with this method , the main process defined at build - time can be reified and extended by the principle of the sub - organizations at either the build - time or the run - time . to ensure the consistency and integrity of the description , a series of constraint rules are also discussed to realize seamless integration between a decomposed process and its original one . this approach supports the description of unpredictable uncertainties , the dynamic hierarchy of business process , and the dynamic modification of enterprise organizations , and all of these improve the flexibility and extendability of workflow management systems dramatically 为支持流程中不确定性因素和动态因素的描述,提出了柔性工作流的动态层次描述方法,使得流程设计人员在流程定义阶段定义的主流程可以在任意时刻由子组织的负责人进行细化和扩充.为保证动态层次描述的正确性和完整性,讨论了动态层次描述的一系列约束规则,确保分解后的流程与原有流程实现无缝衔接.该描述方法支持对不可预知的非确定性因素的描述,支持业务流程的动态层次描述以及组织机构的变化,极大地增加了工作流管理系统的柔性和可扩展性
By object - oriented technic , the main matter , constructing , expression , class frame of field common data model ( fcdm ) and constructing technics liking entity definition , attributes , constraint rules . the object state transform rule and object based on conceptual cluster - role mechanism ( ccrm ) are importantly proposed 作者用面向对象技术给出了领域公共数据模型fcdm ( fieldscommondatamodel )的主要内容、建立与表达、类结构组织和实体定义、属性、约束规则等构筑技术,并重点介绍了对象状态转换规则和对象聚类机制及其特点。
