constraint n. 1.強迫,拘束。 2.約束,壓抑,拘泥。 3.強制力。 4.緊張感[狀態]。 by constraint 勉強,強迫。 feel constraint覺得局促不安,感受壓迫。 show constraint顯得局促。 under [in] constraint 被迫,不得不;被束縛著。
Object allows you to define foreign - key constraint rules 對象還允許定義外鍵約束規則。
Foreign - key constraint rule 外鍵約束規則
Columns that are defined with constraints follow constraint rules regardless of this setting 使用約束定義的列都將遵循約束規則,而與此設置無關。
Gets or sets a value indicating whether constraint rules are followed when attempting any update operation 獲取或設置一個值,該值指示在嘗試執行任何更新操作時是否遵循約束規則。
Under the background of packing design of bender , the packing algorithm of gradual advancement based on engineering - oriented constraint rule is presented 摘要以彎管機布局設計為背景提出了一種基于工程約束規則的層次推進布局算法。
Moreover , we accelerate solution of packing problem to make packing result accord with actual requirement by applying engineering - oriented constraint rule to packing 同時,在布局過程中引進了工程約束規則,加快了布局問題的求解,布局結果更符合實際要求。
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 將基因遺傳/禁忌混合算法應用于加工工序的聚合問題,以工序聚合中的約束規則為基礎,建立了摘要遺傳算法的適應度函數,通過實例驗證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 為支持流程中不確定性因素和動態因素的描述,提出了柔性工作流的動態層次描述方法,使得流程設計人員在流程定義階段定義的主流程可以在任意時刻由子組織的負責人進行細化和擴充.為保證動態層次描述的正確性和完整性,討論了動態層次描述的一系列約束規則,確保分解后的流程與原有流程實現無縫銜接.該描述方法支持對不可預知的非確定性因素的描述,支持業務流程的動態層次描述以及組織機構的變化,極大地增加了工作流管理系統的柔性和可擴展性
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 作者用面向對象技術給出了領域公共數據模型fcdm ( fieldscommondatamodel )的主要內容、建立與表達、類結構組織和實體定義、屬性、約束規則等構筑技術,并重點介紹了對象狀態轉換規則和對象聚類機制及其特點。
