constraint n. 1.強迫,拘束。 2.約束,壓抑,拘泥。 3.強制力。 4.緊張感[狀態(tài)]。 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(guī)則。
Foreign - key constraint rule 外鍵約束規(guī)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(guī)則,而與此設(shè)置無關(guān)。
Gets or sets a value indicating whether constraint rules are followed when attempting any update operation 獲取或設(shè)置一個值,該值指示在嘗試執(zhí)行任何更新操作時是否遵循約束規(guī)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(shè)計為背景提出了一種基于工程約束規(guī)則的層次推進(jìn)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(jìn)了工程約束規(guī)則,加快了布局問題的求解,布局結(jié)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(yīng)用于加工工序的聚合問題,以工序聚合中的約束規(guī)則為基礎(chǔ),建立了摘要遺傳算法的適應(yīng)度函數(shù),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(tài)因素的描述,提出了柔性工作流的動態(tài)層次描述方法,使得流程設(shè)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(fù)責(zé)人進(jìn)行細(xì)化和擴(kuò)充.為保證動態(tài)層次描述的正確性和完整性,討論了動態(tài)層次描述的一系列約束規(guī)則,確保分解后的流程與原有流程實現(xiàn)無縫銜接.該描述方法支持對不可預(yù)知的非確定性因素的描述,支持業(yè)務(wù)流程的動態(tài)層次描述以及組織機構(gòu)的變化,極大地增加了工作流管理系統(tǒng)的柔性和可擴(kuò)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?qū)ο蠹夹g(shù)給出了領(lǐng)域公共數(shù)據(jù)模型fcdm ( fieldscommondatamodel )的主要內(nèi)容、建立與表達(dá)、類結(jié)構(gòu)組織和實體定義、屬性、約束規(guī)則等構(gòu)筑技術(shù),并重點介紹了對象狀態(tài)轉(zhuǎn)換規(guī)則和對象聚類機制及其特點。
