many- 'meni BNC²³⁶²¹³⁺¹ 基本例句 adj.多;adv.大量;n.多数人西;大多数人;女名女子名;pron.许多人物 The case of the many- to- many associations is not discussed here, as its implementation is quite similar to the relations we presented before. 多对多关联的情况这里没有讨论,因为它的实现与我们前面介绍的大同小异。 ibm The kernel provides an abstraction called kernel keys, which map many- to- one onto hardware keys. 内核提供了一种称为内核键的抽象,它映射到多对一的硬件键。 ibm The purpose of this relation is to filter the many- to- many associations, which are handled by another relation. 此关联的目的是过滤掉多对多关联,它由另一个关联处理。 ibm Above, a many- to- one relationship is defined across a foreign key that is also part of a primary key. 在上例中,跨外键也是主键的一部分定义了多对一关系。 ibm However, when you try to represent a many- to- many relationship, this mechanism is insufficient, as each element may only have a single parent element. 但是,当试图表示多对多关系时,这种机制就不适合了,因为每个元素只有一个父元素。 ibm If a review of the frequency distributions for each source points to a many- to- one condition and one source has only unique values, then it is a likely reference source. 如果查看每个源的频率分布发现存在多对一的情况,并且一个源只有一个惟一的值,那么它很可能就是引用源。 ibm More than the simple mechanics of many- to- many relationships, I hope that you picked up on some of the subtleties of creating them as well. 除了简单的多对多关系以外,希望您还能从本文了解一些创建多对多关系的出色技巧。 ibm Most living organisms are so many- pointed they are blunt variations that happen to work, rather than precise renditions of proteins, genes, and organs. 多数生命体都是多指向的,因而它们是碰巧可行的硬生生的变种,而不是蛋白质、基因或器官的精确体现。 yeeyan See, the idea is, instead of many- many testing, you have many- standard and standard-many testing and you need radically fewer tests. 看到了吧,想法就是,不是多对多的去测试,而是多对标准,标准对多的去测试,你的测试少了可不止一点点。 cnbeta So, how do we map a many- to- many association? 那我们怎样映射多对多关系呢? cnblogs Survival is a many- pointed goal. 生存是一个多指向的目标。 yeeyan The intent is to ease the development process for building complex large many- screened applications. 它的目的就是简化构建复杂大型多页面应用程序的开发过程。 infoq There is a many- to- one relationship defined here, as shown above. 这里定义了一个多对一关系,如上面所示。 ibm These new walkways, however, were essentially a single conveyor moving from A to B, far simpler than the earlier many- ringed, multispeed systems with multiple points of entry and exit. 不过现在这些新的人行道实质上只是从 A到 B的简单的运输装置,远比早期多环道、多速度并带有多出入口的系统要简单。 yeeyan This is the classic example of a many- to-many relationship: Invoices may include many parts, and each part may appear on many invoices. 这是多对多关系的经典示例:发票可以包括许多零件,而每种零件可以出现在许多发票上。 ibm We created models for our feeds and associated them in a many- to- many relationship to an account. 我们已经为提要建立了模型并用多对多关系将这些模型与帐户关联了起来。 ibm You can define the many- to- one relationships among members within a dimension table as a separate dimension table, forming a hierarchy. 您可以将一个维度表中成员之间多对一的关系定义为一个单独的维度表,从而形成层次结构。 ibm You will probably have many- to- one relationships in your database. 您的数据库中很可能存在多对一的关系。 ibm |
