Within the new items relation , adding the item element and setting its type to unnamed complextype , creates another relational table , which also appears on the design surface 在新的项关系内，添加项元素并将其类型设置为unnamed complextype时，将创建另一个关系表，它也将显示在设计图面上。
The connection information consists of parameters and corresponding values that the odbc driver manager uses to establish a connection . file restore an operation that restores one or more files of a database 一种数据库范例，将数据视为信息多维数据集（包含维度和按单元划分的汇总数据） ，而不是关系表和关系列。
The object - oriented data model is transformed to relationship data model by means of the translation of relationship tables in oodbms to conventionally data definition language in rdbms 在设计阶段，通过将面向对象中的关系表用传统关系数据库的数据定义语言来描述，从而实现了面向对象数据模型向关系型数据模型的转换。
By describing structural and semantic of relational table in a single xml document , resolve the problems of poor capability of a relational table in the case of describing semantic and structure information 采用xml作为数据集成的中间模式，将关系表的结构信息和语义信息表示在一个xml文档中，使得集成过程更加方便。
With the help of the desiign principle of standardized database , it concludes the approach how to eliminate transfer dependence on the correlative tables , and discusses the way of how to use entity - relationship ( e - r ) model to design the database 论文还通过范式及规范理论，推导了如何消除关系表中的传递依赖，并讨论了使用实体联系( e - r )模型设计数据库的方法。
As an easy - to - understand example , many different conceptual elements are rendered with italics in printed books . different books use different conventions , but any of the following docbook tags might be rendered in italics when actually typeset 例如，在一个结构中，两个实体通过一张关系表表示相互联系的多对多关系（例如，贷款应用中借方和资产） ，简单的xml父子关系是不够的。
Rather than supporting direct mapping of object - oriented classes and properties to relational tables and columns , the entity framework maps relational tables , columns , and foreign key constraints to entities and relationships in conceptual models 与直接将面向对象的类及其属性映射成关系型数据表和列不同，实体框架将数据库内的关系表、列以及外键约束映射成概念模型里的实体和关系。
The user is unaware that the information comes from diverse sources , such as relational tables , xml repositories , and business applications , which are often distributed across a range of geographic locations and a variety of operating system platforms 用户不会意识到信息来自于不同的源，如关系表、 xml存储库和业务应用程序，这些源往往是跨广泛的地理位置和多种操作系统平台分布的。
Users do not require any permissions to the relational tables in the underlying relational database from which analysis services loads its data , and do not require any file level permissions on the computer on which the instance of analysis services is running 用户不需要对基础关系数据库（ analysis services从该数据库加载其数据）中的关系表的任何权限，也不需要对运行analysis services实例的计算机的任何文件级别权限。
You can use the xml schema editor to perform tasks such as creating xml schema components , importing and viewing xml schemas , generating dtds and relational table definitions from xml schemas , and generating java beans for creating xml instances of an xml schema 您可以使用xml schema编辑器执行诸如创建xml模式组件，导入和查看xml模式，从xml模式生成dtd和关系表定义，以及生成用于创建xml模式的xml实例的java bean之类的任务。
