标准摘要
[中文适用范围]: ISO/IEC 13249 定义了多媒体和应用领域中使用的各种数据通用的许多通用数据类型包,以便能够在 SQL 数据库中存储和操作这些数据。 每个主题领域中的包都被定义为 ISO/IEC 13249 的一部分。 ISO/IEC 13249 的这一部分定义了 ISO/IEC 13249 的两个或多个其他部分所共有的概念、符号和约定。 特别是,它描述了 ISO/IEC 9075 在 ISO/IEC 13249 的其他部分中使用的方式来定义用户定义的类型及其适合每个主题领域的行为。 [外文原描述]: ISO/IEC 13249 defines a number of packages of generic data types common to various kinds of data used in multimedia and application areas, to enable that data to be stored and manipulated in an SQL database. The package in each subject area is defined as a part of ISO/IEC 13249. ISO/IEC 13249-1:2007 defines those concepts, notations and conventions that are common to two or more other parts of ISO/IEC 13249. In particular, it describes the way ISO/IEC 9075 is used in other parts of ISO/IEC 13249 to define the user-defined types and their behaviour appropriate to each subject area.
