试论广播电视频率数据库的设计方法

Design Method of Radio and Television Frequency Information Database

数据库系统通常规模庞大且结构复杂,因此数据库设计是一种系统性、逻辑性较强的工作,数据库系统设计的优劣往往直接影响系统的整体性能。广播电视频率数据具有数量大、类型多、属性多样、关联关系复杂等特点,因此在设计频率数据库时应具有其特殊性。本文旨在以广播电视频率数据优选分析数据库的设计实现为例,结合广播电视频率数据的基本特点,分析探讨应用于广播电视频率数据的数据库设计方法。

Database system usually contains large number of records and complex structure, therefore database design is a systematic and logical practice.The design often directly affects the overall performance of the system. Radio and television frequency data have several characteristics such as large quantity, varied types, various attributes and complex relationships, so there would be a particular process of designing frequency database. This paper aims to take the design process of radio and television frequency data analysis system as an example to critically discuss the idea of designing database used for radio and television information in application.
