数据库工程设计

摘要

It is a hard and complicated task to build a database for a great data processing system. Executing software engineering in the database design is an important method of database design. According to the common rule and method of software engineering, the problems which should be considered in the database engineering design have been analyzed combined with the characteristics and requirement of database system. And then, the requirements for building data schema have been suggested. The main contents, methods and approaches for database engineering design have also been discussed and put forward based on the basic task and standard of life cycle of software engineering in every phase.%为一个大型的数据处理系统建立数据库是一项艰巨而复杂的任务。在数据库的设计中实施软件工程是数据库设计的重要方法。根据软件工程的一般规律和方法并结合数据库系统本身的特点与要求，分析在数据库工程设计中应考虑的问题，提出建立数据模式的基本要求，并依据软件工程生存周期各阶段的基本任务和标准，提出数据库工程设计的主要内容、方法和步骤。
