摘要
在需求不明确的情况下,用传统的数据库设计方法组织数据比较困难,数据层次性较差,且无法设计出一个通用的库,造成设计周期长、代码不易重用等问题,针对该问题提出一种新的基于树的数据库设计方法,该方法简单、直观、易于数据的组织,提高数据库设计的灵活性和通用性,在水库移民补偿金信息管理系统中得到较好的应用。
It is difficult to organize data by using traditional database design method when the requirement is uncertain. Traditional database design method has insufficient support for describing the level relation between or among data. The issues associated with designing and implementing a flexible and efficient information management system are not adequately addressed. This paper presents a novel database design approach which is based on tree structure. The intuitional description for data level makes it simple and pellucid. The flexibility and versatility of the approach provide not only reuse of database but also reuse of software architecture. The well use in the information management system for reservoir immigration compensation shows that the design method is feasible.
