Abstract: 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.

Key words: tree structure, database based on tree, reservoir immigration compensation calculation
