航空发动机数据库关键问题的研究

RESEARCH ON KEY QUESTION OF AEROENGINE DATA BASE

成功建立数据库的关键是根据数据模型分析，研究结果进行数据库逻辑结构的设计。经过分析和研究，采用关系数据理论，使航空发动机、数据库具有合理的逻辑结构。

The key to setting up data base successfully is the design of data base logical structure according to the results of data model analyses and study.Through analyses and study,the reasonable logical structure of aeroengine data base can be achieved using relative data theory.
