摘要:
研究了函数依赖集在属性子集上投影的理论问题.在此基础上开发了算法,成功地利用消元法解决了函数依赖集在属性子集上投影的计算问题,对于数据库模式设计有一定的参考价值.
Abstract:
An extensive research was made about the projection of FDs onto attributes. Some feasible methods and theory are advanced to solve the problem,and thereupon a practical algorithm is presented,which will exert a considerable influence on the programming of database design.
