DIRECTED GRAPH BASED ASSOCIATION ALGEBRA FOR OBJECT-ORIENTED DATABASES

WU Shengli; WANG Nengbin(Department of Computer Science and Engineeing, Southeast University, Nanjing 210096)  
This paper presents directed graph based association algebra which is an important improvement of nondirected graph based association algebra worked outby S. Y. W. Su et al,and gives an algorithm for optimizing association algebraic expressions. Directed graph based association algebra can reflect more precisely theintrinsic quality of object-oriented models and has more advantage over query processing and optimization of objects than its nondirected graph based counterpart.
