When it comes to databases, I don't think we have to talk about the data structure first. In 1996, when I first went to college to study computer programming, the teacher told us: ComputerProgram= Data Structure +Algorithm. Although the current development of programs has gradually transitioned from process-oriented to object-oriented, I strongly agree with the formula that the teacher told us eight years ago: computer programs = data structures + algorithms. The first thing to do in object-orie

Since the early 80, many computer experts in China have been digging into large enterprises, trying to develop the ideal large-scale mis. Practice has proved that the large number of mis developed, most is not very ideal. Why? According to author further reseach, one of the important reasons is that the database design of MIS is not paid enough attention in the development process, and it is not treated as
