Research And Application Of OOA/OOD Method In MIS

This thesis discusses some essential problems of software development, states objec oriented idea and method in terms of philosophy. According to the features of MIS, this article summarizes some rules of it, finds some problems which exists in MIS development used OOA and OOD, and gives corresponding methods to them. The concept of function class group and interaction class group is also presented for the purpose of raising the utility of objet oriented development method. Programmers can realize the division of functions and interfaces of MIS and raise flexibility and resusability of software system by using that concept. On the basis of study on lots of things, this thesis concludes that things of the objective problem domain have four states in their evolution which are birth, activity, sleep and death. Two kinds of OOD methods to function class group are also given , including OOD method based on two-dimensional data table and OOD method based on object.
