| Abstract: | This paper presents an object-oriented information modeling method named object-relationship diagram(O-R diagram for short) based on the analysis of various informationmodeling methods.This method can be used to build the object-oriented model. The main elements of the O-R diagram and the procedure to build it are then described in detail. Two important kinds of Abstract relationship in the O-R diagram are introduced. Finally, the method of usingthe O-R diagram to build object-oriented product definition model is proposed. |
