The Design and Implementation of the Model Base System Based on the Hierarchical Model

As the hierarchical model belongs to the graphical model, operation and management will be inconvenient if stored in the form of a graphical file. In this paper, a new way is put forward in which the hierarchical model can be represented and stored via the database table. So a common model base system is designed. It implemented to make users achieve desired results without programming changes. When calling or safeguarding the model, they only need to operate the interface visualization. At the end, the correctness and practicability of this system is proved with AHP as an example.
