Abstract: DEST system we built is an object-oriented expert system tool, where hash binary tree is implemented as inner data structure of object knowledge base. The basic structure and feature to represent frames, methods and rules by hash binary tree are pre-sented, as well as the characteristic of object represented by the binary tree.
