Research And Development Of Integrated Highway Cad System Engineering Database

This paper, based on the analysis of the data of integrated CAD system of highway has built different data structure to store the system data and built a Link-Tree model to construct the database of plane design and vertical design. So this paper can manage the general engineering data, standard data and engineering data using VBS.O and the OOP technology, and has achieved the functions of sharing data, version control ect, which are the fundamental functions of engineering database.
