The Study And Application Of Professional Automatic Graphical-base System

Since we enter the new century, computer technology has been widely used in all walks of life, in particular, the field of product development has therefore, brought about a new circle of technical innovation and with the increasing development of AutoCAD, concurrent graphics processing technology and the establishment of graph database have become new trendency for study.This system is intended to establish a set of special automatic graph database system on the basis of commercial graph software AutoCAD 2004 platform, which is suitable for shipbuilding and mechanical fields and the related information used in this system is based on the the special graphs as well as the modification to the original graphs that are specially used in the shipbuilding and mechanical fields. The graphs and data are stored in the form of database table ,which is very convenient to us. When we need to creat graphs or do some modified operation, we can directly index necessary data from the database and then execute those operations needed and finally , if necessary, store the processed data back to database . Design module is designed to process all the modification to the graphical information and is capable of accessing each data item in the graph and data structure and creat new graphs and delete old graphs according to the needs of the customers and establish customers' own graphs information base. The design process is a creative one during which, with the development of the design, the system is supposed to have the ability of processing complicated data structure and constructing data model which is capable of illustrating its design in more details, for example, the standard graphs which is often used in the design or former design results, and therefore, the index data process by programme-processing is very complex, at the same time, this system is also a intertive design environment in which the designer hope that the system can quickly response to all the operation requests given so as to modify and improve the original design.This system is intended to set up computer network by use of customer / server model and is operated on the Windows NT platform as well as execute unified adiministration of data storage by adoping SQL Server 2000 database and meanwhile the operation of the system needs the support from AutoCAD 2004 software platform and the Visual Basic 6.0 is mainly used for the development language, which is speciality used for the administration of AutoCAD's dual graphs, Excel's table file, Word's file and PowerPoint's demonstration paper etc.This system is in conformity with the national standard and thus, it can meet the actual requirements for operation in the shipbuilding and mechanical industry and it can also be widely spread to other relative industries and work units. It is sure to bring about great economical and socail benefit.
