Application and development of CAD/CAM (3)

Database Management System: On CAD/CAM systems, almost all applications are inseparable from the database. Improving the integration of CAD/CAM systems depends primarily on the level of the database. So choosing the right database management system has a great impact on CAD/CAM. Currently popular database management systems are: FOXBASE, FOXPRO, ORACLE, INGRES, INFORMIX, SYBASE and so on. The distributed database has the distributed INGRES version of INGRES/STAR of American Relational Technology Corporation, and the distributed ORACLE version of SQL*STAR introduced by ORACLE.

Computer network working software: Network workstation CAD/CAM system will become one of the main environments in the future, so network system software with strong functions is indispensable. The most typical network software is NOVELL's NET-WARE.

3. Application software application software is software developed on the basis of system software and supporting software for a specific application field. Therefore, this type of software is rich in content and rich in content. It is also the most invested in the research and development of CAD/CAM system construction. Because it is particularly targeted, there are not many commercialized software, and the price is particularly expensive. This work is also known as "secondary development."

Third, the future development

From the rise to the present, CAD/CAM technology has developed into an emerging industry. In some advanced countries, it has formed a complete high-tech industry from research and development, manufacturing, promotion and application to sales and service. According to statistics, the average annual growth rate of the CAD/CAM market in the United States has exceeded 15% in the past decade, which is significantly higher than the growth rate of other industries. In 1989, the National Academy of Engineering of the United States evaluated the 10 most outstanding engineering and technical achievements of humans in 25 years (1965-1989), showing that the development and application of CAD/CAM technology ranked fourth. In China, the development of CAD/CAM has become a common consensus among governments, enterprises and research institutions. The country has developed a vision for CAD/CAM development. In 2000, the penetration rate and coverage rate of CAD technology in major industries reached more than 70%. In this way, it is necessary to cultivate more than 100,000 CAD research and development talents, more than 500,000 operational and applied talents, and more than 2.5 million popular talents.
