The digital product and the electronic commerce integration concept design of the system structure of CATIA V5 version, but for the establishment of a whole process of product development work environment for the digital enterprise. In this environment, the simulation can be carried out on all aspects of the product development process, and can realize the electronic communication between engineers and non engineers. The whole process of product development from concept design, detailed design, engineering analysis, product definition and manufacturing and product use throughout the life cycle and maintenance. As the worlds leading CAD/CAM software, CATIA can help users to complete large to small aircraft to design and manufacture a screwdriver, which provide the ability to design and complete: from 2D to 3D to the technical index modeling, software system, as a fully integrated, CATIA mechanical design, engineering analysis and simulation and processing and other functions organically, to provide users with a strict no paper work environment so as to shorten the design time, improve the quality and reduce the cost effect. CATIA developed by the French Dassault, IBM company responsible for 6 the global sales and customer service technical support. The Dassault company since its establishment in 1981, now has more than 1300 employees, including software development engineer accounted for more than 900 people, has two times to launch new products every year, as the worlds largest CAD/CAM/CAE/PDM software developers. CATIA users in various field of automobile, aviation, shipbuilding, machinery manufacturing, household appliances in the world, more than 9000 users, the total number of 100000 set. To provide a strong guarantee Dassault strong financial backing for CATIA new product development, make the products and advanced function can source continuously being offered to users； IBM as the worlds largest manufacturer of computer information system, with its strong technical support strength, long known famous after sale service, help the many CATIA users the successful. IBM engineering solutions (Engineering Technology Solutions Unit-ETS) is a rich experience of the CATIA global professional technical support team. The team has more than 1000 CATIA engineer, they are to support global customers at the same time, will also be the needs of all walks of life and experience feedback to CATIA development department, so that CATIA users to quickly launched to meet the outstanding product today and future needs. IBM Greater China region of the ETS technical support team is stronger in the rapid development, IBM/ETS support team, and IBM CATIA agent together with Beijing, Shanghai, Guangzhou, Hongkong and Taipei as the center, to provide high quality and quick for the Greater China region CATIA user service. IBM was in Sydney with CATIA Asia Technical Support Center, provide free telephone consultation service for the Asia Pacific region of CATIA users. The CATIA software is designed by the French Dassault The Aerospace 7 Corporation from the beginning of the seventys development, and applied to the aerospace industry； eighty in the early 1980s, the Dassault group to set up a Dassault Systems company, technology development, responsible for CATIA, and CATIA as the business software market, and this also signed a contract with IBM, IBM is responsible for the CATIA global software technology service and support. CATIA is the only company in the world will open business software and computer manufacturers combined, and the IBM is responsible for the global support services and sales of products, which makes CATIA not only have a more solid background, but also allows customers to really be integrated complete scheme, as well as the first-class products, first-class service! As the worlds leading CAD/CAM software, CATIA has maintained a remarkable performance in the past twenty years, and continued to maintain a strong development trend. Steady growth in sales； CATIA dominance in the auto and auto, aerospace field increases ceaselessly, at the same time, CATIA also a lot into other sectors, such as locomotive manufacturing, general machinery, household appliances, ships etc. In China, CATIA also has made a great achievement, Harbin, Shenyang, Jingdezhen, Shanghai, Chengdu, Xian, Guiyang aircraft factory all have chosen CATIA as the core design software. Many of the FAW Group, FAW Volkswagen, Shenyang Jinbei, Shanghai Volkswagen, Beijing jeep, Wuhan Dragon, car companies have used CATIA to develop their new models, to improve their market competitiveness.
