1. The Evolution of Information Technology and Enterprise Electronicization Over the past 20 years, the development of information technology has grown by leaps and bounds. From the 1970s to the main computer, and to the widespread use of micro-computers in the 1980s, the 90s entered the Client-server combination and the e-commerce started in 2000. The rapid development of information technology is unimaginable. In fact, the process of enterprise electronicization is an evolutionary process, as shown in the figure below.

1) The evolution of computer software from generalization to professional or industrialization. Early computer systems were mainly used for data processing such as accounting, document printing, and order processing. Commercial software at the time was highly versatile, for example accounting software could be used in various industrial industries. The computer integrated manufacturing system that began in the late 1980s focused on helping manufacturers increase productivity and provide Ualue-added services to their manufacturers. The corresponding commercial software must be professional, such as production scheduling. At the same time, software developers must have a fairly deep understanding of the industry and may not be able to do so in another industry. Successful industry software developers have a fairly deep knowledge of the industry's production and management.
2) The integration and reintegration of computer integrated manufacturing systems are different from the earlier data processing systems in terms of their information integration capabilities. With the rapid development of computer hardware and software, the degree of information integration has reached a criss-cross and well-ordered stage.
In general, there are three levels of integration:
Business Process Integration: Integration of various departments within the company. For example, the integration of information and decision-making in various departments such as product design, order entry, and production scheduling.
Production process integration: This is the integration of various departments within the company with the production line control system to form orders, schedules, and production trains. From the order input to the production schedule, to the machine controller's automatic information transfer and conversion process. The whole process can be completed within minutes, and the entire delivery cycle is only a few hours.
External Integration: This is the integration of the internal departments of the company with the external systems of the company (customers, suppliers). E-Commer is an integrated tool that forms the basis for customers, warehouses, and factories. Customers can check the progress of each order via the Internet, such as order entry, production, inventory, delivery, billing records, etc. Customers are looking at the records of different departments of the company, and all information inquiry and exchange is a matter of effort. Extranet, a tool for different companies to share information through the Internet, makes it possible for customers to provide comprehensive services and help them achieve their business goals. The popularity of the Internet has also made operating costs popular. (Wang Ming Wang Zhixing)
