In recent years, the expansion of corporate organizations, the addition of auto repair shops to service stations, and the lack of functions; the increase in interlocking sales departments, and the frequent interruption of external network dial-up communications, resulting in business data errors; network virus attacks, operations are threatened , Hardware and software upgrades should be urgently carried out.
The main content of the software upgrade is to increase the operation interface and application software modules of the database system and the corresponding database and index files, and modify the structure of the original database. The Web server, mail server, and database server of the intranet network are connected to the Internet metropolitan area network through the Gigabit switch and optical fiber through the two-layer Gigabit switch and the firewall; and are connected to the intranet through the three-layer Gigabit switch and optical fiber through the firewall. After several 100M switches of the company are transferred to each user; at the same time, the internal telephone network of the enterprise is connected to the three-layer Gigabit switch through the VDSL switch.
1. Due to the increase of organizational structure and the expansion of business scope, new functional modules of database application software should be added, and more than 50 databases and 20 temporary databases should be maintained. For some databases, fields and index files should be added to adapt to the new modules. For needs and query requirements, modules such as planning, accounts receivable, accounts payable, inventory analysis, inventory reporting, taxation, auto repair factory settlement, etc., are added to the original basis.
2. The original auto parts database system has the following problems: First, the key word for the database query is the auto parts spare part number. Due to the large number of manufacturers, there is a one-to-one relationship between the same auto part number and the part name, but the same name and part number are one-to-many. This requires operators to learn more than 10,000 spare part numbers before they can work. Today, labor mobility is a problem.
