In recent years, the expansion of business organizations, service stations have increased the number of auto repair plants, and their functions have not kept pace; the number of interlocked sales departments has increased, and dial-up communications on external networks have been interrupted frequently, resulting in errors in business data; cyber virus attacks and operations have been threatened. Urgent hard and software upgrades should be made.
The main content of the software upgrade is to increase the database system's operating interface and application software modules and the corresponding database, 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 Gigabit switches through a firewall and externally passed through Gigabit switches and optical fibers. The internal three-layer gigabit switches and optical fibers are connected to the Intranet via a firewall. Several hundred megabytes of switches are forwarded to each user; at the same time, the internal telephone network of the enterprise is connected to a three-tier gigabit switch via VDSL switches.
1. Due to the increase of organization and the expansion of business scope, new function modules of database application software should be added to maintain the original more than 50 databases and 20 temporary databases. For some databases, fields and index files should be added to accommodate the new modules. Needs and inquiries are required to increase the plan, accounts receivable, payables, inventory analysis, inventory loss, taxation, auto repair factory settlement and other modules on the basis of the original.
2, the original auto parts database system has the following problems: First of all, the database query key word is the auto parts spare part number. Due to the large number of manufacturers, the same auto parts and accessories are in a one-to-one relationship, but the same name and part number are in a one-to-many relationship. This requires operators to familiarize themselves with backing more than 10,000 spare parts in order to work on the job. Today's large labor mobility is a problem.
