Three-layer architecture
1. Connect to the server in real time and store data on the server in a centralized manner. All clients can only connect to the server to call server data. Ensure that 200 people can run smoothly online.
Ii. functions:
1. Take the "employee database" in the "MSSQL sample data training" pubs as an example to add, delete, modify, and query data.
2. The client can manage online users and query user IDs, user names, computer IP addresses, computer names, logon times, and departure times to kill an online user.
3. servers with fixed IP addresses can also be used for parsing without fixed IP addresses using peanut shells.
3. The client business module uses DLL to call the module DLL by the EXE file.
