What is a client-server concept?
An ERP system is ultimately a large network that can be accessed by different users from their workstations. In order to ensure collaboration and data exchange and to distribute tasks in this network, the structure of such a system follows the so-called "client-server model": The client (as "customer") requests certain tasks ("services") from the server. The server (as "supplier" so to speak) makes these services available, usually for several clients at the same time. The server is thus nothing more than a program that communicates with the client and offers services.
