Open Server Server-Library/C is used to design servers that take advantage a client/server architecture. These Open Servers access data stored in non-Sybase database management systems, trigger external events, and respond to Open Client applications.
The client/server architecture divides the work of computing between “clients” and “servers”:
Clients make requests of servers and process the servers’ responses.
Servers respond to requests and return data, parameters, and status information to clients.
In this architecture, an Open Client application program is a client, using the services provided by Adaptive Server and Open Server. Using Server-Library, you can create a complete, standalone server.
