Open Client provides an application programming interface (API) and Net-Library, which allows communications between Adaptive Server Enterprise and Open Server applications, customer applications, third-party products, and other Sybase products.
Open Server provides the tools and interfaces needed to create custom servers. Like Open Client, a programming API and Net-Library enable communications with clients and other servers. In addition, Open Server provides routines that:
Handle multiple client connections
Schedule interactions with clients
Handle error conditions
Perform other functions required from a server
