Open Client provides three application programming interfaces (APIs), named dblib and ctlib, and Net-Library.These products enable communications between Adaptive Server® Enterprise and Open Server applications and 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 (except for DB-Library™), allow communications with clients and other servers. In addition, Open Server provides routines to:
Handle multiple client connections
Schedule interactions with clients
Handle error conditions
Perform other functions required from a server
