Open Client architecture


Open Client can be thought of as comprising two components: programming interfaces and network services.

Client Library and DB-Library 

Open Client provides two core programming interfaces for writing client applications: DB-Library and Client-Library.

Open Client DB-Library provides support for older Open Client applications, and is a completely separate programming interface from Client-Library. DB-Library is documented in the Open Client DB-Library/C Reference Manual, provided with the Sybase Open Client product.

Client-Library programs also depend on CS-Library, which provides routines that are used in both Client-Library and Server-Library applications. Client-Library applications can also use routines from Bulk-Library to facilitate high-speed data transfer.

Both CS-Library and Bulk-Library are included in the Sybase Open Client, available separately.

Network services 

Open Client network services include Sybase Net-Library, which provides support for specific network protocols such as TCP/IP and DECnet. The Net-Library interface is invisible to application programmers. However, on some platforms, an application may need a different Net-Library driver for different system network configurations. Depending on your host platform, the Net-Library driver is specified either by the system's Sybase configuration or when you compile and link your programs.

Instructions for driver configuration can be found in the Open Client/Server Configuration Guide.

Instructions for building Client-Library programs can be found in the Open Client/Server Programmer's Supplement.
