DirectConnect is Open Server™-based software that supports Client-Library,™ and Open Database Connectivity (ODBC) application programming interfaces (APIs).
Applications built on the Open Server API depend on
a specific directory structure environment and routing tables. For
an explanation of the installed directory structure, see the “Directory
structure” section in the specific chapter for your DirectConnect
product.
DirectConnect serves as a fundamental building block for highly-scalable database middleware applications. DirectConnect products are local area network (LAN)-based middleware servers that provide access to non-Sybase data and applications.
In addition, DirectConnect can be used with other Sybase products, such as Adaptive Server Enterprise/Component Integrated Services (ASE/CIS), Sybase Adaptive Server, and Replication Server.
DirectConnect consists of:
A server, which provides the framework in which service libraries can operate
One or more service libraries, which provide the framework in which access services can operate
One or more access services per service library, which are the logical points of connection for DirectConnect clients
The following subsections describe each of these components.
