Any client application that uses ASE must establish a connection to that server before any work can be done. The connection forms a channel through which all activity from the client application takes place. For example, your user ID determines permissions to carry out actions on the database—and the database server has your user ID because it is part of the request to establish a connection.
The ASE OLE DB Provider uses connection information included in the call from the client application, perhaps together with information held on disk in an initialization file, to locate and connect to an ASE server running the required database.
