Part III: Programming with ADO > Connection Objects

Chapter 12. Connection Objects

The top level of the ADO object model is the connection object, which describes the access to an OLE DB provider. The client establishes a connection to a server by using the user-entered data to search the network for the server and to log on. The connection can be used to exchange data in both directions. It is possible for a client to maintain multiple connections to a server that can be used to transmit data simultaneously and in parallel, if needed. Every connection requires resources on the client and the server, so normally the system tries to minimize the number of connections.

The Connection object describes the connection between the client and the server. Tables 12-1 through 12-3 list all of the properties, methods, and events related to the Connection object.
