Abstract: A computer-implemented information transfer method includes receiving a trigger message at a server, evaluating a selection rule to select a data flow to be presented to a user at an access device, and sending the data flow to an access device for pop-up presentation in response to the trigger. A server includes a database, a network interface, and a processor. The database includes a number of selection rules. Each selection rule includes instructions to select a data flow. The processor is operatively coupled to the network interface, the database, and the memory.

Abstract: A database access method includes receiving a data request at a switcher system from another computer, selecting a connection to a database system from among a collection of connections, and communicating with the database system across the selected connection to fulfill the data request. A computer program residing on a computer readable medium includes instructions for causing a computer to receive a data request from another computer, select a connection to a database system from among a number of connections to the database system, and communicate with the database system across the selected connection to fulfill the data request. A network of interconnected computing devices may include network elements configured by the computer program to implement the invention.
