Asynchronous real-time retrieval of data

摘要

A data retrieval system includes a gateway server and an access client. The gateway server is communicatively connected to the access client through a network. The gateway server provides a presentation service (PS) and a real-time service (RTS), which cooperate with the access client to retrieve data from a data store and then provide the retrieved data to a user's remote communication device. More particularly, when a user wishes to retrieve data from the data store or to send data to the data store, the user establishes a communication connection between his or her remote communication device and the gateway server, and then requests the desired data from the gateway server. In response, the gateway server sends a command to the access client, instructing it to retrieve the requested data. The access client retrieves the requested data from the data store, and returns the retrieved data to the gateway server. The gateway server then relays the requested information back to the user's remote communication device.

1. A server system for controlling operation of a computing device, the computing device comprising a client component, the client component being a client of the server system, the server system comprising:
one or more communications interfaces; and one or more processor units configured to cooperate with the one or more communications interfaces in order to:
receive, at the server system, a request to perform an action;establish a data communications session between the server system and the computing device comprising two-way communications between the server system and the computing device via a data channel by sending a first command from the server system to the computing device via a one-way communication connection, the one-way communication connection being separate from the data channel; send, during the data communications session, a second command from the server system to the client component of the computing device, the second command being configured to cause the computing device to perform the action; and
receive, at the server system, data relating to the action from the computing device via the data channel.
