US Patent 7783613 Context-aware middleware platform for client devices

Middleware can accept transaction requests from a client device and tailor the request to a backend transaction server. The server's response can be tailored to the client device. For example, characteristics of the client device such as screen real estate and supported functionality can be taken into account when generating a tailored response. Features such as caching can avoid repeatedly contacting the backend server. Pagination and column truncation can be supported. A transaction model can represent a transaction as device independent configuration information. The transaction model can be added or changed without coding. Useful for implementing an application across a wide range of devices transparently to the backend server.
