Abstract

A method and system for providing remote access to heterogeneous information sources from computing devices including but not limited to personal computers, laptop computers, PDAs, cellular telephones is presented. A middle-tier server is provided in a multi-tier environment for allowing a data-centric approach to accessing, modifying and updating content located at remote data sources. The middle-tier server provides functionality for a mobile (or similar) user to perform a search query, request for document and/or data, update remote data, and perform commands on remote data sources. In addition, the middle-tier server manages the authentication of the user in sessioned or sessionless mode. In particular, search query results are processed such that the results answer a search query. That is, rather than simply providing a list of document matches, the middle-tier server extracts information from the document that answers the search query most appropriately. Finally, the middle-tier server, using user preferences, device capabilities and settings, transforms the result, document or data into an appropriate format that is suitable for the device, user and communication network. This allows the user to easily process and view the document on a (possibly limited capacity/functionality) device.
