<p>The invention provides users a simplified view of information stored in, and across, all of their operational systems, which may include data warehouses/marts, relational and non-relational databases and text sources. This enables users to query quickly and easily any cross-enterprise data source for up-to-the-minute information. It allows them access to current information in real-time, regardless of where the data resides. Embodiments of the invention allow users make queries through their web browser and receive immediate, direct, simultaneous access to information from multiple ERP systems, proprietary databases, strategic extranets and the Internet. The invention transposes data formats from different databases into a common format, enabling users to access and use information from different, incompatible databases simultaneously. Scenarios can be saved in the server and integrated into any Internet/Intranet application. As such, the invention integrates business data from incompatible systems, without creating an additional data store. Embodiments of the invention include an object-oriented data retrieval system for retrieving data from a plurality of external data sources. The object-oriented data retrieval system includes a category object encoded in an object-oriented programming language. In embodiments of the invention, the category object may contain a plurality of meta fields and at least one function for ordering data in the plurality of meta fields. The system also contains a plurality of transposed objects encoded in the object-oriented programming language, which contain functions for mapping fields from the plurality of relational data sources to the plurality of meta fields.</p> |
