Abstract

A computer-implemented method of prioritizing a predefined set of electronic data sources, including the steps of: providing a database containing metadata related to the predefined set of electronic data sources, the metadata comprising, for each electronic data source, one or more source data items and one or more source dimensions; electronically receiving first signals at a processor, the first signals related to a query for a data value; electronically identifying a query data item and one or more query dimensions based on the query; electronically determining the data sources in which at least one of the one or more source data items is the same as the query data item; for each of the data sources in which at least one of the one or more source data items is the same as the query data item, electronically assigning a score to the data source based on at least the ability of the data source to provide data at the one or more query dimensions and the extent of aggregation necessary to provide the data; electronically and dynamically ranking the data sources based on the assigned scores; and electronically identifying one or more of the data sources having the highest rank as preferred data sources for locating the data value.
