System and method for automatically selecting a data source for providing data related to a query

A computer-implemented method of prioritizing a predefined set of electronic data sources includes the steps of electronically determining data sources in which at least one of one or more source fields is the same as a query data item of a query statement, electronically and dynamically ranking the data sources in which at least one of the one or more source fields is the same as the query data item based on at least the ability of the data sources to provide data at one or more query dimensions of the query statement and the extent of aggregation necessary to provide the data, and electronically identifying one or more of the data sources having the highest rank as preferred data sources for locating the data value.
