Federated search of relational data sources allows the NIF system to take advantage of the schema registration process. Since the schema is registered, it is easier to design the result page to show meaningful tables and columns. It also allows the result designer to choose output data in such a way that the database results can be hyperlinked to the original data records and to any web-accessible tools exposed by the data sources. For SUMSDB, the NIF search on “hippocampus” leads to the display of the brain surfaces in the WebCaret tool.
