Database Structure and Search Limitations
Data Structure Challenges When multiple databases merge into one system, the methods used to structure and query data directly impact search accuracy. A search for "ROBERT SMITH" may or may not return results for variations like ROBERT A, BOB, BOBBY, or ROBERTO—depending entirely on the database architecture. Whether separate queries must be made for each name variation differs significantly from one database provider to another, creating inconsistent search results across platforms.
Critical Considerations • Extraction technology often applied • Must ensure proper identifiers match • High risk of duplicated records • Should only be used as an initial pointer • All "hits" must be independently verified at the source
