Abstract
A data search structure is provided for nearly instantaneous identification of one or more data records in a database. The data records are characterizable by two or more search parameters. The search structure includes two or more tables which list respective search parameters in a selected order. The tables also contain information that correlates associated search parameters among the tables. A data record key is provided to identify the particular data record corresponding to the search parameters. A method for constructing this search structure is described. Additionally, multiple methods for identifying groups of data records that satisfy a selected search criteria are also described.
