<p>Improved parameter-value databases and methods of using the same provide significant benefits to individuals loading data and/or conducting searches. In one aspect the database is used to properly identify overlap between search data and target data where the data sets contain any combination of single values, multiple values, and ranges. In another aspect items are loaded onto the database as sets of parameter-value pairs, with subsets of such pairs being further sub-correlated for various purposes, including establishing display order, chronological order, or coupling groupings of parameter-value pairs. In another aspect users are allowed to add new parameters to the database in such manner that the database develops a user-evolved categorization system. In yet another aspect users are presented with word or other value lists to assist them in searching the database, and the lists become smaller as filters are applied. The databases and methods are applicable to information that is not strictly marketplace information, namely opinion surveys, scientific information, legal information, and general information.</p> |
