A computer-implemented database and method providing an efficient, ordered reduced space representation of multi-dimensional data. The data values for each attribute are stored in a manner that provides an advantage in, for example, space usage and / or speed of access, such as in condensed form and / or sort order. Instances of each data value for an attribute are identified by instance elements, each of which is associated with one data value. Connectivity information is provided for each instance element that uniquely associates each instance element with a specific instance of a data value for another attribute. In accordance with one aspect of the invention, low cardinality fields (attributes) may be combined into a single field (referred to as a “combined field”) having values representing the various combinations of the original fields. In accordance with another aspect of the invention, the data values for several fields may be stored in a single value list (referred to as a “union column”). Still another aspect of the invention is to apply redundancy elimination techniques, utilizing in some cases union columns, possibly together with combined fields, in order to reduce the space needed to store the database.

A system and method for locating objects such as people, pets, and personal articles is described. A transceiver is attached to the person, animal, or item to be tracked and a handheld locator device is employed to transmit a locator signal containing an address code to the transceiver.

The invention disclosed herein concerns a data processing means for user tunable and selectable searching of a database wherein the data contained therein have associated descriptive properties capable of being expressed in numeric form. A quantized vector representative of the descriptive properties is created for each item in the database. This quantized vector becomes the fingerprint for each data item. The user submits a query item to be matched against the database for similarity. A fingerprint is calculated for the query item. The user may then assign weights to the individual descriptive properties based upon perceived importance. A newly weighted fingerprint for the query item is then compared with the weighted fingerprints for all the data in the database. A list of results sorted in order of decreasing similarity is presented to the user. The user may then change the previously assigned weights and then re-run the similarity search. This may be done as often as necessary to achieve the desired results. The invention describes similarity searching in a generic database. However, this invention is particularly desirable in databases containing chemical compound structure data or biological response screening result data. The process described herein may be run stand alone or as a preliminary screening search in a large database. If used for screening, it can greatly reduce the amount of data required for exactly matching a query item to the data in the database.
