Disclosed is a system for, and method of, identifying a universal entity representation in an electronic universal database that corresponds to a foreign entity representation in an electronic foreign database, each entity representation including a plurality of linked records, each record including a plurality of fields, each field capable of containing a field value, each field value associated with a field value weight. The system and method include constructing a plurality of field match templates, wherein at least one field match template comprises a fixed field portion, an optional field portion, and an extra-credit field portion, the fixed field portion designating at least one field of a record as fixed, the optional field portion designating at least one field of a record as optional, the extra-credit field portion designating at least one field of a record as extra-credit, wherein an arbitrary record is considered to match an arbitrary query if a fixed field of the arbitrary record is populated with a field value that matches a corresponding fixed field value of the arbitrary query and an optional field of the arbitrary record is populated with one of a null field value and a field value that matches a corresponding optional field value of the arbitrary query. The system and method also providing a plurality of distributed tables, each distributed table being associated with a field match template and storing a plurality of records sorted in a list according to a plurality of fields of the field match template, wherein each record is associated with one or more entity representations. The system and method further include receiving, using a computing apparatus, a query identifying or constraining a plurality of field values, the query associated with a record in the foreign database. The system and method further include comparing, using a computing apparatus, the query to a plurality of field values of the plurality of fields of the plurality of distributed tables to identify an entity representation in the universal database that corresponds to the query based on field designations specified by the field match template. The system and method even further include outputting, using a computing apparatus, an identifier for the identified entity representation.
