1. A system for optimizing data queries for related records in a reliable fashion, having a first computing device communicatively coupled with a second and a third computing device, and communicatively coupled to a first database that stores real-world entity data, having said second computing device communicatively coupled with said first and said third computing device, and communicatively coupled to a second database that stores real-world entity data, having said third computing device communicatively coupled with said first and said second computing device, and communicatively coupled to a third database that stores real-world entity data, comprising: a hierarchical system of Consolidation Strings for said first database, wherein each Consolidation String in said hierarchical system represents one or more key pieces of information relating to a real-world entity stored in said first database, wherein the information represented in each Consolidation String is in a character format, and wherein the hierarchical ranking of Consolidation String priorities are used to optimize database queries to find matching records for at least one entity of interest with substantial certainty; a hierarchical system of Consolidation Strings for said second database, wherein each Consolidation String in said hierarchical system represents one or more key pieces of information relating to a real-world entity stored in said second database, wherein the information represented in each Consolidation String is in a character format, and wherein the hierarchical ranking of Consolidation String priorities are used to optimize database queries to find matching records for at least one entity of interest with substantial certainty; a hierarchical system of Consolidation Strings for said third database, wherein each Consolidation String in said hierarchical system represents one or more key pieces of information relating to a real-world entity stored in said third database, wherein the information represented in each Consolidation String is in a character format, and wherein the hierarchical ranking of Consolidation String priorities are used to optimize database queries to find matching records for at least one entity of interest with substantial certainty; the capability of said first computing device to query said first database and cause said first database to also query said second and third databases, wherein an entity-record match between said first and second databases will be found and said matching entity records are consolidated from an end-user's point of view, if a pair of entity records have Consolidation Strings on the same priority level that are character-wise identical, and wherein an entity-record match between said first and third databases will be found and said matching entity records are consolidated from an end-user's point of view, if a pair of entity records have Consolidation Strings on the same priority level that are character-wise identical; the capability of said second computing device to query said second database and cause said second database to also query said first and third databases, wherein an entity-record match between said second and first databases will be found and said matching entity records are consolidated from an end-user's point of view, if a pair of entity records have Consolidation Strings on the same priority level that are character-wise identical, and wherein an entity-record match between said second and third databases will be found and said matching entity records are consolidated from an end-user's point of view, if a pair of entity records have Consolidation Strings on the same priority level that are character-wise identical; and the capability of said third computing device to query said third database and cause said third database to also query said first and second databases, wherein an entity-record match between said third and first databases will be found and said matching entity records are consolidated from an end-user's point of view, if a pair of entity records have Consolidation Strings on the same priority level that are character-wise identical, and wherein an entity-record match between said third and second databases will be found and said matching entity records are consolidated from an end-user's point of view, if a pair of entity records have Consolidation Strings on the same priority level that are character-wise identical.
2. The system for optimizing data queries of claim 1 , wherein: the highest-ranked Consolidation Strings are based on positive identifiers; the intermediate-ranked Consolidation Strings are based on demographic information; and the lowest-ranked Consolidation Strings are based on associative information that spans multiple-entity types.
