The MULTI-SOURCE, MULTI-DIMENSIONAL, CROSS-ENTITY, MULTIMEDIA MERCHANT ANALYTICS DATABASE PLATFORM APPARATUSES, METHODS AND SYSTEMS (“MDB”) transform data aggregated from various computer resources using MDB components into updated entity profiles and/or social graphs. In one implementation, the MDB aggregates data records including search results, purchase transaction data, service usage data, service enrollment data, and social data. The MDB identifies data field types within the data records and their associated data values. From the data field types and their associated data values, the MDB identifies an entity. The MDB generates correlations of the entity to other entities identifiable from the data field types and their associated data values. The MDB also associates attributes to the entity by drawing inferences related to the entity from the data field types and their associated data values. Using the generated correlations and associated attributes, the MDB generates an updated profile and social graph of the entity. The MDB provides the updated profile and social graph for an automated web form filling request.
