Method and system for asynchronous correlation of data entries in spatially separated instances of heterogeneous databases

A non-transitory, computer-readable storage medium storing one or more executable instructions that, when executed by at least one processor, causes the at least one processor to:

• query a first user information database on a first server for a piece of user information, wherein the first user information database comprises a user profile that includes an initial piece of user information corresponding to a user, and wherein the initial piece of user information includes at least user identification data from a session;
• responsive to not identifying the piece of user information in the first user information database, query a second user information database stored on a second server for the piece of user information associated with the initial piece of user information;
• and
• retrieve the piece of user information from the second database and update the user profile by storing the piece of user information and an identity of the second user information database to the user profile of the first user information database.

A system comprising:

• a first server in communication with a first computing system including a first memory and at least one processor;
• and
• a second server in communication with a second computing system, the second computing system including a second memory and a second processor, the second server in communication with the first server;
• wherein the first memory comprises program instructions executable by the at least one processor of the first computing system to:
• query a first user information database on the first server for a piece of user information, wherein the first user information database comprises a user profile that includes an initial piece of user information corresponding to a user, and wherein the initial piece of user information includes at least user identification data from a session;
• responsive to not identifying the piece of user information in the first user information database, query a second user information database stored on the second server for the piece of user information associated with the initial piece of user information;
• retrieve the piece of user information from the second database and update the user profile by storing the piece of user information and an identity of the second user information database to the user profile of the first user information database;
• determine a likelihood that the piece of user information corresponds to the user;
• compare the likelihood to a predetermined threshold;
• and
• provide at least a portion of the updated user profile associated with the piece of user information to a requestor when the likelihood that the piece of user information corresponds to the user exceeds the predetermined threshold based on the comparison.
