Abstract: The system creates a central UUID index mapping multiple local identifiers of multiple records in multiple databases to an identifier unique across the multiple databases including a first database without a UUID index. The first database includes a record having a first identifier. A second database includes an equivalent record having a second identifier different from the first identifier. The universally unique identifier in the central UUID index represents the first and the second identifier. The system receives a request from the first database to obtain an equivalent record from the second database, where the request includes an identifier of a record in the first database. The system determines that the identifier is a local identifier unique to the first database, based on the central UUID index. The system then converts the local identifier to the universally unique identifier, and sends the universally unique identifier to the first database.

Abstract: The disclosed system receives a request to establish a communication channel between a first system among the multiple systems and the second system among the multiple systems. The first system includes a first record with a first UUID unknown to the second system. The second system includes a second record associated with a second UUID unknown to the second system. The first record and the second record are equivalent. The system creates a UUID unique in the first and second systems. A first mapping between the UUID and the first UUID is stored in the first system and a second mapping between the UUID and the second UUID is stored in the second system. The system preserves security between the first system and the second system by enabling exchange of information associated with the first record and the second record across the communication channel using the UUID.
