摘要
A method, system, and computer program product for managing database records with attributes located in multiple registries are disclosed. A data processing system identifies one or more attributes of a record to be accessed from one or more of a plurality of distributed databases, wherein a first attribute among the one or more attributes resides in an unknown database among the plurality of databases and it is known that a second attribute resides in a particular database among the plurality of databases. The data processing system forms a query, which includes a request for the first attribute and a request for the second attribute, and sends the query to the particular database. The data processing system receives a positive response to the query indicating that the particular database contains the first attribute for the record, and in response to receiving the positive response, the data processing system stores an identifier of the particular database in association with the first attribute. The data processing system then accesses the first attribute and the second attribute of the record in the particular database.
