A computer-implemented method for associating information related to an entity stored in a secondary data store with information related to the entity stored in a primary data store, the method comprising: identifying an entry in a primary data store that contains information related to an entity; receiving a request to associate an entry in a secondary data store with the identified entry in the primary data store; identifying information in the secondary data store that identifies the entry in the secondary data store; and associating the identified information with the entry in the primary data store, so that the entries from the primary and secondary data store can be viewed together without modifying the secondary data store.
