The Metadb reporting database serves as a platform for generating reports for library staff on data from all functional areas of the FOLIO system. The Metadb software extracts, transforms, and loads data from the FOLIO application server continuously to the reporting database through its process of data synchronization. Both current and historical records are saved in tables in the reporting database. Some of these tables contain fields with patron identifiers, such as "user_id" and "requester_id." Patron identifiers are needed for current transactions – such as loans, requests, and fines that are open – to enable library staff to identify and communicate with those patrons. Patron identifiers for historical transactions – such as loans, requests, and fines that are closed – are not needed. To uphold the Cornell Library's Commitment to Privacy policies, patron identifiers on historical transaction records should be replaced with NULL values in the Metadb reporting database.
