Abstract
Example embodiments provide various techniques for updating an old data structure configured to store metadata associated with database systems. In this method, a temporary data structure is created. Additionally, a new data structure representing an update of the old data structure is created. The metadata from the old data structure are copied to the temporary data structure, and the temporary data structure is transformed to match the new data structure. The metadata from the transformed temporary data structure are copied to the new data structure. The transformation of the temporary data structure instead of the old data structure may enable an application that is not being updated to be operational and to access the old data structure during the update. After the metadata is copied to the new data structure, a new version of the application is then able to access the new data structure.
