The data structure of data removed from a database may be stored with the removed data. The removed data may be restored to the same or different data structure. Identifying information about the removed data may be stored. An attribute tag that identifies the collection of the data within the database may be associated with each removed data element. A removed data element may be restored to the database by comparing the attribute tag of the removed data element with the attribute tags in the current data structure and adding the data element to the database as indicated by the corresponding attribute tag. |
