Database Autonomy Service (DAS) provides the storage analysis feature. You can use this feature to view the storage usage of a database instance and the number of days for which the remaining storage space of the database instance is available. You can also view information about the usage, fragments, and anomaly diagnosis results of a tablespace in a database.
