    摘要: Techniques for undropping objects (e.g., tables) and dependent objects in a database systems are provided. When an object is dropped, the object is moved to a recycle bin where it resides until the user undrops the objects or the object is purged. Dependent objects are also moved into the recycle bin with the object to which they depend. The object can be purged from the recycle bin explicitly by a user or when more storage space is needed. Purging of dependent objects and partitions can be deferred if not required to obtain more storage space.

    摘要: A system for managing dropped objects of a database. The system comprises a finite amount of disk space for temporarily storing the dropped objects. The system further includes an indexer for assigning time stamps to each of the dropped objects and a reclaimer for reclaiming the dropped objects based on their time stamps. These time stamps can also be used to guarantee the amount of time the object remains in the recycle bin.
