Remove key/data pairs from the database. If key
            is DatabaseEntry, the key/data pair associated with 
            key is discarded from the database. In the
            presence of duplicate key values, all records associated with the
            designated key will be discarded. If key is 
            MultipleDatabaseEntry, delete multiple data items using keys from
            the buffer to which the key parameter refers. If 
            key is MultipleKeyDatabaseEntry, delete multiple
            data items using keys and data from the buffer to which the key 
            parameter refers.
