Example:
For each data devspace, the number of logical and physical read and write accesses is displayed:
Catalog
denotes the data devspace used by the data dictionary of the database system. Frequent writing to this area is a sign of modifications made to the database design.
Permanent
is the actual data devspace for permanent data.
Temporary

Leaf, Level 1, Level 2, Level 3
