Database server administrators sometimes must track disk use by a particular table. A tblspace contains all the disk space allocated to a given table or table fragment (if the table is fragmented). A separate tblspace contains the disk space allocated for the associated index.

A tblspace, for example, does not correspond to any particular part of a chunk or even to any particular chunk. The indexes and data that make up a tblspace might be scattered throughout your chunks. The tblspace, however, represents a convenient accounting entity for space across chunks devoted to a particular table. (See Tables.)
