Sybase IQ distributes user data across multiple disks at the application level by representing each device as a dbspace. A dbspace can be an operating system file or a raw disk partition. Dbspaces can contain both user data and internal database structures used for startup, recovery, backup, and transaction management.
PowerDesigner models dbspaces as tablespaces (see Tablespaces and Storages (PDM)with the following additional properties on the General tab:

Read-only |
