a named area of disk storage
a storage allocation that can store up to a fixed number of data rows
a storage element that consists of one or more chunks
An additional database file that creates more space for data. A database can be held in up to 13 separate files (an initial file and 12 dbspaces). Each table, together with its indexes, must be contained in a single database file. The SQL command CREATE DBSPACE adds a new file to the database. See also: database file.
A logical collection of one or more chunks of contiguous disk space. Because chunks represent specific regions of disk space, the creators of databases and tables can control where their data is physically located by placing databases or tables in specific dbspaces.
