The data file is the physical storage unit of the database, while the tablespace is the logical component of the database. The database data is stored in the tablespace, and a tablespace can be composed of one or more data files. A data file can only belong to one tablespace. Once a data file is added to a

segment can belong to only one tablespace and can span multiple data files.C. A segment consists of one or more zones. 3) ZoneA. As the segment grows, additional segments will be allocatedB. DBA can manually add a partition for the segmentC. A zone is a continuous set of oracle blocks.D. A zone can only exist in one data file 4) BlocksA. The block is the smalles

Basic Relationship: Database---Table space---data segment---partition---data blocktable Space (tablespace)A tablespace (tablespace) is a logical entity that contains a physical data file that holds all the data available to the database, so the size of the tablespace is also the sum of the size of the data file that co
