A database is divided into logical storage units called tablespaces, which can be used to group related logical structures together. Each database is logically divided into one or more tablespaces. One or more data files are explicitly created for each tablespace to physically store the data of all logical structures in a tablespace.
Note: You can also create the bigfile tablespaces, which are tablespaces with a single but very large (up to 4 billion data blocks) data file. The traditional smallfile tablespaces (which are the default) can contain multiple data files, but the files cannot be as large. For more information about the bigfile tablespaces, see the Database Administrator’s Guide.
