In Oracle, tables are stored in segments, which are stored in extents, which are stored in tablespaces, which are stored in datafiles on the host system. This is a DBA issue. No application developer should concern themselves with this topic, except to identify data and query needs to the DBA.

If one is wanting to create a table in Oracle one must use the "Create Table" statement. These tables are partially defined by the columns contained and the information in the column. One must first decide the proper column type and then these data types are used in the Create Table statement. One must be somewhat familiar with Oracle in order to create these tables and additional information can be found on the DBA-Oracle website.

Oracle is a database. Oracle is a Relational Database Management System which is a specialized implementation of a database. It is designed to hold data that is related to one another and organized in the form of schemas and tables.
Tables
Information about databases and systems is typically stored in system tables called data dictionaries or system catalogs. These tables contain metadata about the structure and organization of the database, as well as information about users, privileges, and other system-related details. Database management systems like Oracle, MySQL, and SQL Server provide built-in tables for querying this information.
