A tablespace is a storage location where the actual data underlying database objects can be kept. It provides a layer of abstraction between physical and logical data, [1] and serves to allocate storage for all DBMS managed segments. (A database segment is a database object which occupies physical space such as table data and indexes.) Once ...
OID uses standard Oracle database structures to store its internal tables. In Oracle version 9 databases, by default, many Oracle LDAP Table Stores use tablespaces with names beginning with the OLTS_ (and occasionally P1TS_) prefixes. Relevant default schemas used may include ODS (for "Oracle directory server") and ODSCOMMON.
Oracle Database 23ai: 23.4.0 On May 2, 2024, Oracle Database 23ai [10] was released on Oracle Cloud Infrastructure (OCI) as cloud services, including OCI Exadata Database Service, OCI Exadata Database Cloud@Customer, and OCI Base Database Service.

A database object is a structure for storing, managing and presenting application- or user-specific data in a database. Depending on the database management system (DBMS), many different types of database objects can exist. [1] [2] The following is a list of the most common types of database objects found in most relational databases (RDBMS):
However, Oracle databases store schema objects logically within a tablespace of the database. The data of each object is physically contained in one or more of the tablespace's datafiles . For some objects (such as tables, indexes, and clusters) a database administrator can specify how much disk space the Oracle RDBMS allocates for the object ...
Oracle Database provides information about all of the tables, views, columns, and procedures in a database. This information about information is known as metadata. [1] It is stored in two locations: data dictionary tables (accessed via built-in views) and a metadata registry.
The Oracle database tablespace CWMLITE stores OLAPSYS schema objects and integrates Oracle Database OLAP Option with the Oracle Warehouse Builder (OWB). [2] The CWMLITE name reflects the use of CWM — the Common Warehouse Metamodel, which Oracle Corporation refers to as "Common Warehouse Metadata".
Oracle has its own spin where creating a user is synonymous with creating a schema. Thus a database administrator can create a user called PROJECT and then create a table PROJECT.TABLE. Users can exist without schema objects, but an object is always associated with an owner (though that owner may not have privileges to connect to the database).
