Oracle Database recognizes objects that are associated with a particular schema and objects that are not associated with any particular schema, as described in the sections that follow.
A schema is a collection of logical structures of data, or schema objects. A schema is owned by a database user and has the same name as that user. Each user owns a single schema. Schema objects can be created and manipulated with SQL and include the following types of objects:
Other types of objects are also stored in the database and can be created and manipulated with SQL but are not contained in a schema:
In this reference, each type of object is described in Chapter 10 through Chapter 19, in the section devoted to the statement that creates the database object. These statements begin with the keyword
CREATE. For example, for the definition of a cluster, see CREATE CLUSTER.
