Iv. synonyms(a) What are synonymsA synonym is essentially an alias for a specified schema object. Synonyms provide a degree of security by masking the names and owners of objects and providing location transparency for remote objects in a distributed database.

CREATE VIEW statement, Oracle creates the view even if there is a series of cases.The query for a view definition references a table that does not exist.The query for the view definition references columns that are not valid in an existing table.The owner of the view does not have the required permissions.In these cases, Oracle only checks for syntax errors in the CREATE VIEW statement. If the syntax is correct, the view is created and the definition of the view exists in the data dictionary. H
