CREATE TABLE, DROP TABLE Statements
Before explaining how to create table I would like to give you
slight explanation about the word “Schema”, what it is? And
what it means in Oracle Jargon. Schema is basically a Latin word
and it means a diagrammatic representation; an outline or model.
Schema can be visualized by looking at the organization chart of
a company e.g., the one shown below.
