What Is a Database Table?
A database table is a basic unit of data logical storage in an Oracle database. Data is stored in rows
and columns. You define a table with a table name, such as employees, and a set of
columns. You give each column a column name, such as employee_id, last_name,
and job_id; a datatype, such as VARCHAR2, DATE, or NUMBER; and a width. The
width can be predetermined by the datatype, as in DATE. If columns are of the NUMBER
datatype, define precision and scale instead of width. A row is a collection of column
information corresponding to a single record.
