Tables
•
Using tables is the best way to store structured data.
•
They consist of rows and columns.
•
Columns possess
headers
defining the data type stored in them and
the name with which the column can be addressed.
•
Rows
hold the actual attribute which are stored in the database.
•
Each row is uniquely identified by a
Primary Key
that is represented
by one or more columns.
•
A
Foreign Key
points to a column or a set of column in another
(referenced) table.
