Answer / ramana
The relationship between a database server and an
application server is a one-to-many model.
That is, a single database server can have multiple
application servers connecting to it.
The database server simultaneously handles the application
server connections, Development Environment connections,
and batch programs running against it.

Answer / dips
In a one-to-many relationship, each row in the related to
table can be related to many rows in the relating table.
This allows frequently used information to be saved only
once in a table and referenced many times in all other
tables. In a one-to-many relationship between Table A and
Table B, each row in Table A is linked to 0, 1 or many rows
in Table B. The number of rows in Table A is almost always
less than the number of rows in Table B.
example:
authors table
============
author_id (primary key)
lastname
firstname
book_id (foreign key - link to book_id of books table)
books table
===========
book_id (primary key)
title
author_id lastname firstname -> book_id title
