DATABASE MANAGEMENT SYSTEM
Background
Requirements
The business rules required for the implementation of the
database are described below:
 The details of the patrons are to be stored in the system with
the customer number being unique attribute which is to be used
for the reference of the customer data.
 The details of the departments are to be stored in the
database.
 The names of the stores and their addresses and fax are to be
stored in the system identified uniquely by their store
number.
 The details of the products and their prices are to be stored
in the system.
 The details of the orders made by the customers in the system
and employees handling the orders are required to be stored in
the system.
Mission statement
The system would be helpful for the organization in
maintaining their data also provide the organization with efficient
data storing options that would be increasing the business
efficiencies of the organization.
DBMS Selection
The Organization has chosen phpmyadmin mysql available on the
xampp server to develop their database that would be supporting
their backend process for the development of the system.

Group report
From the personal point of view, it can be said that the AMC
organization is in an urgent need to resolve the issues that they
are facing with the current business procedures. The organization
has various branches across of Australia and it becomes very
difficult for the organization to maintain their business process.

DATABASE MANAGEMENT SYSTEM
Therefore, the development of the database would be very useful for
the organization in improving their business strategy.
Challenges and solution
The major challenges faced was during the development of the
data and working in the command prompt interface. The main solution
obtained to this problem is that the ER diagram was developed after
reading the case study thorough. The Development of the ER diagram
was then done with the help of the MS Visio Tool. In addition to
this, the normalization of the tables to be included in the database
were performed. Hence, a clear view of the database that was to be
developed was obtained. Hence, the solution was obtained.
In addition to this, the YouTube videos were referred for
working on the MySql command prompt interface. The videos helped a
great deal in developing the queries on the command prompt
interface. Hence, the problem was solved.
