CASE STUDY-1

$100 million chain of general stores is struggling to implement information system. Due to lack of proper information system, the store management is unable to maintain the daily records of customers, products sold, and there is a total confusion on reports like demand and supply of products in various retail outlets,

etc leading to a poor supply chain management. The basic requirement of the information system is to manage data for customers, products, demand and supply records in particular retail outlets, quantity supplied and available, payments made by customers, etc. That is to develop a small supply chain management system.

A Question

Suggest the database design for above system with ER model using UML notations.

CASE STUDY-2

big manufacturing industry in consumer goods located in different countries is facing huge loses due to mismanaged data. Existing system is not capable enough to tackle the integration of various key departments like: stores, shop floor, plant maintenance, manufacturing, quality, sales and distribution, etc.

One department is not in a position to know the status of process and items available in other. E.g. sales department while bidding for the orders, can not calculate the existing capacity, product balance in warehouse, etc. Management want to integrate at least purchase, manufacturing and sales department of the organization to start with.

A Questions

1. Purpose process flow of purchase, manufacturing and sales departments.



2. Give ER diagram for the above process flow.
