Project Summary
A person having an average household income is often sensitive to price differences in case of
items purchased regularly. Grocery expense is one such unavoidable expense which forms a major
proportion of household expenditure and hence, every individual would want to save on it without
sacrificing the required items. Grocery shopping often becomes a tedious task when one is ignorant
about the prices which differ from store to store for a similar item. With n number of stores around
your locality, it is hard to find which will be one best store to purchase your groceries at the
cheapest price possible.
A person on average buys groceries 4-5 times a month. He is either forced to travel store to store
looking out for the cheapest price of a product which is a waste of time, energy and money or end
up spending more on a totality basis. If a person wants to buy a list of products, they will choose
a store assuming they will get their desired product at the cheapest price. This may be true in some
cases, but the price of products keeps varying from time to time which will not always be the best
option monetarily.
The proposed database will assist consumers in selecting the most suitable store considering
various factors like the price of products to be purchased and quantity to be purchased. The
database will integrate the data of various stores on a single platform. It will include products
available, price, and monetary benefits available to customers. Based on the items required by
the consumer, the system will compute the total cost of all such items and suggest the best store
which should be visited.
The system would also allow the store managers to track the inventory level, identify the
depleting items for which purchase order needs to be raised on time to ensure availability of
stock, update the product prices and increase sales by attracting more consumers through
promotional offers and competitive prices.
