Grocery Stop: Database Management Tool

SECTION II: PROJECT SUMMARY
Background:
There are more than 20,000 students in Syracuse University. Each student have their individual
food requirements. Every student has to go to a nearby grocery store and buy the products they
desire. Usually grocery shopping is done house wise where the students travel to nearby
supermarkets like Walmart, India Bazaar or Price Rite by ordering a cab and purchase groceries
every week.
The process is cumbersome and not everyone has the time to go to these marts every week. While
all the houses go for grocery shopping there is no method to coordinate or know who all are going
to a supermarket and on which day. If this information is available on some platform, students can
better coordinate and save their travelling expense or share a ride to the same place.

Currently there is no platform where people can view information regarding grocery shopping,
share a cab to nearest supermarket or coordinate their time of visiting these markets. So there is a
need for an efficient solution to solve this issue and better organize the entire process.
The developed solution is GROCERY STOP. A database management tool which provides the
following functionalities:
 Students can register and add their shopping trips in Grocery Stop. Only the registered
users can add and view grocery information while the non-registered users can only view
information.
 The grocery information includes user name, name of store, date and time of visit along
with the mode of travel, available space, fare and start and end point for travelers.
 Students can easily collaborate with other users by viewing Grocery Stop. Students can
share cabs to the same store or can ask their friends to purchase products for them.
 The administrator is allowed to delete grocery entries along with users. Only the
administrator can add a new store.
 Grocery Stop will have three separate views for registered users, non-registered users and
administrator.

PAGE 6
BUSINESS RULES:
 Administrator can add or delete data entries in grocery information.
 Administrator can add and update stores. Only admin can add a new store
 Non Registered users can also view grocery and travel information. Their entity is not
added since the database management tool doesn’t store any related information.
 Data Entries will be deleted once the DateOfVisit in Grocery Information table is passed
by the administrator
 Non registered can register to gain access database
 Customer can add and view travel information. Travel fare needs to be included.
 User can add any number of grocery and travel entries.
 All the travel entries must relate to one grocery entry. It’s not mandatory to mention
travel information in every grocery information for the customers
SECTION IV: DATABASE INFRASTUCTURE
The database system infrastructure used is based on a client-server model. SQL Server is used as
the database engine and Access is used as the interface design tool. Data is inserted, deleted,
updated, and queried from the SQL Server database with the help of forms on Access. Useful data
stored on the SQL Server database can also be viewed with the help of reports generated through
Access. Based on a login checked on Access users are allowed to access the database in SQL.

SECTION VI: SQL STATEMENTS FOR ANSWERING MAJOR DATA
QUESTIONS
1. SEARCH FOR TRAVEL OPTIONS TO A PARTICULAR STORE:
The user can search for particular stores and retrieve all the users going to the same store. The
query joins Travel Information table with Store and Grocery Information
SELECT dbo_GSstore.storeName, dbo_TravelInfo.userName, dbo_GSInformation.dateOfVisit,
dbo_GSInformation.timeOfVisit, dbo_GSInformation.userName, dbo_TravelInfo.travelMode,
dbo_TravelInfo.travelStartPoint, dbo_TravelInfo.travelEndPoint, dbo_TravelInfo.travelFare,
dbo_TravelInfo.availableSpace

FROM dbo_TravelInfo INNER JOIN (dbo_GSstore INNER JOIN dbo_GSInformation ON
dbo_GSstore.[storeID] = dbo_GSInformation.[storeID]) ON dbo_TravelInfo.[travelInfoID] =
dbo_GSInformation.[travelInfoID]
WHERE (((dbo_GSstore.storeName)=[Store name?]));
This form displays the grocery information page for the user. The search stores for available travel
button triggers this query
This is a parameterized query. It takes in value from this parameter and enter it in the database to
generate reports
Based on the parameter entered, the query displays report which is grouped by the store name
entered. This report displays the available travel option to Walmart store.

Tapan Desai
PAGE 17
2. SEARCH FOR A PARTICULAR USER:
The users can search for a particular user to retrieve their contact information. Using this query
the user can query the database for information. The query joins user table to customer table
SELECT dbo_GSuser.userName, dbo_GSuser.userContactNumber, dbo_GSuser.userEmail,
dbo_GSCustomer.areaOfResidence
FROM dbo_GSuser INNER JOIN dbo_GSCustomer ON dbo_GSuser.[userName] =
dbo_GSCustomer.[userName]
WHERE (((dbo_GSuser.userName)=[Name of the user?]));

Tapan Desai
PAGE 18
This is a paramterized query where user can enter the name of the user to gain customer
information.
Based on the query a report is generated joining two tables GSUser and GSCustomer.
3. SEARCH USERS BASED ON THEIR AREA OF RESIDENCE:
The users can search for other users based on their area of residence. The query joins customer
table with travel information, grocery information.
SELECT dbo_GSCustomer.userName AS dbo_GSCustomer_userName,
dbo_GSCustomer.areaOfResidence, dbo_GSInformation.userName AS
dbo_GSInformation_userName, dbo_GSInformation.dateOfVisit,
dbo_GSInformation.timeOfVisit, dbo_GSInformation.GSUserComments,
dbo_TravelInfo.travelMode, dbo_TravelInfo.travelStartPoint, dbo_TravelInfo.travelEndPoint,
dbo_TravelInfo.travelFare, dbo_TravelInfo.availableSpace, dbo_TravelInfo.storeNameTravel
FROM dbo_GSCustomer INNER JOIN (dbo_TravelInfo INNER JOIN dbo_GSInformation ON
dbo_TravelInfo.[travelInfoID] = dbo_GSInformation.[travelInfoID]) ON
dbo_GSCustomer.[userName] = dbo_GSInformation.[userName]
WHERE (((dbo_GSCustomer.areaOfResidence)=[Area of Residence?]));

Tapan Desai
PAGE 19
A parameterized query which shows the users residing in a particular area.
Based on the entered query, information regarding the store name and travel method is displayed
in this report.

4. QUERY BASED ON DATE FOR ADMINS TO GROUP GROCERY INFORMATION:
The admin can query using this query to retrieve information of all the users visiting a particular
store on a particular date. The admin can easily search the date and delete the information based
on this query
SELECT dbo_GSInformation.[GSInformationID], dbo_GSInformation.[storeID],
dbo_GSInformation.[travelInfoID], dbo_GSInformation.[userName],
dbo_GSInformation.[dateOfVisit], dbo_GSInformation.[timeOfVisit],
dbo_GSInformation.[GSUserComments]
FROM dbo_GSInformation
WHERE (((dbo_GSInformation.[dateOfVisit])=[Date of Visit?]));

Tapan Desai

This query is used by the administrator to search dates and grocery information based on those
dates. This query assists the administrator to easily delete information which has passed a
particular date. The form generated based on that query has a delete button to ease the delete
procedure.
