Purpose of the assessment (with ULO Mapping) The purpose of this assignment is to develop skills in managing data in databases and to gain understanding of data model development and implementation using a commercially available database management system development tool.

On completion of this assignment students will be able to:

a. Model organisational information requirements using conceptual data modelling techniques.
b. Convert the conceptual data models into relational data modeland verify their structural characteristics with normalisation techniques.

1. The snapshot of Party_BookingDB database structure is given below. Party_BookingDBis a database that keeps track of information about the Bookings, Staff, Menus and Customers registered in the system

You are working as an IT specialist in this organisation and are required to extract information from this database by executing SQL queries according to the instructions given below.

The primary keys are marked in the following snapshot of Party_BookingDBdatabase attached figure 1.
Figure 1: Snapshot of Party_BookingDBdatabase Database Answers Ltd. 2016

a. First you need to implementthe above database in MS Access. You only have to create 5 tables for Bookings, Menus, Menus_Booked, Menu_meals and Staff. You do not have to create other tables in the Figure1. And populate those tables with suitable data (at least 3 records per table).

You can use Datasheet view in MS Access or SQL statement (as given below) to enter suitable data records.
INSERT into TableName
VALUES ("..","..",.....)
NB: You only have to create 5tables.
And you need to upload your database on submission link along with the word document.

This is an individual assignment; it should be your own individual work (You should not copy Ms Access Database). If not, this is considered cheating and you will get zero marks for the whole assignment.

Write SQL queries for the following questions.

Execute the queries on the "Party_BookingDB" database you created in MS Access.Include screen shots of the outputs and all SQL statements you used to answer following questions

b. Prepare a list of BookingID, StaffID, CustomerID anddate_of_eventof all Bookings. You are required to sort the list in descending order of CustomerID

c. Assume that you want to count how many bookings are there on the date "24th August 2018". Write a query to find the number.

d. Display BookingID, CustomerID,StaffID,first_name(staff), date_booked of all eventsscheduled for24th August 2018.
(Hint: Join Bookings and staff)

2. Figure 2(attached) shows the ER diagram that captures important information in the tracking of Suppliers and items in a retail store. This retail store purchases items from a number of suppliers. It keeps track of the items purchased from each supplier, and it also keeps a record of suppliers' addresses. Items are identified by ITEM-TYPE and have a DESCRIPTION. There may be more than one such address for each supplier, and the price charged by each supplier for each item is stored. Suppliers are identified by SUPPLIER-ID.

a. Convert the ER diagram into a relational database schema. Be certain to indicate primary keys (underline).
EgSupplier (SupID: NUMBER; SuppName:text,.....)

b. Identify Associative /Bridge entityin the ER diagram of figure 2. Explain purpose of using Associative /Bridge entity.

c. Do we need a separate entity for supplier address? Can we include it as an attribute in the Supplier entity? Explain your answer.

3. Business intelligence (BI) is a term that describes a comprehensive, cohesive, andIntegrated set of tools and processes used to capture, collect, integrate, store, and analyse data with the purpose of generating and presenting information to support business decision making.Components of the BI framework are given in the Figure 3.

Data visualization is one of the BASIC BI ARCHITECTURAL COMPONENT.

Answer following questions.

a. Why is data visualisation important in Business Intelligence?

b. Tableau is a data visualization tool.Tableau can help anyone see and understand their data. Connect to almost any database, drag and drop to create visualizations.

Install Tableau Public on your laptop /computer and create any 2 visualisations. Follow the following instructions:

i. First go to Tableau Public and enter your email address and select "Download the App"

ii. Then you can download the software and run the .exe file to install.

iii. Now you will get the following starting screen. Here you can upload MS excel or MS Access file. Watch this video

iv. You can use any MS excel, MS Access file or any data file to create 2 visualisations. It should be your own individual work.
