Assignment Description

Part A: (30 marks)

The quiz will open after week 5. Paste below the summary of your Assignment 1 quiz results from Moodle.

Part B: (70 marks)

The snapshot of Party_BookingDB database structure is given below. Party_BookingDB  is 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_BookingDB database shown in figure 1.

Figure 1: Snapshot of Party_BookingDB database  © Database Answers Ltd. 2016

  1. First you need to implement the above database in MS Access. You only have to create 5 tables for Bookings, Menus, Menus_Booked, Menu_meals and 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 5 tables.

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.

(10 Marks)

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

(3 marks for each screen shot & remaining marks for the SQL query)                  

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

 (10 Marks)

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

Figure 2 shows the ER diagram that captures important infomation 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.
