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.
