INTRODUCTION

This lab work was meant to introduce students on how to create a database, tables, inserting data into the tables and finally to query specific data from the tables.

There is a tool called SQL Developer that was used in this work to create a connection that can be used to link tables using their primary keys as foreign keys in other tables so as to have access to those tables. This same tool was also used to create tables and enter data into those created tables.

CREATING THE DATABASE, THE TABLES AND INSERTING DATA INTO THE TABLES CREATED.

TASK 1: CREATING A DATABASE

In this task we are asked to create a database to be named in the format StudentNo_Music. Once we are done creating the database we need to create tables as shown in the lab question. Furthermore we are asked to populate the tables with information as provided for in the question. The figures below illustrate the creation of the fore mentioned tables of the database 201302606_Music.
