1. Introduction

The aim of this project was to examine all the data in relation to

Charity School Events and then prepare it, in order to build a

database using Oracle SQL. The table names and column names

were supplied and therefore the initial step was to find the

relationships between each table nd then populate the tables,

these relationships were modelled on an Entity Relationship

Diagram (Erd) and outline the Primary Key and Foreign Key in

each table.

I will cover every aspect of the SQL Command Set: Data

Manipulation Language, Data Description Language, Data

Controlling Language And Select Statement.
