Database Report

Introduction

A database contains a collection of information organised in such a way that a computer program can quickly select pieces of data. You can think of a database as an electronic filing system.

A field is a single piece of information; a record is one complete set of fields; and a file is a collection of records. For example, a telephone book is analogous to a file. It contains a list of records, each of which

To access information from a database, you need a database management system. This is a collection of programs that enables you to enter, organize, and select data in a database.

I am creating a database to hold the information of a Video/DVD shop e.g. customer id, customer name, customers surname, address etc.

People use database because it’s a new and advanced way to keep information unlike having information on paper. Using database is quicker to access information where as having information stored on paper it would take time to access it. It is a suitable place where information can’t be lost, can be easily retrieved, and easy to edit information.

The database I have created is about a video/DVD renting shop (Video &DVD EXPRESS), that is renting videos and DVDs to people and I have to create a database to show how many people have created a account, how many videos and DVDs they have, and customer details.

There are two user needs, one of the user needs will be that the user will have to edit information when a new customer joins or a customer leaves. And the second user need can be that the user will have upload more information about films and their details e.g. prices, genre, classification etc.

 

When this database is finished it will enable me to find customer, video & DVD, rental information very quickly. Also to see what people are entitled to what kind of films, and what people have returned and not returned videos & DVD etc.

Planning

I need to get data, which contain the customer’s names, DVD titles, Video titles and some loans information. I will have to make this information up, as I don’t know where to get these details.

The following are the field tables and the data types that I am going to use and I will be explaining why I am going to use them:

Video table

Field Names:                                Data Type:

Video Number                                Auto number        

Video Title                                        Text

Classification                                Text

Genre                                                Text

Price                                                Currency

DVD Table

Field Name:                                Data Type:

DVD Number                        Auto Number

DVD Title                                Text

Classification                        Text

Genre                                        Text

Price                                        Currency

I am using all these field names and data types because there are appropriate to use for this database.

The video is used to represent a video in numbers so that when ever a person checks for that video/DVD it would be easy to check if its available or has been rented by another person.

The video title is used for identifying what video is which

The classification is used to see what films are entitled for kind of ages, all video/DVD shops will need use this, if not this could turn into a illegal action.

Genre is used to identify what kind of film it is for a example the film “Dodge ball” comes under comedy.

The price shows the customer how much for renting that certain video or DVD
