Creating a database for Buy a Motor.

Extracts from this document...

Introduction

Buy a Motor Statement of Problem Buy-a-motor is a car trading company. It puts the sellers of second hand cars in touch with those who want to buy them. They normally keep records in filling cabinets and contact people through telephone and letter, and buyers call them for info on the cars, which are available to meet there requirements. However this method has become out dated and they need to improve. I will need to create a database that can display all of their data, as efficent but hopefully better than the excising system. Investigation and Analysis If Buy-a-motor change their system to a database the information will be quicker to access and it would be more efficient as they would not have to use paper to print everything. There could also email their files to people to speed up the service. To research what type of data and information are included in adverts for cars I went to these different areas * Auto Trader * My Dad * The Internet I found that they all agreed that you want to know: - 1. The Age 2. The Make/ Model 3. If it's had an MOT 4. It's Service History 5. ...read more.

Software Resources Buy-a-motor will also need to purchase some software, these will include, but not be limited to * Microsoft Access, for the database to be on * Microsoft word, for writing out letters to clients The software needs to be able to * To save information so that it can be retrieved for later use. * To be able to print off data, so that it can be sent to potential clients. * Alter Data so that new cars can be added * Inform someone when they have made a mistake (validation rule, etc) * To be able to get sent via email to clients. Microsoft Access can do all of the tasks, very efficiently. It is also available on the school network. To run these programs you would need a Windows operating system, preferably windows 98,2000/ME or XP. Data Input Form (See next sheet) Data Structures Field name Why it is needed Example of typical data Data type Max field length Could it be coded? Could it be validated? Surname To identify the owner Smith Text 25 No No Area To know where the car is North East Text 15 (3 if coded) ...read more.

Conclusion

At first my database would not store details of cars correctly because the input boxes were incorrect (text is number etc). I corrected this and it can store details now. I entered 27 Details in to the data base, this could be transferred by email or 3 1/2 inch floppy disk, so they could store 1000's of cars on their database. * It must be able to be altered and updated with ease (e.g. add or delete stock etc) I can test this by entering test data when it is completed. This is very important that the database can do this. I can enter new data and it is easily done if people know a little bit about MS Access * Allow for a search of the data base for specific cars e.g. A make or Price Range, this can be tested by, again entering in test data. My project managed to do this but it is not very user friendly, people would struggle with the queries. If I were to do my project again or improve on it I would add an easy input screen, so that people who don't have knowledge of access can use the database. The data capture form is very easy to fill in and is not to demanding, for less intellectual people Gareth Jones 10L ...read more.
