Coursework Assignment 2023/24
The coursework assignment is an individual assessment weighted 100% of the marks for the module. It is designed mainly to assess the practical aspects of the module. It requires the student to analyse and modelling a database based on a given case study. You are asked to provide a appropriate database design documentation detailing the modelling process.
Case study – Goldsmith Antique Associates
Goldsmith Antique Associates is an established antique dealer’s business located in east London. They have a shop on the high street but most of their business comes from locating items for customers and dispatching these by mail anywhere in the world. Their reputation depends on their knowledge of their customers’ special interests, and being able to locate items that will satisfy their requirements.
Your job is to build web-based database system that will help in keeping track of customers’ orders, their special interests and the items that might satisfy those special interests. Now, the firm has a set of manual files for customer records, item records and sales.
You have been given various items from the files to examine.
1. Customer Record Sheets
The customer record sheet looks as though it started off quite orderly as a set of type written documents but has then had handwritten additions added. King Smith the office manager tells you:
‘The trouble is that we get extra information with nowhere to put it, so I tend to scribble things on the sheets. The notes section is usually about the customers’ special interests but sometimes I have to add another address there. A lot of our clients are very rich and have many addresses. They usually have an address where they would prefer their goods sent but this may be different from where they live or where they want the bill sent. It would be good if we could have something on the new system that we would sort this out. Maybe something that showed different address types or where they wanted things sent.’
Customer Name: Severain Riccardi
Address: 7 Halsall Road, Barnes, London . find out this custmomer’s postcode Mark S.
Tel: 020 980 88888 Notes:
Severain is interested in French painting from the Impressionists onwards.
He has another address 89 Rue de Balzac, Paris, France. This is where he usually is. Don’t know the telephone for this. Important, all items should be sent to the London address.
Customer Name: Amanda O’Brian
Address: 89 Andover Park, West Drayton Tel: 090 998 7654 Notes:
Amanda is interested in items from Japan and China.
Customer Name: Paul Goodman
Address: c/o PO Box 89 London E1 Tel 9383 8938383 Notes:
Above is billing address. Don’t send goods there.
Mr. Goodman is interested in all types of militaria.
2. Item Records
Item records are a set of card index files. As shown below. King Smith had the following to say:
‘The biggest headache we have is with keeping track of items. The major headache with items is that we file them by category. So, we have categories like ‘Militaria’, ‘Art’ and ‘Equestrian’ amongst many more. The trouble is that some items fall into more than one category. For example, the Duke of Wellington’s sword would be ‘Militaria’. A painting of the Duke of
Wellington would be ‘Militaria’ and ‘Art’ whereas a painting of the Duke on his horse would be ‘Militaria’, ‘Art’ and ‘Equestrian’. What we do now is we copy out the cards and put them into each category. This involves a lot of duplication. If you could design a system that got round us having to do this then you would earn my sincere gratitude’.
‘‘Provenance’ refers to the files of documentary evidence proving the history of the item. These are kept in a safe. The new system will just need to hold a file number referring to these’.

3. Sales Records
To keep track of sales (Sales Order and Sales Order Lines), records are kept. King Smith comments:
‘When we have information about items that we think might be of interest to a client, we inform them, and they will order from us either by sending in one of the order forms that we had sent out to them earlier or over the phone, in which case we fill in the order. The order is usually for several items as you can see from our order form below.’
