As an XML expert you are required to model a system for an online bookshop. After an interview with the shop manager you have the following information:

• The detail of the bookshop includes shop name, address, telephone number, website address (URL), and logo (image).
• The bookshop has the following types of items for sale: books, magazines, music CD/DVD, games, etc. Each item has its name, item number, description, quantity and price.
• A book can be paperback or hardback book.  A book also has information about title, publisher, author, ISBN number, publish year, edition, optionally with CD, etc.
• A magazine can be a normal or e-magazine with name, publisher, ISSN number, publish year and Issues.
• The music CD/DVD have title, publisher, publish year, the media (CD or DVD), and signer/player etc.
• A game has name, producer, year of release and PEGI rating.  It also has the information of platform (e.g., PC, Wii, Xbox) and the media (CD, online, DVD). 

Task 1. Analyse the above-motioned scenario. Prepare data in XML, and add additional information you wish to record. Draw your data structure. You should include:

• 3 pieces of data or more for each item.
• 2 or more attributes
• At least one optional data field.                                                       

Task 2. Using the above information and your additional information, and the data structure from Task 1, create an XML document and name it catalog_{studentID}.xml. (e.g, catalog _03047791.xml)                                         

Task 3. Using the structure of catalog _{studentID}.xml as a model, create a DTD file named catalog _{studentID}.dtd. Apply catalog _{studentID}.dtd to the contents of catalog _{studentID}.xml. Validate the XML document against your DTD using an online validator or AltovaXML2008.

Task 4. Create a CSS file catalog _{studentID}.css to render your XML data file to a web browser.

• Create a list
• Create at least one border
• Use at least two different font sizes and two different font families.
• Use two different font colours, at least one of which is defined using RGB values.
• Display logo a image.
• Use at least one floating box

Task 5. Write a short report up to 1000 words (save as report1 _{studentID}.doc, a word document) to describe how you designed and implemented the coursework part 1. The report should include the data structure. Discuss the limitations of DTD and CSS.
