Aims and Objectives

Classics Online is a Web-based book and music retailer specialising in pre-1980s hardback literature and vinyl records.  The company requires a Web Service based application developed in Visual Studio C# 2010 to manage users, orders, transactions and to log all orders placed.

The company carry the following limited stock:

Books

Records

Gift options

Postage

Note that "gift wrap" and "gift box" are mutually exclusive and cannot both be applied to the same order.  If either is selected then that selection will be applied to the entire order.  A personalised message may be added with either selection, or with neither.  Gift option prices are calculated before postage and are included in the total value of the order for postage calculations.

Multiple copies of the same book or record may be purchased in a single order.

Design and implement two Web Services; one to register and manage user accounts, including personal and payment details for customers, and a second to create and manage orders/transactions for these customers.

Create a Windows Form or ASP.NET application to act as a client for the Web Services, clearly displaying the type and number of products ordered (the type and number of controls are a part of the design process).  The form should include a section which displays the separate cost for books, records, gift options and postage.  Finally display an overall cost for a transaction/order.

Procedure

v  Design a Web Service to register the personal and payment card details of new customers.

o   Add a login method for returning customers.

o   Create a client form to access and utilise this functionality.

v  Design a second Web Service to store all transaction details to a database table.

o   Add method(s) to calculate the item and gift costs involved for each order/transaction.

o   Add a method to calculate the cost of postage for the transaction.

o   Implement in the client the relevant functionality to access and order the range of stock and services available from the retailer, utilising the personal details registered by the first service.

v  Incorporate an additional, original feature of your choosing which augments the service, the client or both.

v  Write a report that critically analyses the design of the software components with respect to the major concepts, principles and good practice.

o   Describe how the software could be deployed as part of a commercial distributed system.
