Abstract
An application has been developed that enables customers to browse a catalog of books by category or range, add selections to a virtual shopping cart, remove items from the cart and simulate processing an order by logging in and submitting updates to the order table in the database. The power of Extensible Markup Language (XML) has been leveraged and its ability to represent data and structure, Web Services and their methods explored, databases designed and procedures stored, custom code behind classes in C# developed and a multitude of uses covered for ADO.NET. The chapter also explores database design and implementation, creating two databases for the application, one for Access and one for SQL. The chapter covers entities and their attributes and how both work with each other to create a normalized database. Lastly, a set of stored procedures has been developed that handles all data interaction with the database, preventing the use of “ad hoc” queries against the database.
