During the book, we use a tool developed by an author (The full source code is made available to readers, with an appendix devoted to its full description), which uses the structure of a relational database to build a rich object layer. This abstracts a lot of the complexity of building a rich application object model and makes it possible for application architects and programmers to create a powerful, highly reusable object model with a simple desktop application.
The book begins by taking a look at the overall design of the enterprise application and then moves on to show how the enterprise can be accessed from desktop and mobile applications, as well as over the web using ASP.NET. Web Services also play a big part by exposing the functionality of the underlying business objects, as well as being used for authentication amongst other things. Of course, security is discussed where particular issues arise, as well as being covered in more depth in its own chapter. Once we have the enterprise application up and running, we look at administration, hosting, and management.
