In this book we've gone from nowhere to creating a DNA-based application that uses transactions and message queuing. The application provides a compact, robust, easily extensible and re-usable core of business functions and rules, implemented as components in a range of formats and languages.
We've built components using Active Server Pages, Visual Basic, and HTML Scriptlets; and client-side interfaces with HTML and Dynamic HTML, VBScript, JavaScript, and Visual Basic. We've handled data using SQL Server stored procedures, using custom VB components through ADO, and using client-side data-binding with RDS. We even explored the technique of sending recordsets to the client through the data factory interface, and packaged them up using a custom VB routine we called a
.StringBag
So what's left to do now? Well, in this chapter we're going to take that final step and put our application's core components to work as part of a publicly-accessible Web application. We'll look at the issues involved in this, take a view on how we plan the final product, and see how we've implemented it in our example.
In this final chapter you'll see:
We'll start with a look at what applications like this are really designed to achieve.
