As web developers, our lives revolve around working with data. We create databases to store the data, code to<br>retrieve and modify it, and web pages to collect and summarize it. This is the first tutorial in a lengthy series<br>that will explore techniques for implementing these common patterns in ASP.NET 2.0. We'll start with creating<br>a software architecture composed of a Data Access Layer (DAL) using Typed DataSets, a Business Logic Layer<br>(BLL) that enforces custom business rules, and a presentation layer composed of ASP.NET pages that share a<br>common page layout. Once this backend groundwork has been laid, we'll move into reporting, showing how to<br>display, summarize, collect, and validate data from a web application. These tutorials are geared to be concise<br>and provide stepbystep<br>instructions with plenty of screen shots to walk you through the process visually. Each<br>tutorial is available in C# and Visual Basic versions and includes a download of the complete code used.
