Distributed Data Applications with ASP.NET

by David Sussman and Alex Homer

This book concentrates on the use of ASP.NET 1.1 and Visual Studio 2003 to build applications for Internet or intranet use, and looks at the possibilities that rich clients bring to both application design and a better user experience. In particular, the authors provide guidance through a range of ideas on how data can be used to drive Web applications, and how that data can be most effectively utilized at each level of the design. They take a...

Hands On Training

Hands-on, example-based training for Microsoft .NET is offered in this book. It discusses .NET's effectiveness in a distributed environment with n-tier architecture, including different types of clients (rich clients and .NET clients), different types of browsers (including Wireless Markup Language (WML) and browsers for wireless devices), a middle tier (executing the business logic), and different types of data sources (databases from different vendors, data streams, and Extensible Markup Language (XML)). The book will be useful for any .NET developer.Chapters 1, 2, and 3 cover how distributed data can be accessed using ADO .NET, including classic ActiveX data objects (ADO) techniques, DataReader, and System.XML classes. Chapters 2 and 3 contain example code supporting the discussion in chapter 1. Chapter 3 is completely devoted to XML data. XML is very popular for representing and storing unstructured data in the Internet-dominated world; this chapter brings out the power of .NET in handling XML data, increasing the usefulness of the book.Chapters 4, 5, 6, and 7 focus on various client-side technologies, including remote data service, .NET Web service, Hypertext Markup Language/Wireless Markup Language (HTML/WML) form and control elements, XML, and others. The motivation of these chapters is to help a developer to identify how much can be done on the client side, including "1. different techniques for managing data on the client, 2. how one can remote data to the client in different ways, 3. [how to] determine the client device type and serve appropriate pages, and 4. [the] type of information that is exposed by different types of client." Chapter 6 focuses on browsers with XML support. Chapter 7 focuses on .NET clients, free from any Web browser running on Windows.Chapters 8 through 13 describe techniques (provided by .NET), with examples and code for "pushing updates (and cashed data) back to the data source," handling of multiple concurrent users, and reconciling update errors, with different types of clients.The authors bring forward an interesting topic, with the comment that "Web browsers weren't designed to be an application platform." They think .NET provides a richer application environment than a browser does, and, given a chance, developers must use "the richness that a Windows application can provide, especially in a corporate environment where [the] .NET framework can be available in every machine" (page 347).These statements give readers some indication about Microsoft's strategy regarding their free product, Internet Explorer, and their new, upcoming .NET framework-based moneymaking Windows operating systems. It will be beneficial for Microsoft's bottom line to make their browser weaker, and to create a new Windows OS (with a .NET client) that will allow for the combination of office, search, and other applications with .NET, making a powerful combination that will be hard to beat with any browser-based application. If the strate
