TIMONIUM, Md.--(BUSINESS WIRE)--April 17, 2002

RDA, a leader in helping businesses and organizations achieve solutions that leverage technology, today announced that two of their Principal Architects, Lonnie Wall and Andrew Lader, have authored "Building Web Services And .Net Applications," published by McGraw-Hill/Osborne Media.

Microsoft's .NET platform represents a monumental shift in the development of distributed enterprise applications and Web services. By harnessing the true power of XML, the .NET framework enables developers to build and deploy distributed applications and Web services in a fraction of the development time.

With Building Web Services and .NET Applications you will:

-- Gain an in-depth understanding of XML, from XML schemas, to the Document
Object Model (DOM) and XML Templates (XSLT).

-- Learn how to design and build large-scale distributed applications using XML
and SOAP with examples that come from "real world" designs.

-- Take a full tour of ADO.NET and SQL Server 2000 and discover how easy it is
to develop distributed, data-centric, applications that take full advantage of
DataSets.

-- Explore the Common Language Runtime and learn how the Common Type System
plays a critical role in the development of .NET applications.

-- Explore and examine ASP.NET, from building web applications, to consuming
web services, to developing user-defined composite controls.

-- Learn how to build .NET Windows Forms applications that take advantage of
the distributed programming model with .NET and see how .NET applications can
integrate with Java applications through web services.

A webcast with one of the authors is planned for Thursday, April 18th at 11am EDT. For more information on the webcast or RDA, visit www.RDAcorp.com.
