I’ve been around software for 20 years now. Looking back, I have mixed feelings about the progress we’ve made. The end results have been amazing but the process of building software hasn’t fundamentally changed since the 80s. In fact, I see us make some of the same mistakes over and over again. One of the common anti-patterns is over-relying on tools and frameworks instead of inventing new programming models. Layers of abstraction are fundamental to software. Some layers are defined through programming models, e.g., machine language, assembly language, 3GLs, JSP. Others are defined through a combination of tools and frameworks, e.g., MFC and Visual Studio on top of C++. There is a limit to how high we can raise a level of abstraction through tools and frameworks alone. At some point, a new programming model is the best way forward. Here are some examples: CASE tools ... (more)

RIA Debugging: How to Improve the Life of RIA Developers

This is a call to action to everyone building clients, servers and frameworks for rich Internet applications (RIAs) to improve the life of RIA developers by improving the debugging of backend services RIAs depend on. I’d like to thank the people who’ve offered valuable feedback and additional information that I’ve integrated here. Motivation The relationship of an RIA to its backend is quite different than that of a traditional Web application. In a traditional, dynamic HTML generation Web app, the output stream is under the control of the developer and the application server. D... (more)

The Evolution of XML Protocols

XML protocols can be broadly classified into two generations. First-generation protocols are based purely on XML 1.0. Second-generation protocols take advantage of two revolutionary XML standards - XML Namespaces and XML Schema. This article analyzes the reasons why we need to make a shift to second-generation protocols, and looks at industry activity in this area. First-Generation XML Protocols Generally speaking, protocols specify in detail how certain business/application/network services are accessed through a set of requests and how responses/replies are received. XML protoco... (more)

Private UDDI Registries

This article is based on the UDDI chapter in Building Web Services, to be released this month. It appears here in slightly different form by permission of the publisher, Sams. Contributors to the book are Doug Davis, Steve Graham, Yuichi Nakamura, and Ryo Neyama from IBM; Toufic Boubez from Saffron Technology; and Glen Daniels from Macromedia. The last issue of XML in Transit focused on the categorization and classification capabilities of UDDI. This month we look at the means for customizing the power and flexibility of UDDI for your business through the use of private UDDI reg... (more)

The Standards Democracy

There's been much recent controversy about the role of Microsoft and IBM in the evolution of Web services standards. At a conference I attended not so long ago a pundit talked about the "standard setting duopoly." Several articles have been written about the "undemocratic" practices of WS-I. Are things really that bad? Here's a somewhat cynical overview of the Web services standards process. MS and IBM pick an area of standardization. They cooperate privately on core concepts. They select a third partner to help them flesh out a draft specification. The partner is chosen accordi... (more)
