In the late 1990’s many ERP companies caught the web browser wave, undertaking projects to leverage the Internet and browser technology and even to convert their software to “lite-client” or web “portal” architectures. Unfortunately for some, .NET came on the scene too soon after this major overhaul. When .NET appeared, some were too technically exhausted, or inflexible, or still basking in the glow of their new “Internet-based architectures” to recognize and embrace .NET. Other ERP software companies were and continue to be simply too busy struggling to stay solvent during the devastating one-two-three punch of Y2K, the recession of 2000, and 9/11. They lack the resources to consider the complete restructuring of their products that .NET warrants.

Everybody is now talking about Web 2.0, a Web that is more dynamic, richer, more interactive, and, ultimately – much more exciting than anything we know now. It’s just human nature to look for unusual and new stuff. But, what does that mean for business applications?

Let’s look at Google Maps. Yes, we are all excited by Google Maps. It looks great. It is very interactive. And, most importantly, it behaves completely differently from what we expect to see in a “normal” browser. But, compared to any realistic business application – say something like trivial Internet banking – Google Maps is nothing. It supports just a few use cases compared to the hundreds or thousands of use cases for a typical business application.
