Dion Hinchcliffe writes "Ajax hasn't even been big a year yet and already open source development tools by the dozen are pouring out. Not to mention big names like TIBCO and Microsoft already have previews on the way of full-fledged IDEs for developing Ajax applications. Ajax may be the biggest software development story of 2005. Dion Hinchcliffe has a detailed article about how Ajax has evolved over the last six months and assesses the current state of tools, libraries, and mindshare. He also points out that Ajax will inadvertently end up being a driving force for Service-Oriented Architecture (SOA) for many organizations since it requires high performance back-end XML services."
