Some 86 percent of enterprises that are using or planning to use a systems integrator through the beginning of 2004 for a Web services solution will use XML, according to a survey by Gartner, Inc. In March 2003, Gartner conducted a survey of 161 North American enterprises via Web and e-mail to determine Web services adoption in in-house projects as well as in systems integration engagements. According to the survey, internal integration with applications and processes is the most common activity or function for Web services projects. Following closely are security, personalization and Web content management. Gartner defines Web services as end-to-end application software that interoperates with other software through a family of XML interfaces – like SOAP, UDDI, and WDSL – to perform useful functions. www.gartner.com
