Pervasive Software Inc. announced at the MACWORLD Expo the availability of the Tango 2000 Web development environment for the Mac OS operating environment. This new release of Tango 2000 enables Macintosh developers to build and deploy e-business applications and dynamic Web sites in the latest Mac operating environment, while leveraging Tango 2000’s advanced, visually-oriented development capabilities to bring applications to market in Internet time. Customer shipments of Tango 2000 for the Mac OS environment commenced in late December 1999, and Pervasive plans to ship a version of Tango 2000 for Mac OS X when Apple releases that forthcoming operating environment. The Tango 2000 for Mac OS development environment includes full XML integration and Tango Class Files (TCFs). By providing developers with full XML integration, XML can be treated as data types inside the Tango application for easier manipulation of structured data. TCFs also give developers the freedom to write code only and then reuse the code as an object in future projects. Tango 2000 for Mac OS is available now. U.S. pricing for the Tango 2000 Development Studio is $495. Application servers are priced separately, starting at $995 for Macintosh, scaling from the small business edition to enterprise-class solutions per individual business requirements.
