Apple will be demonstrating PowerSchool, their Web-based student information system (SIS), in the 4D vendor booth in the WWDC Exhibit Fair at the Apple Worldwide Developers Conference, which will be held June 28-July 2 in San Francisco, CA. 4D’s integrated Web capabilities have allowed PowerSchool “to completely Web-enable their applications, providing easy access to student information for everyone involved in the learning process, all through a Web browser,” 4D officials said.
