Much of this tutorial will be based on case studies from designs if two sites for sun microsystems: the external one (www.sun.com) that is freely available on the internet and an internal one that isonly accesible to employees.

Thebeaty of hypertext is that the user can then browse the information space futher and dive deeper into the specific informatión of interest to that individual user.
