running the queries for the report again. Reports can be scheduled to run and be
delivered to multiple recipients.
Portal
Oracle Application Server Portal has gone through some significant changes in its
history. When it was first released under the name of WebDB, as part of the Oracle
database, Portal was viewed as a tool to create HTML-based applications, a role subsequently
taken by HTML DB, and later ApEx, described earlier in this chapter.
WebDB was renamed Oracle Portal, and the aim of the product was changed to
focus on bringing together separate sources of information into a common desktop.
Entire books have been written on Portal alone, so the description in this section is,
of necessity, a very brief overview of the range of Portal capabilities.
Portal uses pages, which can consist of static or dynamic information, and which use
a theme for overall look and feel. Portal includes wizards for easy creation of pages.
