Additional tools

There are two bulletins in NTUH, administrative and system bulletins. The administrative

bulletin focuses on NTUH news, announcements; the system bulletin addresses HIS

maintenance. Two bulletins need to be rendered within a web page margin. In addition, the

bulletins require supporting the on-line modification features. The NTUH system

administrator can insert, delete, and update the bulletins frequently in real time. Any

alternation of the bulletins ought to be logged into a database promptly. When a user enters

into the portal, the main page will dynamically, immediately retrieve information from the

database and display on the page.

Moreover, the portal provides two tools: site map and download template. The site map is

generated automatically, accordingly by the portal configuration files. The map will be

updated while the portal is being altered. When a user activates the site map function, the

map can be spontaneously regenerated based upon the newly configured features stored in

the configuration files. In other words, the site map is maintained correspondingly by the

portal configuration files. The function supports “shortcuts” to improve linkage targets

searching temporally and spatially. Furthermore, the administrator can utilize the template,

created from a web page, in order to construct the download page to announce special

issues, meeting memorandums, etc. uploaded as files in NTUH.
