A static presentation is created from the Charts and Analysis module with the data of the database. When a static presentation is published on the web it remains the same if the data of the database is changed.
You can update a static presentation from the Charts and Analysis module using the Update slides from database function. If you want to update your presentation regularly, use the Scheduler (which updates and uploads the presentation at a specified time interval).
The static presentation is a HTML file that contains images (JPG). You cannot update these images, you can only recreate and upload them again.
The live presentation is a PHP script containing a SWF file (that draws the charts). This PHP script communicates with the database through another PHP script that uploads the data from the database to the SWF file. This way you obtain a real time presentation that is updated with the latest results from the database.
Important: Static presentations are available for each type of database: Microsoft Access or MySQL, but live presentations are only available if the database type is MySQL.
