QlikView Publisher is used to load the data from Sybase. Publisher’s loop and reduce<br />

capability is used to create several QlikView applications from seven master QlikView<br />

applications based on the sector information found in the data. The sizes of these seven<br />

master QlikView applications range from one to three gigabytes. Publisher’s loop and reduce<br />

capability simplified the maintenance of the QlikView applications for the IT department as<br />

these are the only applications that they should maintain and make changes to. Publisher<br />

automatically creates the sector based versions of the applications after each data refresh.<br />

QlikView Developer is used to develop the data extraction and transformation as well as to<br />

develop the graphical user interface. As the business user access required no installations,<br />

AJAX Zero- Footprint Client is used for business users accessing QlikView applications on the<br />

QlikView Server from the extranet.<br />
