Demo: QlikView Dashboard

In this demo, I use sample sales data and build QlikView dashboard to create data visualization and help business quickly explore insights and opportunities.

Built with QlikView

I put together to demonstrate a fact table with multiple levels of granularity.

I used four excel spreadsheets (Order, Product, Customer, and Salesperson) as data sources. After manipulating data with scripts, I developed various charts in Qlikview to get business insight.

Besides, I created a quick demo of the dashboard, so you can see how it works without download the Qlikview desktop.
