Hi there, I'm Wesley - Business Intelligence Consultant at Bitmetric since the beginning of 2014. With my non-tech background in Business Economics and Organization Sciences, I'm now developing technical skills and knowledge of data visualization, especially within QlikView. Via this blog, I will share interesting features that I come across. You can follow me on Twitter at @smitwuith1990.

What I learned about Qlik Sense security

It's like a big wall, but for Qlik Sense, and it actually makes sense.When comparing Qlik Sense to QlikView, the most obvious differences are on the front-end, with its completely overhauled and fully responsive design. Other major differences are the server-based development, the use of Master Items and the shift towards APIs, mashups, extensions and widgets.

Somewhat less prominent, though very deserving of your attention, is the security model in Qlik Sense. This has a completely new approach compared to QlikView, and you can pretty much create endless variations. Rather than hacking stuff together and hoping it works, my colleague Rik and I recently decided to take a more structured approach and do some R&D on Sense security rules. Our goal was to gain more understanding of security in Sense, develop methods for gathering and modeling security requirements and to design reference patterns for common implementation scenarios.

We will be sharing some of the methods and patterns that we came up with in an upcoming white paper. In the mean time, I’d like to share with you some of the little interesting, strange and otherwise noteworthy things that we found. These range from basic to slightly obscure, but all should hopefully help you get more understanding of Qlik Sense security rules. Let’s start with noting that the approach in Sense is totally different than it was in QlikView…

QlikView functions – a few to spice up your front-end!

Hello all! It’s been a while since my last post, so here I am trying to catch up with you guys again…

In the pastfunctions 2 few months, I came across a couple of functions which I hadn’t used before. Discussing these with Barry, he mentioned that Rob Wunderlich has done a Survey among QlikView Developers and created a list with functions and the frequency of them being used. Looking at that list, I will try to clarify what some of the functions do in a clear and easy example. Also, I will – hopefully together with you – try to figure out why the hack they’re positioned that low!

Introduction to alternate states

QlikView Alternate StatesA little while ago, I was asked to change an existing QlikView Application. While scanning the application, I found that it used Alternate States. I had already heard about Alternate States, and that they could store different user selections, but didn’t have any hands-on experience yet. I decided to dig a bit deeper into the subject before continuing. I wrote down what I learned in this post

Linked bar charts

Two questions from business users that will probably sound familiar to most QlikView Developers:

“We currently use this report. Can you re-make this in QlikView?”

and

“Our graphics designer came up with this dashboard. Can you do that in QlikView?”

Quite often you’ll find the answer to be yes. Although admittedly, you often may also want to suggest another approach, especially when asked the first question.

Recently I was asked if the following chart could be built in QlikView:

Linked Bar Chart - The Challenge

As you can see, this chart compares relative-to-total amounts for two periods. There is a vague area that connects both bars and kind-of-but-not-so-much shows the change between the periods. I had to think a bit harder before responding to that question…
