SFBannerThe bird is in this photo is not a seagull. She’s an earlybird, headed to masterssummit.com to take advantage of the earlybird registration discount available until February 27.

At the Summit, birds of the Qlikview Developer variety will be immersed in three days of hands-on advanced and intermediate QlikView Developer training. We’ll be covering topics such as advanced scripting, advanced expressions & aggregation, visualization, data modeling, performance, server administration and Qlik Sense for QlikView  customers.

Training will be led by four popular instructors, all well known as Consultants, Bloggers, Qlik Luminaries and longtime QlikCommunity contributors.

Barry Harmsen: Co-author of the seminal book “QlikView 11 for Developers” and founder of the Q-on Training Center.

Oleg Troyansky:  Author of the upcoming “QlikView Your Business” , QlikView veteran and one of the all time top contributors to QlikCommunity.

Rob Wunderlich (hey that’s me!):  Publisher of QlikViewCookbook.com and founder of the QlikView Components open source script library.

Bill Lay: Visualization wizard and everyone’s favorite presenter. Bill’s entertaining  presentation style makes any topic interesting and engaging.

In addition to the class material, we’ll have an evening panel discussion, guest speakers and plenty of opportunities to network with peers.

Qlik Sense Opportunity for QlikView Customers

I had a great time participating in the Hackathon at the recent Qlik World Conference in Orlando. The Hackathon challenge was to create a visualization solution to a United Nations challenge using the Qik Sense Mashup APIs. It was a stimulating exercise for a number of reasons — the subject matter, the company of talented practitioners, and the Sense API ease of use and powerful functionality.

Through my experience with using the APIs and talking with a number of customers at the conference, I see a clear opportunity for existing QlikView customers to leverage Sense as an Extranet or Mashup solution.

Many QlikView customers have apps that currently deliver great value inside the company. These apps may be mature, data dense and backed by a sophisticated data model. Everyone is happy, but there may be some discussion about providing a subset of the solution to external users like B2B customers over the web.   That has been  possible with QlikView, but it can be to be complex to implement. It’s much easier with Sense and I think Sense could be the killer solution for extranet reuse. Here’s why:

  • The existing QlikView data model can be reused by Sense with a simple Binary Load. No need to write additional script and you maintain a single-version-of-truth for both internal and external users.
  • The sense charts and visualizations are much more “webby” in appearance and behavior,  meeting the modern expectations of web users and web developers alike.
  • The APIs are powerful, clearly designed and will be easily understood by web developers tasked with integrating Qlik content and data into portals or other  interface.
  • Better APIs to get data from the Qlik engine. For example, there are methods to create and return “hypercubes” of data. Pass in Dimensions and Expressions and calculated data is returned — without the need to create a chart. The returned data can be visualized or used to drive another process.
  • The new Session Authentication API can delegate user authentication to an existing portal session, eliminating the need for a piggybacking WebTicketing exchange. This satisfies the common customer requirement that “when the portal session ends, the Qlik session should end”.

You can follow updates to the Cookbook in a couple of ways:

Using Alerts to “Send the Numbers”

The Qlikview Document Alert feature is generally thought of as a way to notify users or administrators of exceptional conditions in the loaded data. But it may also be used for regular emailing of non-exception conditions, like daily sales figures. This can be very useful to inform mobile or travelling user of the status of Key Performance Indicators.

The Document Alert feature is part of basic Qlikview. No additional software or license is required. Please note that that Alerts can only send out text email. They cannot send graphical charts or attachments. If you want that  functionality, look to third party addons such as NPrinting.

Alerts are configured in a QVW using the menu item: Tools, Alerts. The Alert Message may contain dynamic (calculated) content in the form of an expression like:

=’Sales YTD:  ‘ & money(sum({<Year={$(=year(max(OrderDate)))}>}OrderAmount))

I won’t go deep into the configuration details here, because I’ve provided a downloadable annotated example at this link:
Qlikview Cookbook: Using Alerts To Send Numbers Via Email 

The example will produce an email after reload that looks like this:

Alerts are a low cost and simple way to expand the reach and value of your QV applications. Users receiving emails do not require a Qlikview license.

Welcome to the Qlikview Cookbook Online!

In 2008 I published the first edition of the “Qlikview Cookbook”, a downloadable collection of Qlikview examples designed as a reference and training tool for Qlikview developers.

The last update to the Cookbook was in 2011 and  it has been downloaded from RobWunderlich.com over 20,000 times.

It’s time for a major update to the Cookbook. For the update I’ve created this website as an expanded delivery vehicle. In using a website, I hope to make it easier for you to discover relevant examples and make it easier for me to maintain.

I’m still open to creating single-file archives of most content — like the old Cookbook — if there is demand for it.

Quick Tip for Exploring Your Data Model

I picked up a great tip from QlikCommunity to view field values in your data model:
http://community.qlikview.com/thread/89396

I refined it a bit and am finding it very useful.

1. Create a listbox for field “$Field”.
2. Create a Straight Table Chart with:
  a) Calculated Dimension:  =$(='[‘ & only([$Field]) & ‘]’)
  b) Expression:  =sum({1}1)

Select a $Field in the listbox and the field values and frequencies will appear in the chart. Very handy for exploring data values in your model.
