QlikView 11 for Developers

Overview of this book

Business Intelligence technologies are a must-have in every business to make informed decisions and keep up-to speed with the ever-evolving markets. QlikView's disruptive technology makes it a key player and leader in the industry; with its flexibility and powerful analytics environment, building QlikView apps can be mastered by both, business users as well as developers. This book will help you learn QlikView Development from a basic to a practitioner level using a step-by-step approach in a practical environment, and apply proven best practices on each topic. Throughout the book, we will build a QlikView app based on real data about Airline Operations that will help "HighCloud Airlines" make informed business decisions and analysis-guided strategies. HighCloud Airlines executives are evaluating if entering the US market is a good strategy and, if so, which line of business should they focus their investments on; they need QlikView to make the best decision. The application will be evolving chapter by chapter, along with your skills, going from a simple proof of concept to creating a Data Model, adding a custom style, building a Dashboard and handling and manipulating the source data via script. We will meet the "HighCloud Airlines" requirement by using many different data visualization objects and time-saving techniques. The whole application uses real data taken from the Bureau of Transportations statistics of the US and encompasses the operations of Airlines both domestic and international. With three years worth of data, you will help HighCloud Airlines discover where people travel the most, which are the Carriers with the most market share, what is the average load factor per airline, which aircraft is the most used to perform flights, which are the busiest airports, and a whole universe of new insights.

Chapter 14. Security

Until now, we have focused our efforts on getting data into QlikView and presenting it in dashboards, analyses, and reports. Our documents were open to anyone with access to QlikView. As QlikView documents can contain huge volumes of sensitive data, in a real world scenario, leaving your data unsecured might be a very risky proposition.

In this chapter, we will focus on how we can secure our QlikView documents. We will first look at how we can make parts of the script only accessible to a limited group of developers. Next, we will see how we can ensure that only authorized users have access to our document. We will finish this chapter by looking at how we can set different permissions for authorized users and can limit which data a user can interact with.

Specifically, in this chapter you will learn:

  • How to create a hidden script that is only accessible to a select group of developers

  • How to allow only authorized users to open your document

  • How to limit what a user can do...
