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 3. Data Sources

We've completed the "Seeing is Believing" phase with big success. We've shown HighCloud Airlines the potential value that QlikView can bring to their business and how they will be able to give their raw data the meaning their business requires to make everyday decisions. Now, the natural question that arises after seeing what QlikView can do on the frontend is: What type of database does QlikView require to work?

The straight answer to this question is, simply, that QlikView does not necessarily requires a specific database or Data Warehouse (DWH) to pull data from. It could benefit from using a DWH, but it is not required. However, the data must reside somewhere, in order to be able to pull it into QlikView, visualize it, discover patterns in it, and build all kinds of charts with it. That somewhere can be almost any standard database, flat file (for example, .xls or .csv), web page, and so on, or even any combination of the above.
