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.

Extracting data—two hands-on examples


In this section, we will go through the steps required to extract data into a QlikView document. The extraction process through which we pull data into the QlikView document consists of:

  1. Connecting to the database

  2. Querying the database

  3. Reloading the QlikView script

We will provide two examples of data extraction using two different data sources:

  • A Microsoft Access database

  • A table file

Extracting data from MS Access

Our first example will demonstrate how to extract data from an MS Access database. It will be a good example since the connection process is very similar to that used when connecting to most major DBMSs. We will be using one of the drivers discussed in the previous section, and covering the steps required in the entire process.

Note

Before continuing, make sure a database file named Dimension Tables.mdb is in the Data Files\MDBs folder. If not, proceed to create the folder, if necessary, and copy the file.
