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.

Using ODBC and OLE DB drivers


First, what the acronyms mean:

  • Open Database Connectivity (ODBC)

  • Object Linking and Embedding Database (OLE DB)

You may already know what these are, and we will not go into detail about how these drivers work on the inside but, in general terms, we can think of them as "query translators", which enable the communication between an application (such as QlikView) and the DBMS. Since they have been in use for a long time, almost all major DBMS vendors provide access via ODBC and/or OLE DB drivers.

Installing the drivers

When you use a printer, it requires you to install a driver on your computer so the documents you send to print can be received and printed properly. The same is true with the DBMS drivers. You need to install the corresponding driver on the machine you will be sending queries from in order for them to be accurately translated and properly processed by the DBMS, which will, in time, respond to it by sending the requested set of data.
