• Some of the good things in Qlikview are
    • Extension objects for third party visualization. http://www.qlikblog.at/2848/qlikview-extension-tutorial-basic-concept
    • Column level data reduction based on users login (in QlikView we have Section Access)
    • Does not support connectivity with XML data sources.
    • Bookmarks.
    • QlikView can manage much more complex calculations. You soon hit the limit for what Tableau can do.
    • QlikView has their own data file for storage (QVD), which compresses data as 10 times of the original size. There is no equivalent to QVD in Tableau
    • Because Tableau doesn’t have a QVD equivalent, you’re limited by the DBMS in terms of response times.

  • Some of the good things in Tableau are
    • It has native driver for Big Data, salesforce and Google Analytics.
    • It does not have a data handle limitation like QlikView.
    • It provides suggestions of visualization charts according to the dimension and measures. (this is really  a good feature not available in QlikView)
    • It has a free viewer software known as Tableau Reader to view workbooks created in Tableau Desktop.
    • When you’re working in the front-end some tasks like creating charts may take you less clicks than if you try to do the same in QlikView.
    • However, Tableau needs the information as clean as possible in order to present data in dashboards. So in most cases is better to have a Data Warehouse ready to connect or make some transformations in your DB.
    • Provide cloud service.
    • Can embed visualization to a web page.
  • Tableau is easier to use, more intuitive and quicker to learn. Qlikview has more powerful/flexible reporting capabilities than Tableau.
  • You need QlikView if you:
    • Analyze millions of data,
    • Employ IT specialist,
    • Quite often modify analysis.
  • You need Tableau if you:
    • Analyze billions of data
    • Already have ETL tools
    • Employ IT specialist
    • Very often modify analysis
  • Tableau require separate ETL tool but Qlikview do not require any separate ETL tool.
  • Qlikview can produce better reports but it takes more skill and time to develop than with Tableau.
