There will come a time in your QlikView load scripting endeavors where you will need to map a single key value to a lookup table and return the lookup value. If you’ve ever wanted a Qlikview function that is somewhat analogous to a CASE statement for simple lookups/transformations, then look no further than the ApplyMap function.
My video breaks down the hard to interpret user manual definition and provides a simple example that will have you performing QlikView lookups in no time.
If you’ve ever had to put together a quick timeline to share with someone without the need to resort to full blown Microsoft Project then you will find this video helpful. I will show you how to create a very simple but effective Gantt chart that will satisfy your inner project manager. Definitely keep this tip in your Excel toolkit.
For those of you that are familiar with Tableau, you know that sorting can be an exercise in frustration and futility. Fortunately when you understand how Tableau intends its sort functionality to work, you’ll discover that there is a method to the madness. My video presents a simple solution that will alleviate your sorting frustration and should find a place in your Tableau toolbox.
Data Profiling is necessary when trying to gain an understanding of a given data set. A data profiling assessment should begin before any reporting or application development work begins. My video will demonstrate how to create a basic SSIS Data Profiling Task using SQL Server Data Tools.
According to the DAMA Guide to the Data Management Body of Knowledge:
“Before making any improvements to data, one must be able to distinguish between good and bad data…. A data analyst may not necessarily be able to pinpoint all instances of flawed data. However, the ability to document situations where data values look like they do not belong provides a means to communicate these instances with subject matter experts, whose business knowledge can confirm the existences of data problems.”
Here is additional information direct from Bill Gates’s former startup outfit regarding the types of data profiling tasks available in SSIS: https://msdn.microsoft.com/en-us/library/bb895263.aspx
I recently earned a verified course certificate from Coursera in the “Data Visualization and Communication with Tableau” class. This class is the 3rd offered in the “Excel to MySQL: Analytic Techniques for Business” Coursera Specialization. I’m looking forward to taking a couple more MOOCs dealing with Tableau and visualization to supplement and reinforce existing knowledge. I would recommend the class to anyone looking to frame an analysis and learn a good bit about using Tableau.
