I frequently hear the question, “Can Tableau show my missing data?”. Generally when I get this question, people want to either see a 0 or a blank where there should be missing data.
Have you ever found that Tableau Desktop took a long time to load a worksheet or apply a filter? You might have found yourself wondering “Is my data source too large for Tableau?” The answer is…“maybe”.
If you’ve been using Tableau Desktop for a while you probably know that you can join, union and pivot data in the product. When you hear that Tableau Prep helps you “prepare your data” you might wonder what it can do that Desktop can’t.
Tableau Desktop will allow you to union multiple tables from the same database or even multiple .csv files, but you can’t union a table from SQL Server A with a tableau from SQL Server B.
Tableau Prep is a powerful tool but it can’t help solve every data preparation scenario. We focus a lot of our time and effort on what it can do, but we thought it would be worthwhile to cover what it can’t do (yet).
Joins can be a sticky business, especially if…
● You haven’t used them much before.
● You are working with data that is new to you.
● You don’t trust your data cleanliness.
If you're like most people in the world of analytics you spend 90% of time cleaning and preparing data and the last 10% recovering from the effort. Not anymore!
Join us for 30 minutes to look at how you can use Tableau Prep to clean dirty data and save hours each week.
