It may happen that we work with really big tables that are not just a few rows but millions or even billions of rows. Tableau’s VizQL’s SQL (what a beginning of a sentence!) has to query all these tables, and that takes time. When we...
From here on out (at least for a few posts), we will have a look into the Performance Options of Relationships that are shown when we design a relation between two tables. If you have no idea what I am talking about, chances are that...
In my last blog, I showed you how to iterate through a variable to bring multiple tables into the raw layer of your data warehouse. Today, I’m going to build on that concept by creating a DIM table and performing an UPSERT. Now, to start,...
The new data model brought us the Logical Layer, from which we can draw specific tables without being forced to load the data from all the related tables. Remember, with traditional joins, all sheets that worked with that join had to load the full data...

Information technology is one of the world's fastest growing sectors. Data, analytics and technology have permeated through all aspects of our lives, and it is safe to say that in all sectors and industries, there are data problems to be solved. Just in Australia, the...
Of the many useful functions available in Snowflake, one of my favourites is the GENERATOR function. This function allows you to create rows of data from nothing and can be useful in many ways. Any time you don't have physical data to get you started...
