Enhancing your data team with ours
Our consultants come armed with both technical and soft skills to support you to make the most of your data.
The Data School has been paramount to our success at JLL. It has allowed us to bring in highly skilled Tableau and Alteryx consultants. It saves considerable time trying to recruit contractors as I know their skills and training are to the highest standard. Over the past 5 years my team has developed analytical insights which have generated multi million dollar savings of which a considerable amount can be attributed to the Data School consultants we have had working on projects.

Dynamic selection of columns based on the % of nulls in Alteryx
I was recently working on several data tables each containing hundreds of fields/columns. I later found that many of those fields were entirely, or mostly, null.
Armed with a browse and select tool, I began to check and remove fields that were 90% null or more
