Why? For example, Alteryx is a more mature tool and offers more possibilities. There’s a whole lot of tricks to deal with, but it’s discouraging. As it is a relatively new and very fast-growing tool, mistakes happen. And it works! Instead of powering the Prep flow every day, you can do something else. The alternative is to combine Tableau Prep flows with Windows task scheduler. However, it is a tool licensed separately from Tableau Desktop or Tableau Server and thus available mainly for larger companies. At each stage we can also go back to the previous step and correct it.Īs I wrote earlier, you can use the Tableau Prep Conductor to automate the flows on the server. At each stage, we can view the result both in the table and in Tableau Desktop. And the Tableau Prep is transparent and forgiving. We can edit data at the level of each cell, column and row. Here we can, among other things, deal with many variants of name saving, create index columns, prepare specific measures, delete duplicate rows. These operations in Tableau Desktop are sometimes impossible and sometimes very expensive. The strengths of Tableau Prep are data cleaning, aggregation and processing to the form necessary for analysis. Finally, it is worth remembering that merging tables does not exhaust the possibilities of Prep. Secondly, there are a number of situations where even in Tableau 2020.2 and later, data will be combined into flat tables. So many of us will remain in the old world for some time. This means that their use requires a consistent upgrade of the full Tableau environment in the company. First of all, the relations in Tableau are not transferable to older versions. This, in turn, means a major improvement in efficiency. More smaller tables means that Tableau sends queries to smaller datasets, and only those that are related to the graph being created. You define one field, identical in both tables, based on which Tableau automatically builds joins when the visualization is constructed. Only the relationship between them is then defined. From version 2020.2 onwards, the source tables in Tableau Desktop can be stored separately. Only disabling the merging step from the Tableau Desktop improved efficiency. Until version 2020.1 the demarcation was simple. And in Tableau Prep, and Desktop, we can combine data using unions and joins. This question has become more relevant since the new data model appeared in Tableau 2020.2. When to use Tableau Prep, and when Desktop? Non-standard and complex challenges are published weekly as part of Preppin’ Data. It’s a good way to face up to typical tasks. Then, in addition to explaining the basics, the trainer will show the tool’s subtleties on specific examples. You can also take advantage of the training. By learning you can experiment on your own. These 500 pages also include the Tableau Prep Conductor. When writing this text, the instructions for Tableau Desktop are 3249 pages, and for Tableau Prep are 533 pages. However, it is still much less powerful than Tableau Desktop. Prep has grown and gained a lot of new interesting features. However, it’s been a while since I’ve been able to listen to all the instructional videos for him during the tire change. The idea behind Tableau Prep was to make it simple and intuitive. How to learn Tableau Prep and is it difficult? The answer to this was Project Maestro, which then became Tableau Prep Builder. You may have needed another piece of SQL query or a modification in Excel. For a long time, the preparation of the source meant switching between the Tableau and the auxiliary tools repeatedly. It likes it because well-prepared data improves efficiency and speed of work. And Tableau Desktop likes data organized and kept to a minimum. Where did it come from? We all know that cleaning and preparing data in Tableau is an ungrateful and often inefficient task. Today we will focus on Tableau Prep Builder. The Tableau Prep Builder is used to manage flows from the Tableau Prep Conductor on the server. The chain of subsequent actions modifying our data is called flow here. With its help, data can be combined, cleaned, aggregated, rotated and even processed with R and Python functions. The software we usually think of as Tableau Prep is Tableau Prep Builder. What is Tableau Prep and where did it come from? Today’s post will summarize those questions about Tableau Prep that I hear most often as a consultant. Those who peeked but didn’t work for a longer period of time still have many questions. And yet many people still haven’t had a chance to meet him. It is available for free to most people with Tableau Desktop licenses. It has just been two years since Tableau Prep joined the Tableau product family.
