Get started with tableau prep2/29/2024 Simply put, apart from a few great blog posts, there were limited opportunities to regularly practice using Prep Builder or work across a wide range of different industries’ challenges. Jonathan, a new Data School consultant, questioned Carl, the ‘Other Head Coach’ at the Data School UK, as to the best way to start getting more hands-on practice with Tableau Prep Builder. It was also for the ‘Dr Preppers’ (Jonathan and Carl) as the initiative started with a conversation over a coffee machine at the Data School where it quickly became apparent that others would benefit too. Preppin’ Data wasn’t just for the people participating in the challenges. This is why self-service data prep is so important. It was also compounded by data sources now living on the internet, behind APIs, on PDFs, and more. This challenge is not limited to business data. Data was hard to source and hard to load into the tools that business users and analysts were already using to answer questions. The informal wrangling burned hours of people’s time on an uninspiring task that would just have to be repeated again the next day, week, or month. Those that could, simply didn’t have the access or permission within the database to write the queries.įor the informal data files, wrangling the data involved a lot of copying and pasting or deleting rows and columns. Most business users and business-side analysts simply didn’t know how to write SQL. The formal “wrangling” of data to complete analyses involved writing SQL code within the database itself. Traditionally, this was formally done within databases by IT teams within organizations, but also informally within Excel workbooks. Let’s dive into why self-service data prep is important for individual analysts and organizations, along with some further lessons learned from our time with Preppin’ Data.ĭata is everywhere but to make use of it as analysts we first need to gather, structure, and clean the data. These projects explore various facets of data preparation and aim to not only provide realistic examples of data preparation problems, but also keep participants on the cutting edge of Tableau Prep Builder releases by highlighting new or interesting features. During the week, participants share and discuss their ways of tackling the problem and the following week, a possible solution is released. ![]() Each week a set of data is released along with a series of requirements and end-goal of how the data needs to be prepared. This is a lesson we’ve learned with the launch of Tableau Prep Builder and now with our Preppin’ Data project - a weekly project designed to get people hands-on with data preparation. You can also more easily validate data sets to be sure that you are accurately reflecting reality. You can greatly reduce your analysis time when you can produce the datasets yourself. Adding additional data sources helps answer further questions and allows the data worker to provide more context to the consumers of their analyses. Self-service data prep is an extension of the same paradigm as self-service analytics: allowing people to answer their own questions with data that was previously inaccessible.
