Oops, it seems we did it again! After our successful appearance in WHAT datathon, we took part in Eneco’s Data Challenge, a part of Dutch Data Science Week. Our solution won, because it provided the most business value to Eneco. Read our Rax blog post for more details.
Last weekend we took part in the WHAT datathon – a data science competition accompanying the WHAT behavioral data conference organized by Wakoopa. And YES, we won the Gfk Insights track: The challenge was to uncover business insights in clickstream data. We got data of one month in 2016 of a Dutch panel that shows […]
Our SQL-backend family is contantly growing. Rax could already connect to SQLite, MySQL and PostgreSQL databases. Recently we have also ported Rax to two major cloud databases: Microsoft Azure and AWS Redshift. Now we can easily compare the performance of various database systems on behavioral data. Before Rax it was difficult, as each database vendor […]
Programming is hard. There is a lot of complexity that needs to handled. To hide at least some of this complexity, people come up with abstractions. SQL is an example of an abstraction – it provides a way to process data without worrying about all sorts of details like: How to find the relevant data […]

Maybe you also remember that Relational Algebra operates on relations, which are a special category of sets. As such, they do not contain duplicates. An SQL table, however, can easily contain duplicate rows and therefore it’s […]
A nice read: http://robklopp.wordpress.com/2013/08/12/thinking-about-bi-infographics-is-the-next-phase/ The company he mentions, Looker, sounds interesting. They claim to have simplified SQL by adding LookML on top of this. I couldn’t find much concrete info, though. Their website is full of buzz and the free trial requires jumping through many hoops.
I like the slogan. It’s a bit along the lines of how we’re trying to sell Rax: Spinnakr — Data Scientist As A Service The ‘Spinnakr’ data scientist is of course quite limited in its scope: it can only analyze web traffic and search for a number of patterns. However, it these patterns happen to […]
I stumbled upon a new buzzword: wide data 🙂 I must say, I’m getting lost in the financial jargon, but it’s an interesting read nevertheless.
