Ingo from ArangoDB: Despite it's the whole dataset of a real-world use case. :)

We currently look into it. Thank's for the mirrored page.
But as there is no independent institution that compared our product and as we want to know where we stand with ArangoDB, Claudius did his own tests. And as the work is already done, why not share it.
We tried our best to do it as open as possible. PostgreSQL performed very well and we have a problem with memory consumption - have a look at the charts, we will try to improve there.
- Every database configuration is public
- All test scripts are available on Github
- We publish updates if we get pull-requests or comments with suggestions for improvements
We did that before and after the last test, some database vendors sent us improved snapshots of their databases which found their way into the latest products (OrientDB and Neo4j).
If you have suggestions for improvements, please let us know.
But it's not the cheating story of VW, continued - that was about nitrogen oxide pollutants which was up to 40 times above what is allowed in the US.
From the report:
> All carmakers have been exploiting ever more flexibilities in the current official tests during 2013 and 2014, but detailed results from Spritmonitor in Germany (Figure 4) show that cars produced by Daimler, PSA and GM exhibit the largest realworld gaps, around 40%. However, in the past two to three years all major carmakers (with the possible exception of Fiat) have become more adept at using flexibilities in the tests such that all carmakers now have an average gap of 25% or more (as against a maximum gap of only 10% in 2001).
As I understand "Spritmonitor", as a private person, you can record your fuel data (from your receipt) and your odometer to calculate the mileage you can go with your car. No details about the driving behavior that has an impact on how much CO2 is emitted.

I guess that's not the perfect, reliable source - everyone can use the portal and add his favourite car. But for sure, I'll never reach the official 5.7 l/km with my car ...
That could be the name in a particular game or other data from the users profile. Or - limit the leaderboard by filtering on age, region or whatever.
They had only open-sourced the SQL-Layer on top of their key/value store and it's still available on Github. The reason: They build it based on open-source code
When someone deletes a public repository on Github, one fork remains as the new master. (Here's FoundationDB's SQL-Layer: https://github.com/louisrli/sql-layer)
So: RethinkDB will stay, even if someone tries to pull the plug. Just fork them on Github. :)
I've used it to check if a codecanyon / themeforest template is clean enough to start a deeper investigation.
Nice.
node.js and angularJS tutorials might help to get started right away, without any book to read.
Ever thought about a multi-model database like Orient or ArangoDB? The latter allows multi-collection JOINS on documents and graph's and is extensible by Javascript.

Why is it cool?
You start with a few requirements, than learn something new about your business and your customers every day.
With the multi-model approach of ArangoDB you can adapt and change your data model, join between edges and documents and even extend the database by Javascript.
