Is it just me or is Periscope allergic to saying what databases it supports? I can find nothing on the website, and I am really hesitant to sign up for more info once companies started actually calling my phone after I did that. Also, none of those queries will work on MySQL.
They support Postgres, Microsoft SQL Server, Redshift, and Oracle I believe.

The blog content is good though

Is it just me or is Periscope allergic to showing the "Pricing" page? (SaaS anti-pattern) Or is it free? The blog content is good though

`jplitz and `ajones are right. As of now we support MySQL, Postgres, Amazon Redshift, Vertica, SQL Server, Oracle, MemSQL, Sybase, Exasol and Google BigQuery. We add more all the time.
More please.

That said, I do have one major gripe with their sales process: Their free trial lasts 7 days. There is no way a company can evaluate a completely new BI system in a week. I begged and pleaded and they would not extend the trial.
I'm not just saying this, but I really really do think we would have bought it if we could have had 30 days. I just can't build enough organizational momentum to spend money on a new system in 7 days.
The big caveat with the standard deviation technique is that it assumes a normal distribution. Many datasets are not actually distributed normally (power-law, Poisson, beta, etc, etc) and so the technique won't work. It's a much harder problem to 'generically' detect outliers without knowledge of the underlying distribution.
I don't have any idea how to do it (though a former colleague came up with nice idea of building a histogram and searching for values that occurred after some number of empty bins, implying an outlier). Is there an accepted state-of-the-art for general-purpose outlier detection? Or is that such a broad question as to be meaningless?
What are credit card companies doing? What's the best way to combine multiple variables that are predictive of an event for outlier detection? Is there a simple framework to automate reporting of these events in real-time?
One way to model this might be to treat the outcome ("Is this event an outlier?") as a 0/1 variable and use one of the many ways to model that type of data–random forests, logistic regression, neural networks, etc. The problem is that this isn't really "outlier" detection anymore.
Earlier quoted context omitted.

I won't blow it by sharing the pricing they quoted me, but I thought it was pretty reasonable. That said, I do have one major gripe with their sales process: Their free trial lasts 7 days.
