Microstrategy
Analysis and discussion of Microstrategy and its business intelligence product line.
Teradata’s future product strategy
I think Teradata’s future product strategy is coming into focus. I’ll start by outlining some particular aspects, and then show how I think it all ties together.

Microstrategy technology notes
Earlier this week, Microstrategy made Mark LaRow available to talk about technology. The proximate reason was my recent mention of Microstrategy’s mobile BI emphasis, but we also touched on Microstrategy’s approach to in-memory business intelligence and some other subjects. We didn’t go into the depth of a similar conversation I had recently with Qlik Technologies, but I found it quite interesting even so.
Highlights of the in-memory BI discussion included:
- Microstrategy’s in-memory BI data structure is some kind of simple array, redundantly called a “vector array.” A more precise description was not available.
- While early versions of the capability have been around since 2002, Microstrategy’s in-memory BI capability only got serious with Microstrategy 9, which was released in Q1 of 2009. In particular, Microstrategy 9 was the first time in-memory BI had full security.
- Mark says a core reason for having their own in-memory BI is because Microstrategy has more smarts to predict which aggregates will or won’t be needed. Strictly speaking, that can’t be argued with. Vendors like Infobright would argue they come close enough to that ideal as to make little practical difference – but I’m also cheating by naming Infobright, which is particularly focused in that direction.
- Microstrategy in-memory BI compresses data by about 2X. Mark didn’t know which compression algorithm was used.
- The limitation on what’s in-memory is, of course, how much RAM you can fit on an SMP box. Microstrategy has seen up to ½ terabyte deployments.
- In-memory Microstrategy data structures are typically built during the batch window, for performance reasons. This is not, strictly speaking, mandatory, but I didn’t get a sense that Microstrategy was being used for much that resembled real-time business intelligence.
- Mark said Microstrategy has no interest in using solid-state memory to expand the reach of its in-memory BI. Frankly, if Microstrategy doesn’t change that stance, it’s in-memory BI capabilities are unlikely to stay significant for too many years.
Another key subject we discussed was Microstrategy’s view of dashboards. Read more

How should somebody teach themselves database and programming skills?
From time to time, I get in a conversation with somebody who is:
- Unemployed, underemployed, or otherwise desirous of having more commercial skills.
- Not a programmer, but desirous of having some technical skills.
- Astute enough to realize s/he will never be a serious techie.
I generally have two models in mind when guiding such a person:
- Analytics/business intelligence/stats.
- Website building.
Those are both useful skill sets for people who aren’t full-time techies, the first perhaps best for those who are more quantitative and big-company-friendly, the second perhaps better for the creative and/or rebellious types.
So what SPECIFICALLY should one guide them to do? My initial thoughts include: Read more

False-positive alerts, non-collaborative BI, inaccurate metrics, and what to do about them
I’ve been hinting at some points for quite a long time, without really spelling them out in written form. So let’s fix that. I believe:
- “Push” alerting technology could be much more granular and useful, but is being held back by the problem of false positives.
- Metrics passed down from on high didn’t work too well in Stalin’s USSR, and haven’t improved sufficiently since.
- A large, necessary piece of the solution to both problems is a great engine for setting and modifying metrics definitions.
I shall explain. Read more

Microstrategy tidbits
I chatted with Microstrategy Wednesday in a call focused on the upcoming Microstrategy 9. There wasn’t a lot of technical content, but I did glean:
- In Microstrategy 9, virtual ROLAP cubes will be able to draw on multiple relational databases, not just one. (Frankly, I’ve never understood why BI vendors are so slow to put in features like that.)
- Actually, in Microstrategy 9 cubes won’t just be virtual. You’ll be able to instantiate parts of them in memory.
- The in-memory part requires manual intervention. However, that intervention can be as minor as pushing a button to accept the recommendations of a Cube Advisor.
- The Microstrategy Cube Advisor will examine workloads for a month or so to see which queries chew up the most resources.
- Another new feature is “complete” OLAP drilldown from any point in any chart or graph, without pre-programming or pre-specification.
- Microstrategy’s favorite DBMS partners are, in some order, Netezza and Teradata.
- Microstrategy 9 is currently scheduled for March 23 release.
