The Agile Data Warehouse™ Story
Posted by Larry Hill on Tue, 01/12/2010 - 09:05Next-Generation Business Intelligence?
There are numerous articles and discussions on the web about next- generation BI. Industry analysts talk about the need for MDM and data governance standards and strategies to form the basis of the next generation of BI. We believe that this focus is mostly in response to the disorganization of systems that have been built with traditional BI and data warehouse tools.Migrating a Linux S3 Based AMI to an EBS Based AMI
Posted by Rohit Amarnath on Mon, 12/07/2009 - 21:05While we have been booting from EBS a month after it came out using pivot_root - most of our implementations are based on a couple of AMIs and many different EBS snapshots and volumes. We were nonetheless happy to see Amazon's announcement to allow AMIs to boot from AMIs, it makes some of our scripts much simpler. I put this article together to show migrating an existing Linux AMI to EBS can be a trivial task.
Extracting Government Spending Data via Talend and Ruby into CouchDB
Posted by Rohit Amarnath on Sat, 04/11/2009 - 23:45Note: To make it easy for anyone to get access to this data I chatted with the good folks at Amazon to expose all the data (both couchdb files and csv) as a public data set! I will also share an ami that you can spin up and use to start looking at this data almost immediately. Look for a post on that soon.
HOWTO: Share the EVDO internet connection on the Mac with the first gen iPhone
Posted by Rohit Amarnath on Mon, 03/02/2009 - 22:11This post will have nothing to do with Analytics or Data Warehousing but I had such a tough time getting this to work that I figured I'd publish a post on it.
Creating a Just enough OS (JeOS) EC2 Image for Oracle Enterprise Linux
Posted by Rohit Amarnath on Mon, 12/22/2008 - 03:41I have always been a fan of stripped down "just what you need" OS installations of Windows and Linux. Which is why we use nLite for creating custom XP builds and gentoo for general purpose linux machines. For Oracle applications we use a base installation of Oracle Enterprise Linux.
The advantage of a these minimal builds are:
- Better Performance
- Smaller Footprint
- More secure (in theory)
This has worked well for us - our hosted instances boot in a minute or less.
Installing Oracle Essbase 11.1 on Linux/Unix
Posted by Rohit Amarnath on Mon, 11/24/2008 - 00:20Ah the joy of installing Essbase on Unix. Even better installing it on Linux. Installing on Linux took some doing. So with some fits and starts, a major doozie and some finagling, we have an instance running Oracle EPM 11.1! If any of you folks out there want to play with 11.1, shoot us a note and we'll hook you up.
Oracle EPM (Hyperion Essbase) 11.1.1.1 for all Platforms Released
Posted by Rohit Amarnath on Sat, 11/15/2008 - 19:40Oracle has finally released EPM (Essbase) 11.1 for all platforms. Thanks to Ed Roske at Look Smarter Blog for the heads up!
We have started the process of building and testing the 32-bit and 64-bit (yea!) versions of Linux and Windows. Once we have that up, I will post an update on what we find in our testing.
Reporting and Analytic Applications for pennies using Cloud Computing
Posted by Rohit Amarnath on Tue, 10/28/2008 - 19:42Some of our more cutting-edge clients (thanks Dave!) asked how we might help them leverage Cloud Computing to host their applications. The advantages of cloud computing are easy to see because the cost of storage and computing is measured in pennies per hour/gigabyte and works especially well for reporting and analysis applications.
Here are some examples (a la Mastercard style!)

The advantages of doing this include:
