OpenMRS stands for 'Open Medical Records System', and is a major open-source project aiming to build medical information systems for developing countries. Their general goal is to provide a low-cost (free) solution for tracking patient conditions. Their specific goal is to fight AIDS in Africa.

Their website is http://openmrs.org/wiki/OpenMRS.

The project is gaining a lot of momentum. They have strong links with organizations such as the World Health Organization (WHO), corporate sponsorship from companies such as Google, and are already deployed in 12 countries.

The OpenMRS architects are are in the process of adding analytics using mondrian. I have committed to helping them out, and Matt Casters (architect of Pentaho Data Integration aka Kettle) is also …

One of open source's Achilles' heels is its lack of true outreach to end users. I'm not a developer. As such, I have very little influence over how OpenOffice, Linux and MySQL develop. I suppose I could request features, but how? And, more to the point, how do I derive maximum business value from the open-source projects that I use?

Actuate may have an answer to this quandary. Actuate just announced the rollout of an innovative open-source community, called BIRT Exchange, focused on open-source business intelligence. I talked with the team today and was impressed by this new community model.

Released in 2004 as a project on Eclipse, BIRT has steadily grown in importance and adoption with Eclipse. Actuate hopes that the BIRT Exchange will focus this adoption even …

My friend and colleague Julian Hyde of Mondrian fame just blogged about this: help out the OpenMRS project , please!

The folks behind the OpenMRS are helping to improve the health-care systems in developing countries. More in particular, they are fighting AIDS with this software. OpenMRS has certainly shown to be up to the task at hand: it is currently tracking the medical conditions of over a million people in 12 countries.

Because of the exponential growth of users, this project is in urgent need of BI manpower. Julian and myself have both agreed to help out with strategical advice for the BI part of OpenMRS.

If you want to be part of the team, if you know a bit about the …

Ok, I'm a little travelled out with recent trips to around the US visiting customers, the Gartner conference and a trip to Europe for our developer meeting in Germany. So I'm glad that the upcoming Zend PHP conference (Oct 8-11) is in the bay area. I've been to this conference the last few years and it's a good one. Not as large as the MySQL conference, but if you're into PHP, it's got all the technical meat you could want, and then some. I expect the Zend execs (Harold Goldberg, Andi Guttmans and Mark DeVisser) will kick things off with... READ MORE

For those of you who enjoy running exotic operating systems: I just stumbled over a port of MySQL 5.0.45 for OS/2 and eComStation. Thanks a lot to Paul Smedley for maintaining this version! He also maintains a large number of other Unix applications that he ported over to OS/2 - very impressive.

Data warehouse administrators often want to give different users access to different subsets of the data. The OLAP model is a powerful paradigm for exploring data, and this paradigm also allows complex access-control rules to be expressed easily.

Mondrian already implements a rich set of access-control primitives (see mondrian schema guide), but we are considering some features to make mondrian more expressive in future releases.

Introduction: Access control in mondrian-2.4

In the current version of mondrian, roles are defined by elements in the mondrian schema file. A role can have access granted, or denied, for cubes, hierarchies, and members of hierarchies.

The type of access granted to an object is inherited by its children. For example, if you deny access to a schema, then access to cubes in …

Earlier this month (on the 4th, to be exact), OmniTI celebrated its 10th birthday. From humble beginnings in Theo's basement to a company of almost 50 employees, things have certainly changed. We now have an entire division devoted to email (Message Systems), a new office opening in New York, and a strong reputation that we all cherish. I haven't been here since the beginning, but I'm very proud to be a part of this team.

On his blog, Theo shares his thoughts on the occasion:

OmniTI is my other child, and the stresses and accommodations that I and everyone close to me have shouldered for …

This year, it seesm that whenever I go out for significant travel, the following things will break on my trip:

• a laptop power supply
• a disk

At least this time the disk is part of a RAID1 array.

Oh, and for some reason my mythbackend stopped doing anything a few days ago…. and I wasn’t checking it. grr… annoying. At least there’s not much on TV.
