Martin Ouellet Notes: October 2011
http://martin-ouellet.blogspot.com/2011_10_01_archive.html
Anything but a. blog! Tuesday, October 04, 2011. A Source-to-Target self-documentation system. In the BI world, the corporate Data warehouse platform gets often overly complex quite rapidly. The number of source components increases rapidly to reach nearly thousand of entities:. Consider 10-15 different OLTP’s sources each having roughly 10-20 entities worth of interest (tables and views). Consider also the few File-based sources each accompanied with one or more feed entities. Now consider that each one.

Where some points and issues are discussed. Open Points and Discussion. 8594;Business Key inconsistencies. Among all OLTPs used as source, it is very unlikely that they will all share exact same Key(s) to represent same business entity! If we are lucky, keys will vary in format only, but more frequently, keys can be totally different.

Anything but a. blog! Sunday, July 27, 2014. We have been deploying a database service at work which is based on PostgreSQL.

This global setting defines amount of memory shared across all. Is definitely too low. Updating this g...

Martin Ouellet Notes: August 2013
http://martin-ouellet.blogspot.com/2013_08_01_archive.html
Anything but a. blog! Tuesday, August 06, 2013. BI “ideal” platform. In dealing with BI projects, you are much more likely to work under the constraint of an existing platform than building one from scratch. This means having to deal with platform idiosyncrasies, sub-optimal architecture, complex and large data models, tangled loading dependencies and scheduling, confusion or mix of approaches and architecture, etc. Visibility: any layer can only depend on the immediate lower (preceding) layer. Data depe...
