Object database experts select the best patterns

Eric Lai emailed today to ask what I thought about the NoSQL folks, and especially whether I thought their ideas were useful for enterprises in general, as opposed to just Web 2.0 companies.

There has been some discussion in recent days regarding Object-Relational Mappers (ORMs), Drupal, and why the latter doesn't use the former. There are, actually, many reasons for that, and for why Drupal doesn't do more with the Active Record pattern.

The PostgreSQL Global Development Group has released version 8.4, continuing the rapid development of the world's most advanced open source database.

Sometimes people will just trust your instincts but other times they will challenge you. There are many outcomes of such challenges. You may fail to convince anybody of your instincts. But, there are times when the challenge will lead you to a better understanding of your intuition. And that is exactly how I arrived at a simple realization of how performance and scale balanced to build usable, high volume web sites and services.
