Some stuff that’s always on my mind
I have a LOT of partially-written blog posts, but am struggling to get any of them finished (obviously). Much of the problem is that they have so many dependencies on each other. Clearly, then, I...

MongoDB 3.4 and “multimodel” query
“Multimodel” database management is a hot new concept these days, notwithstanding that it’s been around since at least the 1990s. My clients at MongoDB of course had to join the train as well, but...
View ArticleNotes on the transition to the cloud
1. The cloud is super-hot. Duh. And so, like any hot buzzword, “cloud” means different things to different marketers. Four of the biggest things that have been called “cloud” are: The Amazon cloud,...
View ArticleOracle as the new IBM — has a long decline started?
When I find myself making the same observation fairly frequently, that’s a good impetus to write a post based on it. And so this post is based on the thought that there are many analogies between:...

View ArticleMulti-model database managers

7-10 years ago, I repeatedly argued the viewpoints: Relational DBMS were the right choice in most cases. Multiple kinds of relational DBMS were needed, optimized for different kinds of use case. There...
View ArticleUsing multiple data stores
I’m commonly asked to assess vendor claims of the kind: “Our system lets you do multiple kinds of processing against one database.” “Otherwise you’d need two or more data managers to get the job done,...
View ArticleDBMS2 revisited
The name of this blog comes from an August, 2005 column. 8 1/2 years later, that analysis holds up pretty well. Indeed, I’d keep the first two precepts exactly as I proposed back then: Task-appropriate...

View ArticleDatabase diversity revisited
From time to time, I try to step back and build a little taxonomy for the variety in database technology. One effort was 4 1/2 years ago, in a pre-planned exchange with Mike Stonebraker (his side,...

View ArticleMany kinds of memory-centric data management
I’m frequently asked to generalize in some way about in-memory or memory-centric data management. I can start: The desire for human real-time interactive response naturally leads to keeping data in...
