Schema flexibility and XML data management
Conor O’Mahony, marketing manager for IBM’s DB2 pureXML talks a lot about one of my favorite hobbyhorses — schema flexibility — as a reason to use an XML data model. In a number of industries he sees use cases based around ongoing change in the information being managed:
- Tax authorities change their rules and forms every year, but don’t want to do total rewrites of their electronic submission and processing software.
- The financial services industry keeps inventing new products, which don’t just have different terms and conditions, but may also have different kinds of terms and conditions.
- The same, to some extent, goes for the travel industry, which also keeps adding different and different kinds of destinations.
- The energy industry keeps adding new kinds of highly complex equipment it has to manage.
Conor also thinks market evidence shows that XML’s schema flexibility is important for data interchange. Read more

Vertical market XML standards
Tracking the alphabet soup of vertical market XML standards is hard. So as a starting point, I’m splitting a list I got from IBM into a standalone post.
Among the most important or successful IBM pureXML-supported standards, in terms of downloads and other evidence of customer interest, are: Read more

Overview of IBM DB2 pureXML
On August 29, I had a great call with IBM about DB2 pureXML (most of the IBM side of the talking was done by Conor O’Mahony and Qi Jin). I’m finally getting around to writing it up now. (The world of tabular data warehousing has kept me just a wee bit busy …)
As I write it, I see there are a considerable number of holes, but that’s the way it seems to go when researching XML storage. I’m also writing up a September call from which I finally figured out (I think) the essence of how MarkLogic Server works – but only after five months of trying. It turns out that MarkLogic works rather differently from DB2 pureXML. Not coincidentally, IBM and Mark Logic focus on rather different use cases for native XML storage.
What I understand so far about the basic DB2 pureXML architecture goes like this: Read more
