New tricks and old tools- May 16, 2008 Kim Cameron follows up on Clayton Donley's post with some thoughts of his own. And ends by quoting Clayton:"The real solution here is a combination of virtualization with more standardized publishsubscribe for delivery of changes. This gets us away from this ad-hoc change discovery that makes meta-directories miserable, while ensuring that the data gets where it needs to go for transactions within an application."and adding: " As soon as applications understand they are PART OF a wider...http://vquill.com/2008/05/new-tricks-and-old-tools.html optimization and expense- May 12, 2008 Neil Macehiter comments on the last post:But the issue is not with the language you use to perform the query: it's where the data is located. If you have data in separate physical databases then it's necessary to pull the data from the separate sources and join them locally.

He says:"Sometimes an application needs to do complex searches involving information 'mastered' in multiple locations. Ill make up a very simple 'two location' example to demonstrate the issue: 'What purchases of computers were made by employees who have been at the company for less than two years' Here we have to query...http://vquill.com/2008/05/getting-more-violent-all-time.html The COBOLization of LDAP- May 10, 2008 In a panel discussion at the recent European Identity Conference I referred to LDAP (Lightweight Directory Access Protocol) as "The COBOL of Identity." It came amidst a discussion of future identity-sharing protocols and was intended as 1) a cheap laugh; and 2) as a short, memorable way of saying that LDAP would always be with us.I mentioned it again in a newsletter about the show ("Building an Identity Bus, Part 2") which has now been misread by a couple of people, so let me set the record...http://vquill.com/2008/05/cobolization-of-ldap.html |
