I harp on Design Goal 6 in the XML 1.0 Standard , "XML documents should be human-legible and reasonably clear". In Kontrawize, the response is XML editors help meet this design goal. "There are plenty of good XML-aware editors around, some of which are free." While true, I think this …

The XML folks seem to have a number of points:

• Ant already works. Complexity be damned.
• XML is fine for everything that's not Java. Except SQL. And CSS.
• Ant is "already" part of the technology stack, and it uses XML. Anything better isn't already there.
• Everyone already knows XML. They …

The points are serious issues. However, the best summary comes from Karl Guertin: "My explanation is that Duck Typing is like Ethernet, in theory it will break, but in practice it works pretty well."

There were three questions which raised four issues. The questions included the seemingly incomplete OO implementation …

This is an important topic. I've blogged on the layers issue before ("Layers, Interfaces and Mutabilty "), and this AJAX issue is a great additional point.

With depressing regularity I also hear the complementary "stored procedure" question. This question takes a number of different forms, but they all mean the same …

I'm very excited to be giving a presentation at PyCon '07. A 30-minute slot is tough because the Star Schema can be confusing. The coding is pretty transparent (IMO), but the background for why I had to do this and places where it can be used are more interesting than …

In the CW article, pseudonymous Mathias Thurman describes a demonstration of Microsoft's Rights Management Services product. The audience of executives identify a number of "Suppose..." scenarios, which the author dismisses as merely research subjects, concluding that "...the goal of this proof of concept was to introduce a group of executives …

Here's the full, minimally-edited question:

"We are having a debate about the basic way the UI, Business Logic, and Data Access layers communicate.

My experience has been that the UI talks to the BizLogic, and the BizLogic maps between itself and the Data Access layer.. like this:

::

UI -> BizLogic -> Data …

First, see "OSCON - Open Data " by Tim Bray, then see "Set My Data Free " in Kontrawize.

Here are some quotes "At the end of the day, information outlives software and transcends software and is more valuable than software." "Data matters. It shouldn't be an afterthought. It will outlive your applications …

I do a fair amount of manual refactoring. I've used WebSphere Studio (Eclipse) to do some automated refactoring, so I have some experience in using IDE's which exploit Java's static type-checking.

However, the question of type checking in a dynamic language is interesting. I don't use a sophisticated IDE for …

In one case, the prospect had 7 interlocked databases, and wanted to do a technology upgrade. In other cases, the numbers was larger (up to 30, I think) but the problem was the same.

Essentially they said "It's taking us forever to rework this design. What should we do that …
