A handy list of rules One of the major discussion points at Bloor Research's recent conference on "Data Warehousing: the rise of the appliance" was a discussion of the rules (though they might equally be regarded as reference points rather than rules) that might apply to data warehouse appliances as opposed to enterprise data warehouses.â¦

Continuing on from the first part of the series looking at the use of Adapter objects, DevShed has posted part two today - using the Adapter objects along with Directory Iterators to integrate with a MySQL database.   Provided that you understand the basic concepts of the adapter pattern, in this final tutorial, I'll show you how to use it in conjunction with the "DirectoryIterator" class, bundled with PHP 5, and with a couple of MySQL wrappers as well.   They jump right in (as was said, assuming you read the previous article) to using the directory iterators and the adapters together to make a class that gets information about the files in a directory. They take this and show a sample use that's then transformed into a class capable of using the same logic on MySQL results.

A look at Oracle, ParAccel and Calpont A lot has been happening on the data warehousing front lately. Earlier this summer, Oracle announced its Information Appliance initiative and, in particular, a partnership with PANTA Systems. Then, more recently, ParAccel has announced a product re-positioning, Calpont is finally talking about its entry into the market, and both DATAllegro and Netezza have announced new product releases. In this article I am going to discuss Oracle, ParAccel and Calpont (for reasons which will become obvious) while in the second part I will direct my attention towards DATAllegro and Netezza.â¦

Michael Kimsal has come up with the start of a series to introduce PHP developers to the world of Grails (the Java framework).   The comparisons I plan to make will be mostly to PHP, cause that's what I'm most familiar with, though there may be some other comparisons from time to time.  This is a work in progress, but I'd be very interested in feedback from anyone out there interested in this aea - Grails, Groovy, PHP, why another language/platform/framework, etc.   The first two installments have been posted - part one and part two - with an introduction to what Grails is and a brief dip into some "Hello world" sort of code to give you an idea of the structure.

Stuart Herbert has posted a new book review of a new offering from Packt Publishing - "Learning PHP Data Objects" (by Dennis Popel).    The folks at Packt Publishing sent me a copy of Dennis Popel's "Learning PHP Data Objects" to review. I'd never heard of Packt before, and was intrigued.   He includes a high-level overview of what the book contains, but notes that he couldn't get a hold of the code examples mentioned in the book (no CD and couldn't find it on their site). Overall, he found it a good book - it's a good primer to PDO in PHP, but you'll need to know SQL beforehand to work with it. He suggests that it's more of a one or two time read, though - not much in the way of a reference to come back to.
