Wez Furlong asks today for any kind of feedback he can get from readers about the Service Data Objects functionality in PHP, specifically questions you might have about them.

One of the things that was apparent was that this SDO stuff has quite a high barrier to entry--too many three letter acronyms for starters, and its origins in the C++ and Java world don't help make it very accessible to the typical PHP developer.

Wez references two articles over on the Zend Developer Zone as great places to get started. He also mentions giving some feedback to the IBM folks about the SDO extension:

If you've wondered what this SDO stuff is all about, please read through those articles. After having done that, if theres something you're not clear on, or if everything is clear, or if you have some other thoughts on the matter, then please take a moment to send your feedback to Graham Charters (you'll find his email address on the top of the articles).
