But the story is not finished, Data Services are very trendy these days, so the whole blog and its content has been moved to www.dataservices-connection.com and I will now post new articles over there.

		<description><![CDATA[WSO2 recently introduce its new version of Data Services. The big new improvment is the ability to aggregate data from multiple databases.
See http://www.ebizq.net/news/10368.html and http://blogs.zdnet.com/Gardner/?p=2741.

		<description><![CDATA[Seen this article by Jean-Jacques Dubray on InfoQ, related to this other article by Arnon Rotem who explains why Database-as-a-Service (DBaaS) is a bad idea:

It circumvents the whole idea about &#8220;Services&#8221; - there&#8217;s no business logic
It makes for CRUD resources/services
It is exposing internal database structure or data rather than a thought-out contract
It encourages bypassing real services and [...]]]></description>
