		<description><![CDATA[Seen on EDS blogs: Data Management for SOA.
They wrote somewhere: &#8216;&#8230; Jill Dyche asserts that &#8220;SOA Starts with Data&#8220;. She advocates creating data services-creating data hubs as services that manage and provide access to master data. Starting with data services has an appeal to IT organizations that feel the need to adopt SOA &#8230;&#8217;
This sounds [...]]]></description>

		<description><![CDATA[Seen this interesting post seen on InfoQ, also relayed on Nati Shalom&#8217;s blog (Gigaspaces).
This raises some comments:

No discussion there is a need for in-memory databases.

RAM and network evolutions are changing the database space. And maybe the impact of network evolution is even more important than the RAM.

RAM disks exist for a long time in OS.
USB keys [...]]]></description>

		<description><![CDATA[First article about query optimizers: http://www.databasecolumn.com/2008/06/designing-systems-for-the-grid.html. I hope the following articles will give us much more information! That optimization problem is really interesting. We know it is a NP-complete king of problem. And it is even more interesting when dealing with multiple data sources. That&#8217;s one of the challenges of a modern Data Services Platform.

		<description><![CDATA[Seen on the ADO.Net blog this series of articles about the tooling for EDM. I especially like the fact the tools are available as wizards within Visual Studio but also as command-line scripts and APIs. That&#8217;s pretty cool, convenient and complete.

		<description><![CDATA[Interesting blog from Avi Bryant about Gemstone, Smalltalk and Ruby (Project MagLev).
For sure, dynamic languages are the best solution for persistence. It seems Smalltalk still rocks. Interesting to see that Ruby-Smalltalk coexistence in the same JVM. I really would like to see something like that on Groovy.
