			<content:encoded><![CDATA[<p>Open source is a great idea. Find a widget that does what you want, make a contribution to the authors, drop it into your web-site and go forth. There are some great widgets and systems out there. Without Apache, mySQL, and hundreds of other packages the internet and systems development would be a more sterile environment.</p>
<p>But there are also all the other open source developments. Great ideas with some great programming, but could have done with a once over with someone who is experienced in the areas that the initiator is not expert in. On the one hand at least I have a starting point, on the other hand it puts some butter on earning my daily bread.</p>
<p>I was trying to think of how to compose an organised thread on this topic when I saw this excellent representation <img src="http://www.codeproject.com/KB/database/Visual_SQL_Joins/Visual_SQL_JOINS_orig.jpg" title="SQL Joins" width="450px" height="300px">. </p>
<p>The number one reason people ask me to look at their open source web-site is that they are starting to generate traffic and the site just gets slower and slower. The reason? SELECT <em>alist</em> FROM <em>tablea</em>, <em>tableb</em> WHERE <em>tablea.id</em> = <em>tableb.id</em>;.  Learn how to use joins properly and we can all get to do more interesting and productive work.</p>
<p>Thanks.</p>
