				Memory Analyzer has a built-in object query language
				(OQL) that allows to query the heap dump with custom
				SQL-like queries. Just think of classes as tables,
				objects as rows, and fields as columns. The basic syntax
				is this:</p>
				<codeblock>SELECT * FROM [ INSTANCEOF ]	&lt;class_name&gt; [ WHERE &lt;filter-expression&gt;]
				</codeblock>
