				    Space4J is a <B>simple database system</B> that will let you work with <I>Java Collections</I> in memory.
                    Instead of having to perform a <I>SQL SELECT</I> to fetch a <I>User</I> from a database table, you can just 
                    access the <I>users</I> map (<I>java.util.Map</I>) and call <I>users.get(id)</I>. With Space4J, all your data
                    is kept in memory inside the JVM. There is no need for an extra database application, a socket connection, a
                    JDBC driver, a SQL statement or any kind of ORM tool. Your data is just there, in memory, inside the JVM,
                    inside objects, inside Java maps. What can be faster and more straightforward than that?</DIV></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/0C325D6B-9B65-49AB-9861-47AD4619E100/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
