I believe the Erlang community is not envious of Node.js as it does non-blocking I/O natively and has ways to scale deployments easily to more than one processor (something not even built-in in Node.js). More details at <a href="http://journal.dedasys.com/2010/04/29/erlang-vs-node-js" rel="noreferrer">http://journal.dedasys.com/2010/04/29/erlang-vs-node-js</a> and <a href="https://stackoverflow.com/questions/3011317/node-js-or-erlang">Node.js or Erlang</a> What about Haskell? Can Haskell provide some of the benefits of Node.js, namely a clean solution to avoid blocking I/O without having recourse to multi-thread programming? <hr> There are many things that are attractive with Node.js <ol> <li>Events: No thread manipulation, the programmer only provides callbacks (as in Snap framework)</li> <li>Callbacks are guaranteed to be run in a single thread: no race condition possible.</li> <li>Nice and simple UNIX-friendly API. Bonus: Excellent HTTP support. DNS also available.</li> <li>Every I/O is by default asynchronous. This makes it easier to avoid locks. However, too much CPU processing in a callback will impact other connections (in this case, the task should split into smaller sub-tasks and re-scheduled).</li> <li>Same language for client-side and server-side. (I don't see too much value in this one, however. jQuery and Node.js share the event programming model but the rest is very different. I just can't see how sharing code between server-side and client-side could be useful in practice.)</li> <li>All this packaged in a single product.</li> </ol>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
