    <p>I seem to be a little bit confused when comparing Clojure's <strong>core.async</strong> to the so called <strong>Reactive Extensions</strong> (Rx) and <strong>FRP</strong> in general. They seem to tackle similar problem of async-hronicity, so I wonder what are the principal differences and in what cases is one preferred over the other. Can someone please explain?</p> <p>EDIT: To encourage more in-depth answers I want to make the question more specific:</p> <ol> <li><p>Core.async allows me to write synchronous-looking code. However as I understand it FRP only needs one level of nested callbacks (all the function that handle logic are passed as arguments to FRP API). This seems that both approaches make the callback <em>pyramids</em> unnecessary. It is true that in JS I have to write <code>function() {...}</code> many times, but the main problem, the <em>nested</em> callbacks, is gone in FRP also. Do I get it right?</p></li> <li><p>"<strong>FRP</strong> complects the communication of messages with flow of control" Can you (someone) please give a more specific explanation?</p></li> <li><p>Can't I pass around FRP's observable endpoints the same way as i pass channels?</p></li> </ol> <p>In general I understand where both approaches historically come from and I have tried few tutorials in both of them. However I seem to be "paralyzed" by the non-obviousness of differences. Is there some <strong>example of a code that would be hard to write in one of these and easy using the other</strong>? And what is the architectural reason of that?</p>

    2. COThat's not quite true, as it is quite possible, and encouraged for things such as pub/sub, especially with a combineLatest when flattened.

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.
