    <p>There are a few big benefits to using a framework over homegrown/handwritten code:</p> <ul> <li><p><strong>Abstractions</strong>. I'm sure you're very proud of the fact that you've slung enough JS to be able to write animations from scratch. You should be! However, abstracting common functionality away from yourself is actually very liberating. You just call the method and know the innards will be executed, and executed well. Even if you're very fast at writing the low-level stuff yourself, that's still time you've spent on that instead of solving today's problems.</p></li> <li><p><strong>Common language</strong>. Using a common framework is like speaking a common language. You can collaborate with other developers very easily, and each can pick up where others left off without friction. (Compared to stepping into an application which uses a homegrown library for the things jQuery can do.)</p></li> <li><p><strong>Experts</strong>. The people working on jQuery are JavaScript <em>gods</em>. I am really, really good at JavaScript, and you probably are too, but there's a big difference between normal good and jQuery good. A team of insanely good people are constantly poring over a small set of common functionality - tuning it, tweaking it, enhancing it to make it the best it can possibly be. That represents a huge number of man-hours a single person like you or me simply cannot reproduce, no matter how good we are. And if you <em>are</em> as good as the jQuery guys, you can only benefit by combining your talent with theirs and contributing to the jQuery codebase. It's a melting pot of insane talent.</p></li> </ul>

    1. COI'm not sure I agree with the "common language" part. JavaScript can just as easily be a common language as jQuery (and at the moment is probably moreso, though jQuery is certainly picking up in popularity).

    2. CO@Daniel yes, but the question is asking why use jQuery instead of manually implementing the things jQuery does. The "common language" I am referring to is stepping into an app that uses jQuery vs stepping into one that uses something homegrown.

    3. COAh, so you mean a common language for the abstraction you were talking about in the first point. I agree with that.

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.
