    <p>How well did you look into Doctrine? I am using Doctrine 1.2 for these kind of things. Quite easy to setup, allows you to start off with an existing schema. It automatically figures out the relations between tables that have foreign key constraints.</p> <p>It has extensive trigger and behaviour support, so the bonus points can be spent as well, and it has relational support as well, so your additional queries are not necessary. It has beautiful lazy loading, and it comes with a flexible query language (called DQL) that allows you to do almost exactly the same stuff that you can do in SQL in only a fraction of the effort.</p> <p>Your example will look like this:</p> <pre><code>/* To just find one user */ $user = Doctrine::getTable('User')-&gt;findOneById($id); /* Alternative - illustrating DQL */ $user = Doctrine_Query::create() -&gt;from('User u') -&gt;where('u.id = ?',array($id)) -&gt;fetchOne(); $user-&gt;name = 'John Woo'; $user-&gt;save(); </code></pre> <blockquote> <p>It must be able to work alongside the existing raw mysql_* queries. I have no idea how hydrating ORMs like Doctrine 2 or Propel behave when scripts are manually manipulating the data in the database behind their backs, but I assume it's not pretty.</p> </blockquote> <p>Well, that is technically impossible to auto-manage; a SQL database is simply not pushing back stuff to your ORM, so to update stuff that was changed in the background, you need to perform an additional query one way or the other. Fortunately, Doctrine makes this very easy for you:</p> <pre><code>/* @var User $user */ /* Change a user using some raw mysql queries in my spaghetti function */ $this-&gt;feedSpaghetti($user-&gt;id); /* Reload changes from database */ $user-&gt;refresh(); </code></pre>

    1. COBut what happens when some other part of the app, still using raw mysql_* calls, changes the data behind Doctrine's back? Or worse, when the schema changes underneath it's feet? Like I said, the app is 125K spaghetti code with a seriously denormalised database behind it. Assume the worst. Multiply by a factor 2. Can Doctrine handle that?

    2. CONot sure if you already read my update. You do need to refresh the record, but hey, due to the nature of SQL, it will be like that in any ORM. If you are afraid of a Doctrine record getting outdated, simply refresh it, and its field values will be re-acquired from the database.

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.
