Like <code>NSDictionary</code> (<a href="/questions/tagged/nsdictionary" class="post-tag" title="show questions tagged 'nsdictionary'" rel="tag">nsdictionary</a>), it is a subclass of <code>NSObject</code> (<a href="/questions/tagged/nsobject" class="post-tag" title="show questions tagged 'nsobject'" rel="tag">nsobject</a>), that allows you to have a collection of objects, but instead of having them stored in an array retrievable by their index, they are stored as a key-value pair. Each object stored in an <code>NSDictionary</code> can be retrieved by a unique key assigned to it. Keys have to be unique and can be any object as long as they adopt the <code>NSCopying</code> protocol – they are usually an instance of <code>NSString</code> (<a href="/questions/tagged/nsstring" class="post-tag" title="show questions tagged 'nsstring'" rel="tag">nsstring</a>). Neither a key nor the object paired with it can be nil, however, you may use <code>NSNull</code> for storing null objects. If two objects are stored with the same key, the first one is released, and the last one is stored. When using key-value coding, the key must be a string. When using key-object coding, the key is copied using <code>copyWithZone:</code> and it must conform to the <code>NSCopying</code> protocol. This object is retained, rather than copy. <code>NSMutableDictionary</code> gives you the ability to modify this set of key-object paired collection without having to empty it and refill it again as a whole set. The following methods are for this purpose: Adding Entries to a Mutable Dictionary <pre><code>– setObject:forKey: – setValue:forKey: – addEntriesFromDictionary: – setDictionary: </code></pre> Removing Entries From a Mutable Dictionary <pre><code>– removeObjectForKey: – removeAllObjects – removeObjectsForKeys: </code></pre> <h3>Resources:</h3> <ul> <li><a href="http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSMutableDictionary_Class/Reference/Reference.html" rel="nofollow">NSMutableDictionary Class Reference</a>.</li> </ul>

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.
