    <p>I consider your approach to be the best overall. This comes after having tested with a number of different approaches myself.</p> <p>I see a number of huge benefits in your current approach, namely:</p> <ol> <li>Easily <strong>readable and understandable</strong> by anyone (in my experience, medium-level programmers often underestimate this and usually prefer going with fancy-patterns which, in the end are not readable at all for the vast majority of programmers who do not know that specific pattern)</li> <li>All the <strong>information is in one single place</strong>. As Andreas_D pointed out, hunting around files or classes is not a good option for someone that needs to fix a bug while you are on holiday!</li> <li>Easily <strong>maintainable</strong>: I could "F3" (if you are Eclipse-ing) on the method and add a new content type in seconds without any worries of introducing bugs!</li> </ol> <p>I can suggest a few things anyway:</p> <ol> <li>This method is very general purpose: Why should it be private?! This is a <strong>public method</strong> of some utility/helper class! Moreover it should be a <strong>static method</strong>!! You don't need anything from the Object itself to perform your job!</li> <li>You could use <strong>indenting</strong> to make things prettier and compact. I know that indenting is some kind of religion for the most of us, but I think it should not be a strict rule; it should be properly used to make our code more <strong>readable and compact</strong>. If this would be a config file you would probably have something like:</li> </ol> <blockquote> <pre><code>pdf=application/pdf doc=application/msword </code></pre> </blockquote> <p>You could have a very similar result with:</p> <pre><code> public static String getMimeType(String fileName){ if(fileName == null) return ""; if(fileName.endsWith(".pdf")) return "application/pdf"; if(fileName.endsWith(".doc")) return "application/msword"; if(fileName.endsWith(".xls")) return "application/vnd.ms-excel"; return "txt/plain"; } </code></pre> <p>This is also what a lot of the Map based implementations look like.</p>

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.
