    <p>It is important that you have stated the purpose of your software will be to answer various questions about the book, including what characters appear on a given page.</p> <p>This tells us two things:</p> <ol> <li>You are seeking to model the physical layout of a particular edition of a book (since other wise the example question above would make no sense).</li> <li><p>Your design is going to be heavily influenced by the scope of the questions that need to be answered, as this will determine whether your system will:</p> <ul> <li>use data structures to pre-cache meta-data that will be required as answers (e.g. explicitly store a list of pages a character appears on),</li> <li>store the "raw data" (e.g. as a tree of novel > chapters > pages > text) which is then processed to answer a given question,</li> <li>some combination of both</li> </ul></li> </ol> <p>I suspect that a combination is likely to be right in your case, so your "raw data" will be represented in similar fashion to the first approach you mention:</p> <blockquote> <p>Make everything (Novel, Chapter, Page, Character) an object, and each of these objects has lists of references to other objects they contain / relate to"</p> </blockquote> <p>except that instances of <code>Page</code> would reference instances of <code>Text</code>, rather than <code>Character</code> which instead would become a meta-data class.</p> <p>Meta-data could be pre-cached, or generated on demand by trawling the raw data.</p> <p>Either way, you'll want to normalize your data model, </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.
