Sometimes you inherit a large database from somebody else, and you simply don't see how it comes together. (OK, be honest. Sometimes you create a large database and still don't understand how it's put together.) While FileMaker's point-and-click interface makes it easy to build databases, teasing things out later is a different story. You can look at a script, field, layout, table occurrence, or even an entire table in FileMaker Pro, and have no idea whether the database actually uses or needs it.
If you've shelled out for FileMaker Pro Advanced, however, you've got help. Its built-in internal analysis tool, the Database Design Report (affectionately called DDR), gives you an overview of your database, where you can easily see how database items are connected and other details, all in one place.
