Body
Let's take that bit by bit. <code>data</code> is the iterator showing where to start. It's an array, but in C and C++ arrays decay to pointers on any provocation, so it's used as a pointer. Start taking in data from <code>data</code> on, and continue until the end iterator. The end iterator is a certain amount past the start iterator, so it can be expressed as <code>data + <something></code>, where <code><something></code> is the length. The start iterator is an <code>int []</code> that is treated as an <code>int *</code>, so we want to find the length in <code>int</code>s. (In C and C++, pointers increment by the length of the pointed-to type.) Therefore, <code>sizeof(data) / sizeof(int)</code> should be the length of the array. <code>sizeof(data)</code> is the total size of the array in bytes. (This is one of the differences between arrays and pointers: arrays have a defined size, while pointers point to what might be the start of an array of unknown size.) <code>sizeof(int)</code> is the total size of an int in bytes, and so the quotient is the total size of <code>array</code> in <code>int</code>s. We want the size of <code>array</code> in <code>int</code>s because <code>array</code> decays into an <code>int *</code>, and so <code>data + x</code> points to the memory location x <code>int</code>s past <code>data</code>. From a beginning and a total size, we find the end of <code>data</code>, and so we copy everything in <code>data</code> from the beginning to the end.

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.
