    <p>It's an array of integers. It was created this way: No element is repeated. Every time an element is added, its number is the next available integer, from 0 onwards. This way, if you add 6 elements in a row, they will be 0, 1, 2, 3, 4, 5, in that order. If you delete an element, the array shrinks, and a 'hole' is left between two of the elements, they are no longer consecutive because of that gap: 0, 1, 3, 4, 5. Then comes the problem: if you add a new element, it gets added to the end, but has the next available integer. So, the array is now 0, 1, 3, 4, 5, 2. It needs to be sorted, so the 2 can occupy its place between the 1 and the 3. What is the best way to do it? I have thought of several methods. The list is nearly ordered, and it has the property that, when it is ordered, every element is equal to or greater than its index in the array. I am currently doing a bubble sort (don't laugh), i think quick sort is overkill, i dont want to go recursive or use temporary arrays, and i dont want to change the add-element method (which adds the element at the end), so it must be sorted immediately after adding an element (so only the last element is out of place)</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.
