    <p>Recently, for a data structures class, I was asked the question of how a lazy deletion (that is, a deletion that first marks the items needed to be deleted, and then at some time later deletes all the marked items) would be advantageous/disadvantageous to an array, linked list, or binary tree. Here is what I have come up with:</p> <ul> <li>This would help arrays because you would save the time that is taken to shift the array every time an index is deleted although in algorithms that need to traverse the array, there could be inefficiencies.</li> <li>This would not help linked lists because you need to traverse O(n) to mark an item to be deleted anyways. </li> <li>I'm not entirely sure about binary trees, but if it were a linked list implementation of one I would imagine it is like the linked list?</li> </ul>

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.
