    1. COOff-topic, but you should get out of the habit of using `new` when you don't need it, and of using dumb pointers when you do need it. Otherwise, you'll end up spending your life debugging memory leaks like the one in your example, rather than writing interesting code.

    2. CO@MikeSeymour I am here to learn. If I would forego using new, could you please provide some alternative way of doing it?

    3. COIn this case, a simple automatic local variable: `people<name<string>> aPerson;` When you do need dynamic allocation (because the object has to outlive the function that creates it), you should learn about [RAII](http://en.wikipedia.org/wiki/Resource_Acquisition_Is_Initialization) and, in particular, *smart pointers*.

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.
