Please note that all relationships with this element, and all its children will be deleted as well.
What does this mean?
Parent, Children and Cascade deletions
"Children" elements are elements that directly depend on another object (the "parent").
They only have sense in a certain context, and if the context to which they belong is removed, to mantain data meaning and integrity the application provides also the removal of them (now become "orphans").
Example
Take the case of a Travel and of the Events occurred during it.
In this example, deleting a Travel will leave all of its Events meaningless since, taken alone, they would have no context in which to place themselves, nor a way to reach them.
Consequently, the removal of a Travel also causes the elimination - cascading - of all Events that occurred in that Trip.
Important
Note that this operation is not limited to one level of relationship, but proceeds with children of deleted children and so on, until the entire database is freed from unnecessary data.
This lets the user remove all data about a Travel by simply deleting that Travel.
121. A kind of musical instrument of New Caledonia
New Caledonia (Nuova Caledonia - Grande Terre)
Title
A kind of musical instrument of New Caledonia
Short description
Georg Forster describes a kind of musical instrument that the natives brought with them to sell.
Text on source
They brought a musical instrument, a kind of whistle, for sale this day. It was a little polished piece of brown wood, about two inches long, shaped like a bell, though apparently solid, with a rope fixed at the small end. Two holes were made in it near the base, and another near the insertion of the rope, all which had some communication with each other, and by blowing in the uppermost, a shrill sound, like whistling, was formed at the other. Besides this, we never observed any instrument among them which had the least relation to music.
