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.
Georg Forster describes a heiva, or dance, performed by a group of natives visting the Resolution.
Text on source
Some of them being in remarkable good spirits, gave us a heiva, or dance, on the quarter-deck. They placed themselves in a row, and parted with their shaggy upper garments: one of them sung some words in a rude manner, and all the rest accompanied the gestures he made alternately extending their arms, and stamping with their feet in a violent and almost frantic manner. The last words which we might suppose the burden of the song, or a chorus, they all repeated together; and we could easily distinguish some sort of metre in them, but were not sure they had rhimes. The music was extremely rough, and of no great extent in these kinds of songs. In the evening they all went off again, and returned to the upper part of the sound from whence they came.
