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 the king's surprise at the noise made by the captain Cook's watch.
Text on source
While E-Tee was conversing on religious matters, king Aheatua was playing with Captain Cook's watch. After curiously examining the motion of so many wheels, that seemed to move as it were spontaneously, and shewing his astonishment at the noise it made, which he could not express otherwise than by saying it "spoke" (parou), he returned it, and asked what it was good for.
