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 way in which silence is maintained at their first meeting with the king: "mamoò" is translated as "be silent" and the king's attendants use strokes of a stick to ensure that the command is obeyed.
Text on source
During this conference the croud, amounting at least to five hundred persons, was so excessively noisy, that it was impossible at times to distinguish a word; and on those occasions some of the king's attendants with a Stentor's voice called out mamoò! (be silent), and enforced his command by dealing out hearty blows with a long stick.
