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.
On another of his excursions, George Forster describes the sound of birds and a loud noise he discovers coming from a hut in the forest. Here he saw women making cloth from mulberry bark.
Text on source
Whether it was owing to the early hour of our excursion, or to the beauty of the morning, our ear was saluted by the song of many small birds, which enlivened this delightful country. We had not walked far, when we heard a loud noise in the wood, which resembled the strokes of a carpenter's hammer. We followed the sound, and at last came to a small shed, where five or six women were sitting on both sides of a long square piece of timber, and beat the fibrous bark of the mulberry-tree here, in order to manufacture it into cloth.
