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 reunion with the Adventure.
Text on source
We conceived that they were signals made by Europeans, and probably by our friends in the Adventure; immediately and upon firing some four-pounders, had the pleasure of being answered out of the Ship Cove, opposite the island. Towards noon we could discern our old consort at anchor; and soon after were met by several of her officers, who brought us a present of fresh fish, and gave us an account of what had happened to them after our separation. In the afternoon it fell calm, so that we were obliged to be towed into the cove, where we anchored at seven in the evening. In the mean time Captain Furneaux came on board, and testified his satisfaction at rejoining us, by a salute of thirteen guns, which our people cheerfully returned.
