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.
The Moroccan soldiers praise God loudly with traditional Islamic phrases.

وحين ابصرهم اصحاب جودر يتهيئون للهروب وعرفوا ما حاق بهم من الرعب والاضطراب وقفوا وصاحوا ورفعوا عقيرتهم بلا اله الّا الله اشكروا الله الدائم الدوم [ص. ١٤٨]
English translation
When the Moroccans saw them [the Songhay] had decided to flee, and when they realized the scope of the trouble and agitation
that they had brought, they stopped and let loose resounding cries, saying: "There is no god but God, praise God, the Eternal, the
Immutable!"
