Would you please give me a tip about relations in OrientDB and ObjectApi?
Suppose that there are 2 classes
Public class Person {
Private String name;
...
}
Public class Group {
@ManyToMany
Private Set <Person> members;
...
}
And in DB an object 'myGroup' with linkset to persons_1, person_2
Now we want to remove person_1.
How to prevent situation where members include link to deleted object?
Does OrientDB have a built-in mechanism to remove link from members in this
situation?
Is it possible to force OrientDB to return an exception during attempt to
remove person_1?
What is the best way to find all group of person_2? Do I need to use sth
like "select from group where ..." or is another way?
Above is easy but we can have A with links to B, and B links to C etc. It's
easy to move from A to C but what the best way the search objects in the
opposite direction?
