Hm, that's not completely true... ;-)
The whole structure Masi mentioned will be deleted when the parent is
removed (1:n composition). But a person can have different employments
and thus different jobs (e.g. being the manager of a company by day and
working in a supermarket at night). A working structure could be:

company --[1:n]--> job --[1:n]--> job_person_rel <--[1:n]-- person

If the company is deleted, the job is removed as well. But the person
will stay untouched - only the information about the employment, the
relation on the table "job_person_rel" itself, will be removed.
