In some respect, it depends on your point of view. All of the
data structures quoted in the previous articles in the thread
are in fact collections with different access policies. Data bases
are also collections with different access policies (SQL being
by far the most popular one).
I normally think of a data structure as an abstract description
of a way to organize a collection, a collection as a concrete
example of a data structure with specific data that is in
memory, and a data base as something that is managed
by an external piece of software, called a 'data base
