[Tutor] Sort of database & "family tree" question

[Timo]

Hello,

I'm writing an application that stores people with some info. I'm doing 
this with ConfigParser and it works, but currently (for testing), there 
are only 10 persons in it. What if I add, let's say, about 500-600 or 
even more? Is this still a good choice?

So my entry's look like this (more or less ;)):
[person1]
firstName = foo
lastName = bar
father = person2
mother = person3


Now, I want to make a family tree out of this, something that looks like 
the following scheme (hope the formating will be kept):

For person "foo bar", on his father-side, and mother-side the same.

                                 | father
                 | father--<
                 |               | mother
person2--<
                 |               | father
                 | mother--<
                                 | mother

Greets,
Timo
