Basic Explaination of OO in Ada

[richard.charts@gmail.com]

I'm new to Ada, having to learn it for work, and I am beginning to
understand the language, I think.
However, coming from C (and family) and Java and other "modern"
languages, I can't seem to wrap my head around Ada's OO methods.  Is it
that there is simply nothing like a class in C++ or Java?

As a learning exercise, I'm trying to convert a simple Python program
to Ada.
The basics of the program were that it took in data about a Person
object(or Student or Advisor) and stored it into array for
manipulation.
At first, I kept trying to convert almost line for line to Ada.  But I
couldn't build the classes in the same way.
Is the correct way to think in Ada, that in a package, there is some
record "object" and also a number of subprograms that can interact
with/on that record?


Thanks.
