What does a data analyst do? do you do data analysis?

Yes, and there are some things that OO language is not well suited to express. Complex interrelationships in shared data is one such thing.

Do a google search on "generalization specialization relational modeling". You'll find several interesting articles on the subject. Most of what you will learn will be overkill for the problem you stated in the OP. But if you are interested in general principles, you'll learn some interesting things from the articles.
