Noun categorization

I want to store nouns in a database, but the categorization is not all that clear to me.
What I mean is that it seems that many words can be applied to different categories.

Categories identified:

• Common
• Proper
• Concrete
• Abstract
• Collective
• Countable / Uncountable (mass)

It would seem that the only clear distinctions are:

• Proper
• Concrete vs Abstract
• Countable vs Uncountable

It would seem that:

• Common nouns can be either concrete or abstract, countable or uncountable.
• Collective nouns can be common (and all other categories mentioned in previous point)

I’m a bit fuzzy on what the purpose of this categorisation, so could you confirm that this is correct?
