Hi folks

I am trying to come up with a good design for a movie database.
The information I want to store about each movie is:
Title, Actors, Genres, Writers, Director(s), Country, Year, Running Time, Rating, Keyword

It must be possible to search by any of these, and any combination of these.
I figured Actors, Writers and Director(s) are persons and can as such be stored as a separate "Person" db.
Should I also detach for example genre or country or keywords as separate tables? I know one movie can have several genres and vice versa.
And if so, how should I link for instance genres to the movie table?

I am quite a newbie in databases, so please forgive my infantile questions.
I just want to have a robust and strong database that can handle multiple searches on any column.

Thanks.

Do you know what a many-to-many relationship is? And, how it is implemented in a relational database?
