I made some reading and after getting familiar wit normalization rulez I decided to divide this in four tables:

1st table "Basic info"with columns: movieID,titleID, directorID, yearID

2nd table:"Artists ID" with colums: movieID, titleID, artist1_ID, artist2_ID,artist3_ID,artist4_ID
Click Here

3rd table "CategoryID" with columns: movieID, titleID, category1_ID, category2_ID, category3_ID, moodID
Click Here

4th table "DescriptionID" with columns: movieID, titleID, trailerID, descriptionID

Im having problem with creation relations. I know it should be one-to-many relation but I dont know how to draw it in diagram. Can anybody help me with this please ? Also are tables above look alright ?

Thanks in advance

None of your images show a diagram, just a table layout. It's hard to guess how far you want to take this, but I'd suggest never to create columns named "artist1_ID, artist2_ID, artist3_ID, artist4_ID". This indicates that you need an intermediate table, because what do you do when you need more than four artists.

I'd suggest you start by describing what entities you want to store, e.g. movies, genres, actors. Based on that my choice would be something like this:

------------  -------  -----------  --------------
Id (PK)       Id (PK)  Id (PK)      MovieId (FK)
Title         Name     Description  ActorId (FK)
GenreId (FK)

Trailers and directors can be solved just like MOVIES_ACTORS because you can have more of them for a single movie.

Thanks a lot of the quick review. It will help me a lot.

Why did you use 2 foreign keys in movies_actors table ?
