Re: Normalization question

Thanks for you responses! This list has proven to be for useful to pick pick the brains of other DBA's. I think we are probably going to go the route of splitting the different pieces of data into seperate columns, while keeping the original product_id, since we have a lot of third party applicat

Hi! I don't understand problem. Car can belong to only one Dealer, and one Dealer can have many Cars, therefore DealerID should be in Car table. Also Car can be only one Model, but there are many Cars the same Model. It looks quite normal to put ModelID into Car table, and I don't see any possib

I forgot to add Video (This has all the Primary key id from the tables below) Now does it work? My question is how do I get the Primary keys into the video table? Do I just put them in and the database will know it should look in the other tables? How do I connect it? I read some books bu

Re: Normalization sql

Hi John, your design is normalized, but incomplete and unconnected. Where do you put the information which actor was playing in what title, which title was done in what studio etc. ? Normalization is a representation technique to avoid storing *redundant* information. But first this informati

Re: Normalization sql

You're starting off ok, just missing the links between the tables. I would suggest for simplicity though that you change the names of your PKs to reflect their table, i.e. Title (VideoTitle, Details, TitleID). Otherwise once you do multi-table queries joins you will have to specify the table names

Re: normalization question

Hi Daren, How long do you need to store this information? The normalized table that you describe is simple and easy to index. Having several million rows in the table won't bother MySQL. So is it sufficient to keep the data around for a month and then prune it out of the database? Long term
