Question details
create a 3NF entity relationship data model based on the scenario presented below
Read the following paragraph and create a data model for the
business under discussion. “My partner and I own an independent
record store. Well, I guess record store is really the wrong term
these days since we really don’t sell a lot of records anymore. We
sell mostly CDs, but also some tapes. And yes, we do stock vinyl
records, too. Regardless of format (that is, CD, tape, or record),
we sell long-playing albums as well as singles. Every item we sell
is priced, and we keep track of the number of each individual title
in stock on a daily basis. We like to track sales by both title and
recording artist. The sales information by title needs to be
tallied weekly to send to external ratings services so they can
compile their best-seller charts. We often get customers who ask us
to find certain songs for them. For singles, this is fairly easy
because the title of the single is the title of the song. Some
singles have multiple songs on them, though. Albums, on the other
hand, comprise
multiple songs. We need the ability to search for titles by song to
let customers know which titles (both singles and albums) contain
the songs they are looking for.”
