reate 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 dont 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.
