Music Database A database needs to be developed that keeps track of compact disks, and songs recorded on them, together with authors and performers of the songs. The data requirements are as follows: 1. For each disk, we want to store the disk ID, the title, and the year of production. Disk IDs are unique. 2. A song is recorded on some disk. It has a title and a number that indicates on which track it is recorded on the disk. For each disk, a song is uniquely identified by its track number. 3. For each person that may occur as a an author or a performer we want to store the person ID, the name, and the nationality. Person IDs are unique. 4. Each song has at least one author who is a person. There are different types of authorship, e.g., composer, text writer, or arranger. For each author of a song, we want to store the type of authorship. 5. Each song has at least one performer who is a person. There are different instruments for a performer, e.g., voice, piano, violin. We want to store for each performer the instrument they have played during the recording
