data dictionary, Database Management System

Assignment Help:
The database is to record information about artists for a (music) production company. An artist is the name of a singer or band; the name of the artist, the year the artist started recording, the number of members of the artist and the genre of music it plays are to be recorded. For example, the artist Queen was formed in 1970, had four members and played rock.
In addition to the information about artists the database will also record information about the members of an artist (referred to as musicians). The (unique) SIN, first name, last name, instrument, and email address of musicians is to be recorded. An artist must be associated with at least one musician, although may be associated with more. Musicians that are not associated with artists will not be maintained in the database; a musician may be associated with more than one artist. The database should also record the share of the revenue that a musician receives from songs recorded by an artist that the musician is associated with. If a musician is associated with more than one artist, they may have different shares from each artist. For example, Ian Gillan might receive 30% of the revenue from songs recorded by Deep Purple, and 80% of the revenue from songs recorded by Gillan.
The following information is to be recorded for songs, the unique ISRC (International Standard Recording Code), the song''s title, its duration, the year that it was recorded and the name of the song''s album. Songs are recorded by artists, an artist can record more than one song, and each song must be recorded by just one artist. Since the database may record artists that are just starting out an artist does not have to have recorded any songs.
Monthly sales of songs will also be recorded. For each month, year, vendor, and country the number of songs sold, and the total sale amount are to be recorded. For example, the song "Further Away" might be sold by iTunes Canada, iTunes UK, and Amazon Canada in September 2017, so would require three sales entries that record the number of songs sold and the total amounts for those vendors and countries in that month. A song may be sold many times (or, sadly, not at all).
The record labels assign each musician associated with an artist a representative (rep). A musician is assigned at most one rep for each artist that they are a part of (and may not be assigned any reps at all). A rep must be assigned to at least one musician and can be assigned to multiple musicians or even the same musician more than once if that musician is associated with multiple artists. A label representative has a (unique) SIN, first name, last name, label name and phone number. For example, Paul Rodgers might be associated with rep Bob for Free (who recorded the classic All Right Now) and rep Kate for Bad Company.
Finally, the writers of songs are to be recorded. A song may have more than one writer but must have at least one. Writers of songs not in the database (or prospective writers) will not be recorded. A song writer may write many songs. In addition to the writers'' SINs, first names and last names the percentage royalty that they earn for each song should be recorded. These royalty percentages may vary from song to song.
