Question

A record company wishes to use a computer database to help with its operations regarding
its performers, recordings and song catalogue. A requirements analysis has elicited the following
information:
Songs have a unique song number, a non-unique title and a composition date. A song can be written
by a number of composers; the composer’s full name is required. Songs are recorded by recording
artists (bands or solo performers). A song is recorded as a track of a CD. A CD has many songs on it,
called tracks. CDs have a unique record catalogue number, a title and must have a producer (the full
name of the producer is required). Each track must have the recording date and the track number of
the CD. A song can appear on many (or no) CDs, and be recorded by many different
recording artists. The same recording artist might re-record the same song on different CDs. A CD
must have only 1 recording artist appearing on it. CDs can be released a number of times,
and each time the release date and associated number of sales is required.
Use this information to design an appropriate EER model (If any assumptions then write those also),
also convert EER model to tables with proper justification.A record company wishes to use a computer database to help with its operations regarding
