Scenario
The exam unit uses the system after the subject registration period has closed. The system will display a list of subjects that have registered students. Using this list, the exam unit will plan out examination week. Examination week lasts 6 days, from Monday to Saturday. For each day, the exam unit will assign a subject to that day. Each day can have a total of 6 examination hours with subjects having 2- hour or 3-hour examinations. For example, if the subjects are 2-hour examinations, then 3 of them can be scheduled for the day and if the subjects are 3-hour examinations, then only 2 of them can be scheduled for the day. There can also be a mixture of 2-hour and 3-hour examinations. If the exam unit schedules too many examination hours for that day then the day resets and the exam unit needs to reschedule again.

Business Rules:
Each musician at NewTalent should have a name, address, and phone number on the system. The Instruments used in the songs have a unique name, musical genre (i.e. rock, pop, hip hop), and type (i.e. string, piano, guitar). Every album recorded under the NewTalent label has a title, copyright date, format, and an album identifier. Each song recorded has a title and an author. Musicians can play several instruments, and an instrument can be played by multiple musicians. Every album contains several songs, but a song can only appear on one album. Songs are performed by one or more musicians, and a musician can perform numerous songs. Each album has one musician acting as its producer, although a musician can produce multiple albums.

An Art Museum needs to keep track of its artwork and exhibitions. The museum has a collection of
artwork. Each piece of art has a unique id [ArtID], an artist, year and title.
Artwork is categorized by type. There are two types, paintings and sculptures. Paintings have a
paintType and style. Sculptures have a material, height and weight.
Artwork is frequently shown in exhibitions. Each exhibition has a unique name, startDate, endDate.
A listing of the artwork displayed at an exhibition is also retained.
Below is an E-R diagram for a database to help the Art Museum. Provide appropriate names for
entities E1, E2, E3, E4 identifiers 11, 12, 13, 14 missing attributes and relationship cardinality RC1
and relationship type RT1.
