Question
Below is a sample of an assignment roster of employees working in a company. An assignment
involves a specific job given to a specific employee, on a specific date and time, and in a specific
section of a specific building. Very specific.
You've identified the following entities: Assignment, Employee, Section, Building, Job. No
others.
Use the information below to infer which entities have relationships with each other, as well as
the types of those relationships, and constraints if any.
All that you should submit is a set of the relevant business rules. Once again, remember
that entities don't necessarily directly connect, unless the information collected specifies that
they are connected.
In case you need extra info:
●
Section is a kind of code given to a section in a specific building. Each section has a
completely unique code (across all buildings) e.g. F3 only exists in building "Flora", not any
other building.
●
Section N is short for "section name"; it's the name of the section
Each employee has a single supervisor, regardless of where/what they are assigned.
Building N is a unique number given to a specific building.
Supervisor No is actually just the Employee No of the Employee that supervises a given
Employee
Hint: Since the Supervisor is actually just an Employee, the relationship "Supervises" is a
relationship between employee and another employee i.e. a business rule in which both entities
referencing are "employee".
