Describe how functional dependencies may be used to show: • There is a many-to-one connection set between the entity sets student and instructor, as well as a one-to-one relationship set between the two.

Break down the concept of inherited attributes and how they work in the context of interconnected objects.

Given relation R(u, y, c, d, e, f, w) where there are two keys: {y,c} and {w}. Given a set of functional dependencies F = {fd1: {y,c} -> {u,d,e,f,w}, fd2: u -> c, fd3: w -> {u,y,c,d,e,f}}. Is R in 3NF? Explain why.

Create an Entity-Relationship Model to represent the data requirements of the problem given below. Specify the cardinalities of relationships and all-important constraints. Also mention the assumptions if you have made any. [20 Marks] A person can be an employee, alumnus or a student. For person P_id (identifier), date of birth, gender and contacts are stored. Person can have more than one contact numbers and there are no other types of person that exists. An instance of person can belong to more than one type. Date hired and salary is the unique attributes of employee. For alumnus degree is required to be stored that comprises of year and designation. Major department is the attribute of student. A student can be a graduate student or an undergraduate student but not both at the same time. No other type of student exists. For graduate student test score is stored and for undergraduate student class standing is stored. Employee can be faculty, staff or others but not both at the same…
