Lab 3: Normalization Assignment: Problem #11 from Chapter #6. (Be sure to note that this is PROBLEM and not REVIEW QUESTION). Normalize a set of data to 1st, 2nd and 3rd normal form by creating relational schemas, dependency diagrams and an Entity Relationship Diagram (crow’s foot notation). For this lab, complete problem #11 in Chapter 6. Be sure to complete each letter (a thru c) for the problem. The ERD for letter cmust be completed with the use of Microsoft Visio.

Question 1: Normalization PLEASE WRITE ELIGIBLE AND SHOW FULL STEPS FOR DIAGRAM TO DECOMPOSE Consider a relation X with six attributes WYSMFE where WS is a composite primary key for X. Assume X has the following functional dependencies (X is one table with the attributes W, Y, S, M, F, E): WS è YMFE S è YME E è M Is it possible to decompose X into a number of relations in order to achieve a higher normal form? Explain how (this means using English sentences and a diagram showing the final relation(s)).
Normalization Show all the steps as you perform normalization for each problem up to 3NF. State your final relation to schemas in 3NF.
Give a Relational Model that corresponds to the Entity-RelationshipDiagram in Figure 1. You must present this model as a RelationalDatabase Schema and not as a diagram. Primaryand foreign keys must be declared where required. Please keep thenames of attributes and role names where required and do not re-place them with different names. Provide NOT NULL constraintsonly where semantically justified by the Entity-Relationship diagram.
Explain how functional dependencies can be used to indicate the following:• A one-to-one relationship set exists between entity sets student and instructor.• Amany-to-one relationship set exists between entity sets student and instructor.
So i wanted to understand how to make a relational database schema diagram, form an EER digaramSo i have EER diagram ( image bellow) and the question is :1.Make a relational database schema diagram:i made one ( image down ) but i dont think that this is a relational database schema diagram....
Transform into relational model (relations). IMPORTANT: The diagram needed for the second part uses a different notation for cardinality constraints. You can deduce the notation from the following: Each employee can work for exactly one department, and each department can have at least one employee. Each department has exactly one manager, and each employee manages at most one department. Each employee has at most one supervisor, and each supervisor can have several supervisees.
