Using the above table structure, create a normalized Entity-Relationship Model (ERM). Identify Primary Key(s) and Foreign Key(s) for all the entities, connectivities and/or cardinalities, and relationships between the entities. As for Chen's ERM notation and the normalization, the level should be in Third Normal Form (3NF) and above. [Note: you do notneed to show the normalization process such as the functional dependency diagram.]

Part 3: Denormalization – Pick one of the three common relationship types that often give an opportunity for denormalization (one-to-one; many-to-many with non-key attributes; reference data (1:N)), and make up a possible scenario that would fit it. Provide the normalized relations that represent your scenario. Now, show the resulting relation(s) if you were to denormalize what you provided above. Explain the advantages and disadvantages to what you did in (b). Or, if you were not able to denormalize, justify why it was not possible.

Please provide a list and illustrative example for the three forms of binary relationships that are not covered in this book. Draw a regular E-R diagram as well as an IE Crow's Foot E-R diagram for each of the three cases studied here.

Use the technique of normalization to validate the structure of your relational schema. Demonstrate that each of your relations is in third normal form (3NF) by displaying the functional dependencies between attributes in each relation. Note, if any of your relations are not in 3NF, this may indicate that your ER model is structurally incorrect or that you have introduced errors in the process of deriving relations from your model.

Using the relations ATTACHED, normalize your relations into first, second, and third normal forms. First, KINDLY describe the changes required to your relations to meet the standard of the first 1NF and then 2NF and lastly 3NF. Then, you should provide an Entity Relationship diagram that is in 3NF. All attributes, entities, keys, and relationships should be included and labelled. Hint: Remember that in the hospital software system, the “Patient” relation includes the “medicines” attribute and the “Appointment” relation includes the “allergies” attribute. Allergies describe a list of any known allergies and medicines describe a list of medicines prescribed for a patient.   Please add:   Define or describe the changes required to get the relations into the 1st normal form. Define or describe the changes required to get the relations into the 2nd normal form. Include an Entity Relationship diagram in the 3rd normal form. The primary and foreign keys, at a minimum, are defined for each…

When mapping generalisations and specialisations in enhanced entity relationship diagrams, which solution will deliver the least redundancy and allow representation of the most specialisation types. Select one: a. Multiple relations representing subclass entities only. b. A single relation containing a type attribute. c. Multiple relations representing both superclass and subclass entities. d. A single relation with multiple boolean type attributes.

Please! can you help me with only Relationship Analysis for this scenario. I have attached another screenshot to followup with data

Explain the ambiguity in the definition of the term weak entity. Explain how this book interprets this term

Convert the ER diagram to relations in the normal manner to capture as many constraints as possible, and then identify which of the answers is a relation schema. A. Dependents(ID, name, bDate) B. Employees(ID, name, street, city, state, phones, sDate, lengthEmp) C. Coverage(ID, name) D. Employees(ID, name, street, city, state, sDate, lengthEmp)

Design an Entity-Relationship for each system described below. Use the (min,max) notation. State clearly any additional assumptions you make. Give the relational model by applying the mapping rules (WITH REFERENCES AND ARROWS). NOTE: USE CHEN ER DIAGRAM (YOU CAN USE VISIO MICROSOFT(TEMPLATE=CHEN) ONLY SHOWING THE ENTITIES/ATTRIBUTES/WEAK ENTITIES/RELATIONSHIPS/PRIMARY KEY-FK/ (MIN-MAX) NOTATIONS ALSO NOT FORGETTING THE REFERENCES ON THE MAPPING TABLES WITH ARROWS REFERRING THE FOREIGN KEYS. YOUR WORK SHOULD BE SPECIFIC WITH JUSTIFICATION.   Consider a Mail_Order database in which employees take orders for parts from customers. The data requirements are summarized as follows: The mail order company has employees, each identified by a unique customer number, first and last name, and ZIP code. Each customer of the company is identified by a unique customer number, first and last name, and ZIP code. Each part sold by the company is identified by a unique part number, a part name, price,…
