Table 4-8 shows a portion of a shipment table for a large manufacturing company. Each shipment (identified by Shipment#) uniquely identifies the shipment Origin, Destination, and Distance. The shipment Origin and Destination pair also uniquely identifies the Distance.
Question:
a. Develop a diagram that shows the functional dependencies in the SHIPMENT relation.
b. In what normal form is SHIPMENT? Why?
c. Convert SHIPMENT to third normal form if necessary. Show the resulting table(s) with the sample data presented in SHIPMENT.
Kindly find attached.
Normalize the relations into first, second, and third normal form.
First, describe the changes required to your relations to meet the standard of 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 labeled.
Hint: (Attached)Remember that in the hospital software system, the “Patient” relation includes “medicines” attribute and the “Appointment” relation includes “allergies” attribute. Allergies describe a list of any known allergies and medicines describe a list of medicines prescribed for a patient.
It should define or describe the changes required to get the relations into the 1st normal form.
It should define or describe the changes required to get the relations into the 2nd normal form.
It should include an Entity Relationship diagram in the 3rd normal form.
The primary and foreign keys, at a minimum, are defined for each…
Develop an Entity Relationships Diagram (ERD) based on the relational schemas in the 3NF for the starting relational schema in un-normalized form presented below.

For example, ‘Spanish level 1’ is offered on Monday mornings, Monday evenings or Wednesday evenings, and runs over 25 weeks from October to March. On the other hand, ‘Introduction to Digging Up Your Ancestors’ only runs for 8 weeks, but is offered on Tuesday or Wednesday evenings from October to December, January to March, and April to June, with an optional field week in August. There is always a maximum number of places for each course offering, which is dependent on the individual teacher. For example, ‘Spanish level 1’ on Monday evenings may be limited to 20 places, but on Wednesday evenings the limit may be 25.
