In this task, you will perform normalization on a crude table so that it could be stored as a relational database.
ryzh [129]

Answer:

Check the explanation

Explanation:

(1.) The functional dependencies based on assumptions are as follows:-

Trip determines which staff was there in the trip, the car used for the trip, the quantity of fuel used in the trip, the fill up time and the total paid of the trip.

Service station refers to its address

Car details consist of the details of license plate, odometer reading and the fuel type used in the car

fuel type and the fill up time will help to determine the cost of the fuel at that time

cost of the fuel and the quantity of fuel used will determine the total paid

From the above assumptions the functional dependencies are as follows:-

Trip ID -> Staff Name, Car Details, Service Station, Quantity, Fill Up Time, Total Paid

Service Station -> Station Address,

Car Details -> License Plate, Odometer reading, Fuel Type

Fuel Type, Fill up Time -> Cost per litre

Cost per Litre, Quantity -> Total Paid

(2.) Initially the relation is as follows:-

R (Trip ID, Staff Name, Car Details, License Plate, Odometer Reading, Service Station, Station Address, Fill up Time, Fuel type, Quantity, Cost per Litre, Total Paid)

For 1 NF there should not be composite attributes,in the above relation Staff Name and Station Address are composite attributes therefore it will be decomposed as follows:-

R (Trip ID, Staff First Name,Staff Last Name, Car Details, License Plate, Odometer Reading, Service Station, Street, City, State, Zip Code, Fill up Time, Fuel type, Quantity, Cost per Litre, Total Paid)

For 2 NF there should not be partial dependency that is non prime attribute should not dependent upon any 1 prime attribute of candidate key, since in the given relation there is only 1 candidate key which is only Trip ID, therefore the relation is already in 2 NF.

For 3 NF there should not be transitive dependency that is non prime attribute should not dependent upon the other non prime attribute, if it is present then the relation will be decomposed into sub relations, the given relation is not in 3 NF therefore it will be decomposed as follows:-

R1 (Trip ID, Staff First Name, Staff Last Name, Car Details, Service Station, Quantity, Fill up time, Total paid)

R2 (Service Station, Street, City, State, Zip Code)

R3 (Car Details, License Plate, Odometer reading, Fuel Type)

R4 (Fuel Type, Fill up Time, Cost per litre)

R5 (Cost per Litre, Quantity, Total Paid)

(3.) After the 3 NF we add the primary and foreign key constraints as follows:-

R1 (Trip ID, Staff First Name, Staff Last Name, Car Details, Service Station, Quantity, Fill up time, Total paid)

R2 (Service Station, Street, City, State, Zip Code)

R3 (Car Details, License Plate, Odometer reading, Fuel Type)

R4 (Fuel Type, Fill up Time, Cost per litre)

R5 (Cost per Litre, Quantity, Total Paid)

In the above relational schema the primary keys are represented with bold and foreign keys by italic

(4.) The ER diagram of the above relational schema using crow's foot notation are as shown in the attached image below:-

Sati [7]

Answer: Option C : Make a decompression stop that splits the difference between what your buddy's computer requires and what yours does.

Explanation:

Dive computers are battery-powered computers within a watertight and pressure resistant case. These computers track the dive profile by measuring time and pressure.

hence, making a decompression stop that splits the difference between what your buddy's computer requires and what yours does is the best option.

Why is it necessary for engineers, designers, and technologists to make sure that their drawings are fully dimensioned?
Flura [38]
<em />It is necessary, because when engineers build the design or model, they need to make sure that it does not turn out 2 dimensional but,also so that they can make their"project"more accurate and not just up or whatever."As a general guideline to dimensioning, try to think that you would make an object and dimension it in the most useful way. Put in exactly as many dimensions as are necessary for the crafts person to make it -no more, no less. Do not put in redundant dimensions. Not only will these clutter the drawing, but if "tolerances" or accuracy levels have been included, the redundant dimensions often lead to conflicts when the tolerance allowances can be added in different ways.
<span>Repeatedly measuring from one point to another will lead to inaccuracies. It is often better to measure from one end to various points. This gives the dimensions a reference standard. It is helpful to choose the placement of the dimension in the order in which a machinist would create the part. This convention may take some experience."This may or may not help but it will give you an idea to what your looking for.</span>
