A company creates a database for its customers in which each customer is identified by their phone number. In this discussion, explore whether or not this is a function with your classmates. In your first post, address the following:

1. Assign one variable as the input and the other variable as the output for this scenario. Is this relation a function? Justify your answer using the definition of a function, and explain your reasoning carefully.
2. Do you think this is a good setup for the company’s database? Describe any pitfalls you see in this setup.
3. Suggest an alternative identification system for the company’s database.

Q3. Convert the conceptual database into a relational database schema. Identify the primary key and foreign key constraints.

Q4. Show all the functional dependencies that should hold among the attributes.

Q5. Design relation schemas for the database that are each in 3NF. Specify the primary and foreign key attributes of each relation.

Hi expert!

Can you help me with the above questions? I'm not asking you to solve my questions but want to find what each questions actually requires me to show or answer.

f) If this firm shuts down in the Short Run, determine its profit maximizing/loss minimizing profit amount. Please explain your answer.

g) What should this firm do in the Short Run in order to maximize its profits/minimize its loss (produce or shut down)? Please explain your answer using numbers.

h) Explain what this firm should do in the Long Run. Why?

Declare whether each below is True or False. If you say False for any statement, you must explain clearly your reason for answering False in order to receive credit.

f) Since Monopolies have no competition, they will not pay for advertising.

g) The market sets the price for Oligopolies.

h) Product Differentiation provides no benefit to society.

Python pls

1. The function only allow having one return statement. Any other statements are not allowed. You only have to have exactly one return statement.

For example

the answer should be

def hello(thatman):

return thatman * thatman

1. Create a function search_wholo function. This function returns a list of 2 tuples, which people and their excitement skills, and sorted by decreasing excitement level(highest excitement skill first). If two people have the same excitement level, they should appear alphabetically. The list includes people who have the same hobby as an argument, and greater than or equal to the excitement level(which argument also).

For example

database = {'Dio': {'Lottery': 2, 'Chess': 4, 'Game': 3},'Baily': {'Game': 2, 'Tube': 1, 'Chess': 3}, 'Chico': {'Punch': 2, 'Chess': 5}, 'Aaron': {'Chess': 4, 'Tube': 2, 'Baseball': 1}}

def search_wholo(database, hobby:str, num: int):

# ONLY ONE STATEMENT ALLOWED (RETURN STATEMENT)

search_wholo(database, 'Chess',4) -> [('Chico', 5),('Aaron', 4), ('Dio',4)]

search_wholo(database, 'Game',0) -> [('Dio', 3), ('Baily', 2)]

search_wholo(database, 'Tube',3) -> [] #because all people's excitement skill for tube is lower than 3

search_wholo(database, 'Gardening',3) -> [] #because there is no "gardening" hobby in the dictionary

This is a simple list table of a company trying to keep track of parts that they sell and orders that came in purchasing those parts (in other words, not a database but a flat one table file). You will design a database for this company so that they won’t be relying on a simple 1 table list system to keep track of their data. Looking at the table below, produce the 3NF of the data.

Create the database in an actual database application (i.e Microsoft Access, MySQL or Oracle, etc.). You must use SQL commands to create the tables in the database (i.e Create Table command). Submit the SQL commands with the completed database as part of the assignment. The tables should be populated with records from the scenario you chose.

In 2000, The James Bond Company purchased all of the stock of the 007 Company at book value

In 2000, The James Bond Company purchased all of the stock of the 007 Company at book value. James Bond accounts for this investment using the initial value method and 007 Company does not pay any dividends.

On 1/1/2015 The James Bond Company issued (sold) 400; 10% $1000 bonds for $440,000. These 20 year bonds pay interest each July 1 and January 1. James Bond Company uses straight line amortization for bond interest

On 1/1/2018 The 007 Company purchased all of these bonds in the open market for $417,000. 007 Company uses straight line amortization for investment interest revenue

REQUIRED:

A) Make the journal entry James Bond Company makes when it sells the bonds in 2015

B) Make the journal entry James Bond makes on July 1 2015 with the first interest payment

C) Make the journal entry 007 Company makes when it buys the bonds in 2018

D) Make the journal entry 007 Company makes on July 1, 2018 when it receives its first interest payment

E) Make the worksheet entry needed in 2018 connected with these bonds

F) In 2018 James Bond reported unconsolidated income of $600,000 and 007 Company reported income of $80,000. What is consolidated income?

G) Make the worksheet entry needed in 2019 connected with these bonds h) In 2019 James Bond reported unsolidated income of $600,000 and 007 Company reported income of $80,000. What is consolidated income?

Last weekend I tried to water ski for the first time in my life. I ended up with a sprained lower back? What organ systems have suffered damage? [with citations ]

A patient comes into the hospital complaining of severe pain in the right side of her abdomen. A nurse palpates her right region and notes the location of the pain on the chart as  being the RLQ. What possible organs could be the source of the pain? [with citation]

1. You’ve implemented the Academic Database in a local school in your community. The school’s administrator decides, there’s no need for database backup and recovery plan because all their computers are new. Explain in 100 to 150 words why there needs to be a disaster recovery plan.
