CMIS 320 Project 1
Write a justification paper, of at least 2 pages, to your boss explaining how a relational database solution can be applied to a current business problem or area for improvement. Assume that your boss knows nothing about relational database theory. The goal of this paper is to obtain your boss's approval to proceed with your stated project. Do not focus on technical aspects of a database management system. Focus on how the information will be captured, manipulated, managed, and shared, and the value the database brings to the organization. Include brief examples of how other industries (both domestic and international) have successfully used relational databases to increase efficiency.

Homework 5: Lists

Please show code in Pycharm

The task is to create the following three functions to demonstrate techniques for working with lists:

1. greatestPair(x), which accepts a list of numbers x and returns the index position of the greatest adjacent pair. For example, if the list [4, 3, 8, 0] was passed to your function, it would return 1, as that the values 3 and 8 form the greatest adjacent pair in the list. Your function should return None if passed an empty list.
2. isSorted(x) that takes a list of numbers and returns True if the list is sorted (either smallest-first or largest-first) and False otherwise. Your function should return None if passed an empty list.
3. intersection(x,y) that takes two lists x and y as parameters and returns a new list containing the intersection of the two parameters (all elements that are common to both x and y). The returned list should not contain duplicate values.

Discuss the advantages and disadvantages of using DHCP.

write code using Arduino to display the digits of pi(π) to the 20th decimal point on a 7-segment display. You code should include functions for all the digits, and your loop( ) should only call the functions to display the numbers. Delay 500ms between each number. Use macro definitions for the individual LED's.

One customer has sent you the following email to initiate a project.

“I need to make a report program manager using the internet data from internet system. I only need the data related to signal strength and customer satisfaction rating. I need to be able to sort this by state.” What are the followup questions, and what research you would do before meeting the program manager with the customer what information would you add on the requirement document.

This question is about providing game logic for the game of craps we developed its shell in class. At the end of the game, you should ask the user if wants to play another game, if so, make it happen. Otherwise, quit

**Provide the working output of this game and the picture of the output. **

This is an implementation of the famous 'Game of Chance' called 'craps'.
It is a dice game. A player rolls 2 dice. Each die has six faces: 1, 2, 3, 4, 5, 6.
Based on the values on the dice, we play the game until a player wins or loses.
You add the values of the dice's face.
1) If the sum is 7 or 11 on the first roll, the player wins.
2) If the sum is 2, 3, or 12 on the first roll, the player loses ( or the 'house' wins)
3) If the sum is 4, 5, 6, 8, 9, or 10 on the first roll, then that sum becomes the player's 'point'.
4)To win, the player must continue rolling the dice until he/she 'make the point'.
5)If the player rolls a 7 he/she loses.

Python 2.7 Question: If-Else Statement

Is there a way for me to ask the user a series of questions with an if-else statement? For example, if a statement is true ask these questions, if false ask these questions. This is what I have so far:

if user_input == "yes ":

ques.check_string("Enter Name: ")

ques.check_string("Enter email: ")

elif user_input != "yes":

ques.check_string("Enter Name:  ")

ques.check_string("Enter phone number: ")
  

As a programmer, you have been asked to write a Java application, using OOP concepts, for a Hospital with the following requirements:
• The Hospital has several employees and each one of them has an ID (int), name (string), address (string), mobile phone number (string), email (string) and salary (double) with suitable data types. • The employees are divided into:
o Administration staff: who have in addition to the previous information their position (string). o Doctor: who have also a rank (string) and specialty (string).
The project requirements: • You will need to create all the needed Java classes with all the required information. • You have to apply all the OOP (Object Oriented Programming) concepts that we have covered in this
module (i.e. inheritance, polymorphism, interface and collections)
• Include a Microsoft Word document (name it as readme.doc) that includes several screenshots of
your Netbeans IDE application GUI interface as well as the output screenshot results. Provide all
assumptions that you have made during design and implementation.
• Include the whole Netbeans Java project with all source codes. Write as much comments as possible

At the end, you will need to create a testing class (e.g. Hospital.java) with the static main() method with the following requirements:
• It must have an initial fixed collection of working staff (at least 3 administration staffs and 2
doctors)
• The program will print a selection screen where the user can choose the operation
he/she wants to perform. The selection screen will be repeated after each selection until the staff
type the number 4 to completely exit from the program:
1. Add an administration staff (by providing all her/his information) to the list of all
administration staff
2. Add a doctor (by providing all her/his information) to the list of all doctors
3. Print all working staff (remember to differentiate between administration staff and doctors
in the output printout
4. Exit the program

simple python program : include comments please

Let's continue to practice an example using the PriorityQueue from the queue module in Python:

Suppose you have been tasked with writing a program that will track the registration waiting list for CCIS 100. Priority is given to seniors, then juniors, etc...

1. Generate a text file (named waitlist.txt) containing the number of credit hours earned, ID number, and email of students who request to be added to the waitlist (1 piece of data per line).  The file can contain any number of students, but, at minimum, should contain at least 10 students.
2. Read that information into a list of tuples
3. Using a PriorityQueue, print the order in which the students should be added to the course if slots open up. Please make sure that the data is printed/formatted in a table with column headings.

Define a regular expression that will correctly (and exactly) match a valid Gregorian calendar date of the form MM/DD/YYYY (with leading zeroes for single-digit months and days) (and ONLY dates in this format). • Months 1, 3, 5, 7, 8, 10, and 12 have 1–31 days • Months 4, 6, 9, and 11 have 1–30 days • Month 2 (February) has 1–28 days (ignore leap years) • Assume that the year falls into the range 1900–2099 HINT: You may find it helpful to define several patterns and combine them using the alternation operator.
