Suppose you are building a Java application for storing the names and ages of children in a family. Describe the strategy that you would use in order to determine the data types you would need for your application. Provide three data elements and the corresponding data types that you would use in your application. Provide a rationale for your response and provide constructive feedback on strategies and rationales posted by your peers.

The purpose of this assignment is to create a data story and communicate findings to key stakeholders.Part 1: For this assignment, you will use the "Arizona Incomes by Zip Code" dataset. You will use Tableau to create a data story that illustrates the median household incomes of Arizona residents. The data provided includes all zip codes in Arizona. Each record is a unique zip code. The data includes the following columns:Zip_Code: An Arizona zip code.Metro_Area: Whether or not the zip code is within the Phoenix-metro area.City: The city name of the zip code.Median_Income: The median household income of each zip code based on 5-year estimates (2010-2014) from the U.S. Census Bureau.The marketing manager has asked you to analyze income data for Arizona residents so that leaders in his department can determine the company's advertising strategy. The marketing manager intends to share this data with other decisions makers and the marketing department staff so that everyone has a thorough understanding of how the income information can be used to determine specific target markets in upcoming advertising campaigns. Because most of these individuals do not have a strong understanding of analytics, they must be able gain the information listed below from studying the charts. In the data story, use visualizations, heat maps, boxplots, etc. to describe the following:How do incomes differ across zip codes within the Phoenix-metro area (using geo-mapping)?What is the relative difference in incomes across zip codes within the Phoenix-metro area (use a heat map)?What are the distribution of incomes across Arizona?How do incomes within the Phoenix metro area differ from those outside of that area?Part 2: Demonstrate the ability to communicate the analytics story to key stakeholders, including the marketing manager, by creating a 6-10 slide PowerPoint presentation (with speaker notes for each slide). Use the charts generated in Tableau to illustrate the data story as it relates to the income of Arizona residents. The slides and speaker notes should address the following for each chart presented.What information is the chart providing to stakeholders?Why is the information in the chart important to key stakeholders?How can this information be used in making decisions about how marketing dollars can be allocated?Refer to the resource, "Creating Effective PowerPoint Presentations," located in the Student Success Center, for additional guidance on completing this assignment in the appropriate style.While APA format is not required for the body of this assignment solid academic writing is expected, and documentation of sources should be presented using APA formatting, guidelines, which can be found in the APA Style Guide, located in the Student Success Center.This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.Part 1 Data Story Visuals- Visualizations including heat maps, geomapping, boxplots, and other relevant charts are complete and correct.

Language Use and Audience Awareness (includes sentence construction, word choice, etc.)- The writer uses a varietY of sentence constructions, figures of speech, and word choice in distinctive and creative ways that are appropriate to purpose, discipline, and scope. Mechanics of Writing (includes spelling, punctuation, grammar, language use)-Writer is clearly in control of standard, written, academic English. The power point presentation must be done with lots of visual examples using screan shots from Tableau. IT MUST HAVE COMPLETE SPEAKER NOTES... THIS PRESENTATION WILL BE PRESENTED... THERE MUST BE ALOT OF GOOD WRITING PER SLIDE IN THE SPEAKER NOTES. PART 3... ON A WORD DOCUMENT PLEASE ANSWER EACH OF THESE QUESTIONS IN 150-250 WORDS. QUESTION 1 - Data is useless without the skills to manipulate, summarize, and analyze it. In fact, even after data is summarized into a reporting format such as graphs and tables, it still requires someone to add context and describe the results to fully explain the data. This can be difficult, especially if data is being presented to nontechnical individuals. Describe two techniques that can be used to better describe analysis results to nontechnical individuals. QUESTION 2-When most people think about data reporting or visualization, they think about a nicely crafted graph that will not be interactive with a user. Some new tools, such as Tableau, can create visualizations that can interact with a user with informative pop-up information, more drill-down information, and the ability to export filtered results. Describe two benefits to having a user interact with a standard report. Are there any drawbacks if the user modifies the report?

ITSE-1429 Project Three, Inventory Report This Programming Project allows you to demonstrate your basic knowledge of Object-Oriented Programming and the use of text file input and output. You will use information read from one text file to create instances of a class named InventoryItem. Next, you will read information from a second text file to update information about the quantities of these inventory items. Finally, you will use the information in the list of InventoryItem objects you created and updated to prepare a report that is written to an output file showing the inventory quantities and their total values as well as the overall total value of all these inventory items. Start by designing a class called InventoryItem. This class contains the following private data attributes: item_number, a unique number used to identify each itemdescription, the text description of the itemquantity, the number of items in the inventoryunit_cost, the value of a single unit of this item in dollars and cents The InventoryItem class has the following methods: An initialization method (__init__) that can be used to create an instance of the InventoryItem class. All the data attributes must be specified as arguments. This method guards against initializing the quantity to a negative number.A __str__ method that returns a string displaying the object’s state.A receive_items method that accepts as an argument the quantity of the item to be added to any existing quantity.A ship_items method that attempts to reduce the quantity of the item. This method must not reduce the quantity of an item below zero. If an argument is passed to this method that would reduce the quantity below zero, a warning message will be displayed instead.A set_quantity method that accepts as an argument a new quantity value for the inventory item. This method must also guard against setting the quantity to a value that is less than zero.A get_item_number method that returns the value of the item_number.A get_description method that returns the value of the description.A get_quantity method that returns the value of the quantity.A get_unit_cost method that returns the value of the unit_cost. Place the class definition for InventoryItem in a separate file named “inventoryitem.py” and then include an “import inventoryitem” statement in your program to gain access to the class definition. Your Python program will read and process two input files and create a single output file in addition to limited console output. Your program will read the contents of a file named “items.txt” and use a portion of the contents to initially create and define the inventory item objects. The “items.txt” text file contains the definition of several inventory items. Each record in this file holds the following information in this order: item_numberdescriptionquantityunit_cost The fields in this file are comma-separated. That is, each field is separated from the next field by a comma. Example records for this file look like this: 12345,Ballpeen Hammer,25,18.75 56789,Phillips Screwdriver,120,10.95 24680,Claw Hammer,35,15.98 13579,Box Wrench,48,20.35 Although this file contains definitions for all the items in the company’s entire inventory, your program will only process the subset of records where the value of the item_number is in the range from 20000 to 79999. After creating instances of the InventoryItem class, display a line on the console (screen) reporting how many inventory items were created. Your program will then read and process a file named “activity.txt”. The “activity.txt” text file contains transactions that will potentially change the quantities of individual inventory items. These are the codes used for the possible transactions: “D” Define the quantity of an inventory item“R” Receive an additional quantity of an inventory item“S” Ship a quantity of an inventory item Records within the “activity.txt” text file contain the following comma-separated fields: Transaction code (“D”, “R”, or “S”)item_numberquantity Example records for the “activity.txt” file look like this: D,12345,0 R,12345,100 S,12345,45 Process only records in the “activity.txt” file that effect items you defined earlier (using the “items.txt” file) AND contain a valid transaction code (“D”, “R”, or “S”). Keep track of the total number of records processed as well as the number of records that were skipped either because they did not have a valid transaction code or they dealt with an inventory item that was not defined earlier (using the “items.txt” file). After processing the entries in the “activity.txt” file your program can now display two items on the console (screen) using print statements. You will know and can display the total number of records processed as well as the number of records skipped. The final step in this programming project is to calculate and display the inventory value of each item as well as the grand total of all the inventory items. This information will be written to an output text file named “Report.txt”. The first line of your inventory report will contain your full name and a made-up name for the company such as “The Albatross Company, Ltd.” The second line in your inventory report will contain the phrase, “prepared on:” followed by the current date and time. (I know, go look it up on the Internet.) The third line will be blank. The fourth line in your report is where the heading information begins. Your inventory report will look as much like this as possible: Joe E. Bagadonutz for the Albatross Company, Ltd.
