Urgent 5

Part 1. Find at least two journal articles in your discipline (e.g. informatics, information systems, IT) that have a similar problem that you are attempting to solve in your systems analysis and design project for this course.  Use a minimum of two scholarly journal articles from top information systems, informatics, or information technology journals to support your systems analysis and design methodology.
In one paragraph each, describe the design methods and processes the authors of the articles justified to attempt to solve the underlying problem(s).  For example, did they use a framework or standard to benchmark and test their systems analysis and design?  Your methodology is the blueprint that you will follow to compare the old system to the new system in the results of the final phase of the project.  It needs to be objective and enable a proper benchmark that adequately compares the systems.  For example, you could use ACM, ANSI, ISO, ITU, NIST, and/or information standards like HIPAA or PCI.
Part 2. Include at least four unique systems analysis diagrams from your systems analysis project for peer review.  Diagram 1 must be a written use case / use case description of the existing system.  Diagram 2 must be a written use case / use case description of the new system. Diagram 3 must be an activity diagram of the existing system.  Diagram 4 must be an activity diagram of the new system. Do not attach the diagrams, embed them into your post as a video

ratings list

use the for statement to iterate on the ratings list and subtract each rating score by 3.5, then store the subtracted value inside a new list.

use this list of rating scores: 2,2,3,3,3,4,4,4,5,5

Pseudocode:

Set the variable with the list of rating scores

Initialize a list variable named mean deviations

Use the for statement to iterate through the rating scores

Subtract the score by 3.5 then store it in mean deviations.

Display the mean deviations list.

2) Write a program that determines the value of the coins in a jar and prints the total in dollars

and cents. Read integer values that represent the number of quarters, dimes, nickels, and

pennies. This program will require user input, output needs to have the correct currency

format without using the currency formatting code.

Probability Theory and Introductory Statistics

Find a dataset (must have multiple columns with data at the interval or ratio measurement level), and examine and test the relationships between several variables. Provide the R codes in the R-script file under the sub-heading Module 5, and the statistical outputs under the sub-heading “Module 5” in the Word file. In general, your statistical outputs should be titled and labeled so that they can stand on their own (and can be understood by anyone who looks at them for the first time).

  1. Produce and export at least one correlation table or correlation chart. A correlation chart is diagnostic, and should not be larger than 5 variables for reporting purposes. Why is this? Provide several sentences describing the key analytical findings.

What is the Best Way to Connect an Office?

Think of a modern technical support call center. In a call center, there are people who answer phone calls and provide support to end users. Their phones are typically integrated onto the network and/or their computers. Each phone needs a certain amount of bandwidth, and their computers need bandwidth. There are also managers who use the same technology but to a lesser degree, and support staff who manage the office and keep things running smoothly.

Now, move this office from the modern class and cubicle building to an old 1960s office building in Florida. Each office is a concrete block bunker, each team member has their own office, and the walls have SAND for insulation. (No joke – this is super common.) Also, there is a lining of asbestos in the ceiling and floor, so disturbing anything is a major nonstarter. Now, design the network for this call center so it can effectively operate.

Some data to help you out:

  • The instructor feels sorry for any network administrator who needs to operate this network, so this isn’t something we should do in the real world
  • Students are welcome to recommend commercial-grade solutions, but consumer-grade solutions will also receive perfect scores
  • The computers do not have Wi-Fi cards, and most connect using ethernet cables. You need to recommend switches that can work in mesh mode or client mode
  • There are 20 individuals working in the office
  • Each computer requires 50 Mbps of network connectivity during use
  • Each phone requires 0.5 Mbps (VOIP ethernet connection required) 
  • The computers utilize technology in a data center that hides how the phones and computers communicate
  • Phone communications are much more important than computer communication. The phones reboot if they cannot contact the VOIP server for two seconds
  • Telephones are on vlan 1234
  • Computers run on vlan 1235
  • The building has a 10-Gbps connection to the server room, and each access point has multiple 1- or 10-Gbps connections to the switch. This connection to the switch may have a single vlan or both vlans applied to it
  • The project has a $20,000 budget

With this information, design a wired and wireless network solution for this building. Remember, the users are separated by concrete block and SAND.

Parameters: Submit a one-page description of your solution. The solutions must include prices for all products and a two-sentence description of why each product was chosen. The solution must be complete, including, at minimum, ethernet cables, switches, wireless clients, and wireless access points.

Using PhoneGap to Simulate a Derby app

 PhoneGap allows developers to work with essentially the same tools (HTML, CSS, and JavaScript) used for creating and maintaining websites. Even though PhoneGap applications are created using this toolset, native environment components and SDKs must be installed for each platform for which an app is being developed. For example: to develop for the iOS platform, xCode and its SDKs must be installed (see chapter 7). These native components will install as part of the PhoneGap environment during setup. When Adobe supported the PhoneGap framework, an installation file would be downloaded which made the setup process simple. Adobe announced discontinuance of PhoneGap as of October 1, 2020 (see www.phonegap.com/start). PhoneGap is now a free and unsupported product. Like our experience last week, this makes our usage and preview of PhoneGap this week somewhat limited. I want to again start with the user interface for a PhoneGap application (p. 331). The requirements for the Derby app is to provide two pages; one that lists all of the teams/leagues and one that lists all the players. When a league/team is selected, the application shows the roster for the team. When a player is selected, it shows which team the player belongs to an his/her number.
For our assignment this week ( Assignment 9), you will need to simulate two interfaces/screens – one list the Derby teams ( Figure 11:27, p. 333) and one list a Derby roster ( Figure 11:28, p. 334). Every screen in PhoneGap is another HTML page – you will create your screens using HTML. On a website, the “index file” holds the HTML content for the main page. Different tags (head, anchor, page, Div, numbered and unnumbered list, etc.) are wrapped within HTML/BODY code to give the page its features. Cascade Style Sheets (CSS) can be embodied within the HTML to give dynamic customization/style to pages, and JavaScripts provide animation or interactive functions. Our authors provide examples of  HTML script and useful javaScript Libraries from which you can leverage for your simulation. Your goal is to use HTML to simulate two diferent screens for your Derby app.

  • Download and install Figma (can use comparable SW of your choice) on your computer. This is same as last week.

Make one screen shot here that shows you have install the Figma wireframing tool (or a comparable tool of your choice)You are ready to start adding HTML content (to your interface/screens) that match the two figures above* Your app/interface is using HTML, CSS, and JavaScript coding, but you ARE NOT required to do/show any coding for this assignment. Look at the appropriate coding that the authors provide and describe the functionality. Remember – ensure that the JavaScript function onDeviceReady is fired (p.324)

  • First, state what platform (iOS, Android, Windows, etc.) you are simulating. Then be certain to mention any particulars that must exist for that platform (see chapters 6 and 7)
  • From the Figma widgets/icons library create a mock interface/screen that follows the (Figure 11:27, p.333) – list of Derby teams Hint: there mut be a scroller, a query, and a storage function like Lawnchair in order for this to work.

Make a second screen shot showing placement of content provided by HTML, CSS, and JavaScript

  • From the Figma widgets/icons library create a mock interface/screen that follows the (Figure 11:28, p.334) – a Derby roster 
  • List and describe the particular HTML, CSS, and JavaScript libraries you used in creating the functionality that you simulared in your app model

Make a third screen shot showing placement of content provided by HTML, CSS, and JavaScript
