Imagine you are managing a design project that will create an interface for automobile mechanics. The interface would be used by the mechanics to look up various fixes and parts for any number of makes or models of automobiles that may come through their garage. Decide what usability measures would be most motivating when designing this interface and describe the unique challenges you would have to plan for when designing an interface for an automotive repair shop. Use supporting evidence to support your response.

In this homework you will develop software models for a system designed to support a business. You will choose the business and the main functionality of the system as part of Task 1 below. This choice is important as the models you will develop in the remaining tasks must match with your choice. 

Week 4

You are a preschool director, social worker, or friend. A parent tells you that their child loves using a smartphone, iPad, or computer games. The parent is not sure if it is appropriate. How would you respond if the child is a toddler or a preschooler? Using this scenario provide an informed response for each age group that is based on the role you selected (identify which one) and include reasoning for your response including why or why not this is recommended or developmentally appropriate for each age citing your resources.

NOTE- You need to address BOTH age groups in this assignment to demonstrate understanding the developmental differences. You may use the same advising “role” for both.

Paper length 500 words minimum, 2 academic references must be used, MS word or RTF attachment only.

Create a set of UML and Data Flow diagrams. 

This is a required assignment, worth 45 points, and must be submitted by the due date.  Late assignments will not be accepted.

Details on the Project: 

Systems Diagrams and Visualization Project Create the following UML diagrams to visualize the process of completing the IT project from the previous exercise (providing IT services for a new building):

• Use Case diagram 

• Activity diagram 

• Communications diagram 

• Data Flow diagram 

Assume the following basic processes: 

1. Procurement of all resources. 

2. Setup of PCs and network servers. 

3. Deployment and Testing of resources to the IT Area/Office.

4. Deployment and Testing of resources to the Administrative Area.

5. Deployment and Testing of resources to the Conference Room. 

6. Deployment and Testing of resources to the Meeting Room. 

7. Deployment and Testing of resources to the Individual Offices. 

8. Deployment and Testing of resources to the Computer Labs. 

9. Testing of all Other Locations.

• Create a Use Case diagram to show all actors and the basic processes above 

o Procurement, Setup, Deployment & testing of each major location. 

• Create an Activity diagram to show the deployment and testing of resources into the Computer Labs o Network connectivity testing requires interaction between the PC and Network Specialist o Projector connectivity testing requires interaction between the PC and AV Specialist. 

• Create a Communications diagram to show collaboration between the PC Specialist, the Network Specialist, and the AV Specialist during deployment and testing of resources into the Computer Labs. 

o If network connectivity issues arise, the PC Specialist will communicate with the Network Specialist. 

o If projector connectivity issues arise, the PC Specialist will communicate with the AV Specialist. 

• Create a Data Flow diagram to show the Procurement of all resources, based on this additional information:

o The PC Specialist enters all purchases into the Purchase Application system once the resources are purchased. 

o The PC Specialists closes all purchases in the Purchase Application system once the resources are received.

 Assignment Details

In Unit 2, as we enter the phase of our enterprise architecture implementation we must consider the various approaches required to implement enterprise software and system integration. Regardless of what plan is followed, Quality Assurance (QA) is an important consideration in enterprise system integration.

Choose one QA responsibility typical to an integration project execution. Discuss the specific quality metrics usually implemented during the integration phase of a project.

400 WORDS

Responses to Peers:

Share with your peers how their choices for QA strategies could be used to supplement your own.

Write the head of a “while” loop that checks against the conditions that the user enters (declared as a variable userInput before the while loop head) The loop stops if the userInput is “exit” or the user does not enter anything. 

I have a transcript of a scenario for this project. Attached are the steps to follow.

Lab 4 – Lazy Deletion in BSTs
Parts A is required. Part B is optional and is worth two points extra credit (but must be submitted in addition to, and along with, Part A). Part C is optional but has no extra point value. Make sure you have read and understood
● both ​ modules A​ and ​ B​ this week, and
● module 2R – Lab Homework Requirements before submitting this assignment. Hand in only one program, please.
Part A (required) – Lazy Deletion With Ints
This will be your first foray into an actual ADT implementation. It is not a toy program, but the real deal. You’ll take the binary search tree implemented in the modules (and supplied in your downloaded header file libraries) and modify it to use lazy deletion rather than the explicit “hard deletion.”
You will find it helpful to fetch and install the files in the following zip archives now:
● https://fgamedia.org/faculty/anand/resources/CS_2C_Client_Support.zip
● https://fgamedia.org/faculty/anand/resources/CS_2C_Files.zip
If you have carefully studied and experimented with the binary search tree template class, this assignment should be “just right”. It is not as difficult as doing an ADT from scratch, which might require more than a week. Nonetheless, in the few methods that you must retool, you’ll find just enough of a challenge to feel like you are really cracking the problem. The changes and debugging you will be doing are typical of ADT design.
Preparation
Copy the file ​ FHsearch_tree.h ​ and name the copy ​ FHlazySearchTree.h​ . Work on the latter file for this assignment. In the new file, change the name of the classes FHsearch_tree​ and ​ FHs_treeNode​ to ​ FHlazySearchTree ​ and FHlazySearchTreeNode​ , respectively. ​ Hint: Do a global search/replace of the old names with the new ones in this file​ . Also, if you use ​ #ifndef/#define ​ at the top of the file (to avoid nested compilation) they should be changed to some name ​ distinct​ from FHSEARCHTREE_H​ .
This file should now compile without any errors and be compatible with your cs_1c library and project as a whole (other than the name of the new tree class). So far, you have basically duplicated the logic of a BST into a second class that behaves exactly like the first, but has a new name. This is your starting point.
New Class Design
1. Add a ​ bool deleted​ member to ​ FHlazySearchTreeNode​ . Adjust this class to accommodate this member.
2. Add a new ​ int mSizeHard​ member to the ​FHlazySearchTree ​ class which tracks the number of “hard” nodes in it, i.e., both ​ deleted​ and ​ undeleted​.
Meanwhile, ​ mSize​ is still there and will only reflect the number of ​ undeleted nodes. Normally, the client will not need to know about ​ mSizeHard​ , but we want it for debugging purposes. Give it an accessor, ​ sizeHard()​ , so the client can test the class by displaying both the soft size (the number the client normally wants) and the hard size.
3. Revise ​ remove()​ (recursive version) to implement ​ lazy deletion​ .
4. Adjust​ insert()​ ​ and any other methods​ that might need revision to work with this new deletion technique. This often means inspecting the ​ deleted member when you are traversing for the data and take appropriate action based on the value of ​ deleted​ . (The only exceptions to this is the
height​ -related members and methods which are only there for the derived class ​ AVL tree​ . You can ignore any ​height​ -related code you find in the ​ .h​ file.)
5. Add a public/private pair, void ​ collectGarbage()​ (the private method is the
recursive counterpart of the public one). This allows the client to truly remove
all deleted (stale) nodes. Don’t do this by creating a new tree and inserting
data into it, but by traversing the tree and doing a ​ hard remove​ on each
deleted node. This will require that you have a private ​ removeHard()​ utility
that works very much like our old ​ remove()​ method.
6. Test your code thoroughly.
I will help you with the testing by providing a sample ​ main()​ and successful run, but this
is not a thorough test of the class:
// Assignment #4 Instructor Solution
In addition to testing your client a little better than the above ​ main()​ does, add a couple of tests for​ findMin()​ and ​ findMax()​ at various stages (e.g., hard-empty tree, a tree that has non-deleted stuff in it, and a tree that is completely empty but has all soft-deleted nodes) to make sure your exception handling is working in​ findMin()​ and findMax()​ .
Option B – Lazy Deletion with EBooks (2 EC Points)
Apply the same new ​ ADT​ to ​ EBookEntry​ objects by reading them in and doing various
removes and inserts. Do garbage collection at various points.
Option C: Benchmarking
If you have time and interest, after completing the above program, try to formulate an experiment to see if the ​ lazy deletion​ helps or hinders various operations (insertions,
deletions, finds, etc.)
   Submission Instructions Again
It’s worth reiterating because many students find it hard to follow instructions the first time. If you’re not one of them, feel free to skip the below. Note the following very simple important instructions. I will
only accept and grade submissions that follow these guidelines except when they are specifically
overridden in instructions.
1. Your submission should be a plain text file. See above. Save your file as a plain text file.
2. It is insufficient to simply have plain text format. The file name SHOULD have a ​ .txt​ or .java​ extension. In the past, many students who submitted files with NO extension ended up
with no points earned for those assignments. I want to help you NOT be one of them. So that’s
why this guideline is explicitly stated here.
3. If you have multiple files you might otherwise need to submit, put them all in a single file, called
Assignment_N.txt and separate the various sections in this file using a commented line of
dashes. E.g. Your ​ Assignment_8.txt​ file could be:
4. IMPORTANT: Don’t include any provided files (e.g. iTunes*.*) in your submission (I already
have them 🙂
5. Submit your work ​ on time​ by uploading the above file into Canvas, well before the deadline.
6. The following guidelines are technically not mandatory, but following them would earn you the
full points you are eligible for. Why not earn easy-to-get points?
● Make sure you follow all the formatting guidelines. Serious points could be lost for badly
formatted or difficult-to-read code.
● Don’t over-engineer your code. Implement exactly what’s asked, no more and no less.
To demonstrate your additional knowledge, use the forums. Assignments are not the place to do it. No bells and whistles or decorative code/output.
● If you’re doing this course for a grade (i.e. your GPA is important) only attempt the BASIC OPTION unless you are absolutely certain you have the basics nailed.
Intermediate and Advanced options are generally graded far more strictly. You should, however, attempt the advanced options and post/discuss that code in the forums AFTER the lab has been graded.
● Make sure your output is not “touched up” by hand. Incorrect output is better than “doctored output.
