• Inventory ManagementObjectives: Use inheritance to create base and child classes Utilize multiple classes in the same program Perform standard input validation Implement a solution that uses polymorphismProblem:A small electronics company has hired you to write an application to manage their inventory. The company requested a role-based access control (RBAC) to increase the security around using the new application. The company also requested that the application menu must be flexible enough to allow adding new menu items to the menu with minimal changes. This includes re-ordering the menu items and making changes tothe description of a menu item without having to change the code.Security:The company has suggested to start the application by prompting the user for a username and password to authenticate the user. There are two types of users at this company, managers and employees. If managers log on to the application, they will seeall options on the menu list. If employees log on to the application, they will see a limitedset of options on the menu list. User information is stored in Users.dat file, which may ormay not exist at the start of the program. A super user “admin” with password “admin” has already been hardcoded in the program to allow for the initial setup and the creationof other users. The Users.dat file contains the FirstName, LastName, Username (case insensitive), HashedPassword and a flag to indicate whether a user is a manager or not.The file is comma separated and it is formatted as follows:Joe, Last, jlast, 58c536ed8facc2c2a293a18a48e3e120, trueSam, sone, 2c2a293a18a48e3e12058c536ed8facc, falseJane, Best, jbest, 293a18a48e3e12052058c536ed8facc2c, falseNote: Ensure that the ‘AddUser’ function does not add duplicate values, and the ‘ChangePassword’ function does not change password if username/password is entered incorrectly. If adding a new user or changing the password is successful, return true, or else return false.
• Application Menu:The menu of the application is dynamically loaded and displayed to the user only after the user successfully logs on. The menu items will be loaded from file “MenuList.dat”, which may or may not exist at the start of the application. If the file doesn’t exist, the application should show at least an Exit menu item as default. The file will contain all menu items details, including the name of the command that will be executed when the menu item is selected. If a menu item is marked as restricted (Boolean flag), only managers can see that item. The file contains the following comma separated fields, Description, a Boolean flag to indicate if the option is restricted to managers only, and the name of the menu command that will be executed when the option is chosen. The order and option number of a menu item may change depending on how they are listed in the file. The Exit option will always be listed last and it will not be in the file.Below is a sample of how the MenuList.dat file looks like:Add User, true, AddUserCommandDelete User, true, DeleteUserCommandChange Password, false, ChangePasswordCommandAdd New Product, true, AddProductCommandNote:The command name of each menu item must match the name of the class that you will create in the code (See AddProductCommand class in the code for example).Inventory:The inventory consists of multiple products of type Product stored in class ProductCatalog. The ProductCatalog is responsible of all inventory operations that add, remove, find and update a product. When printing a product information, the product retail price should be calculated and displayed as well. Retail price = (cost + (margin * cost/100)). A list of functions has been added to this class in the provided code template. You must implement all listed functions. The inventory products will be saved in file Inventory.dat, which may or may not exist when the program first starts. The file will contain the product unique id (int), product name (string), cost (double), quantity (int)and margin (int, integer that represents margin percentage).The Inventory.dat file is comma separated and formatted as follows:3424, Smart Watch, 20.45, 23, 8065454, Flat Screen TV, 465.98, 15, 35435, Computer Monitor, 123.54, 84, 43Program Flow: Program starts in main() method Prompt user for username and password Authenticate user and maintain the logged-on user object Load inventory

Pay special attention to Figure 8.1 and Figure 8.2. Note how the corporate CIO should engage with each of the regional leaders. Why is this important? 

Access Controls Procedure Guide 

Scenario 

Changing access controls can have some undesirable effects. Therefore, it is important to carefully consider changes before making them and provide mechanisms to reverse changes if they have unexpected consequences. 

Always Fresh management has asked you to develop procedures for changing any access controls. The purpose of these procedures is to ensure that staff: 

▪ Understand and document the purpose of each access control change request
▪ Know what access controls were in place before any changes
▪ Get an approval of change by management
▪ Understand the scope of the change, both with respect to users, computers, and objects ▪ Have evaluated the expected impact of the change 

▪ Know how to evaluate whether the change meets the goals 

▪ Understand how to undo any change if necessary 

Tasks 

Create a guide that security personnel will use that includes procedures for implementing an access control change. 

The procedure guide must contain the steps Always Fresh security personnel should take to evaluate and implement an access control change. You can assume any change requests you receive are approved. Ensure that your procedures include the following: 

▪ Status or setting prior to any change 

▪ Reason for the change
▪ Change to implement
▪ Scope of the change 

▪ Impact of the change
▪ Status or setting after the change 

▪ Process to evaluate the change 

Required Resources 

▪ Internet access 

▪ Course textbook 

Submission Requirements 

▪ Format: Microsoft Word (or compatible)
▪ Font: Arial, size 12, double-space
▪ APA Citation Style

According to Kirk (2016), most of your time will be spent working with your data.  The four following group actions were mentioned by Kirk (2016):
Data acquisition: Gathering the raw materialData examination: Identifying physical properties and meaningData transformation: Enhancing your data through modification and consolidationData exploration: Using exploratory analysis and research techniques to learnSelect 1 data action and elaborate on the actions performed in that action group.

Remember your initial post on the main topic should be posted by Thursday 11:59 PM (EST). Your 3 following posts should be commenting on your classmates’ post on different days by Sunday 11:59 PM (EST). You should end the week with 4 total discussion posts.
A quality post is more than stating, “I agree with you.” Maybe you should state why you agree with

You must do the following:

1) Create a new thread to write your initial response to the discussion prompt.

2) Select AT LEAST 2 other students’ threads and post substantive comments on those threads. Your comments should extend the conversation started with the thread.

3) Provide a thoughtful research-based response and include references to support your thoughts.

4) Exclude attachments and cover page in your submission. Type your response in the message box. When responding to your peer, address your peer by name.

 5) ALL original posts ( two to three paragraphs supported by resources) and comments must be substantive. (I’m looking for about a paragraph – not just “I agree.”)

6) Paraphrase text from resources used and cite. If quoting text, use double-quotes and cite.

Graduation Party Location

It is now time to revisit your graduation planning activities by  choosing your location and entertainment for the party. You will do this  by creating tables to compare the attributes and issues of your various  choices.

Click on the link below, Week 2 Project Tips, for some visual aids on how to tackle this week’s project.

Week 2 Project Tips

Create a new Microsoft Word document and save it as W2P_LastName.docx. Note that you might want to change your page orientation to landscape to better fit your data.

1. Create a table to compare the different locations you chose in Week 1.  You can add a table to your document by using the Table icon in the  Insert ribbon of Microsoft Word. Your table should include the following  columns – you can see an example of this layout in the Week 2 Project Tips:
   • Location: List the three possible locations.
   • Web site: Include the URL hyperlink for each location’s Web site.
   • Positives: Include a bulleted or numbered list* of positive attributes of each.
   • Negatives: Include a bulleted or numbered list of issues for each location.
   • Estimated Cost: Include the cost(s) associated with using the location/facility.
     *You  can create a list using the icons in the Paragraph panel of the Home  ribbon (Bullets, Numbering, or Multilevel). Changing the margin settings  of the cells with bullets can be helpful.
2. Beneath your table, write a paragraph of at least 50 words to include:
   • Identify which location you chose.
   • Justify why you made the choices you did using the information in the tables to guide your decision.
   • Check the Status bar at the bottom of the window to see the word count.
      
3. Finally add the finishing touches to the paper.
   • Add page numbers in the Footer (bottom of your page).
   • Add a Header that includes the name of your event and your name.
   • Add some formatting and color to your table.
   • Bold and center the table headings.
   • You can change the color of your text or the color of the background  to color code your table or make it more readable. Be creative and have  fun!

By the due date assigned, submit your completed document to the Submissions Area. In the Comments box, briefly share your experiences with completing this project.
