• 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

 Do you feel that countries and companies need explicit strategies for technology development, given the tremendous amount of largely spontaneous creativity that occurs today, often in areas where new technologies are not expected to exert a great influence.  Why or why not? 

• Explain, define, or analyze the topic in detail

 Do you foresee that the traditional computer will be replaced by mobile and smart technologies as a primary device form factor in the near future? If one looks at the world of education for example, the use of Google Chromebooks and Apple iPads are now running the majority of school infrastructures. Mobile apps replace traditional software. Can the same hold true for corporate enterprises today? 

Write an essay of at least 500 words discussing the reasons for the two new auditing roles in Oracle 12c. Why did Oracle consider them necessary? What problems do they solve? How do they benefit companies?

Discussion Topic

Choose a TCP/IP service, such as a web  browser, email, file transfer, remote shell, DHCP, DNS, network time  protocol, network address translation, etc. 

  Important!

• Everyone should pick a different service, if possible, to keep the discussion fresh.

In your original post, answer the following about the service you have chosen:

• How would you determine the IP addresses of your devices on your network?

 Success Hints

You can use ipconfig if you use the command line.

You can use whatismyipaddress.com if you have connectivity on your devices. 

• Using Google, determine how to look up your IP address in the Windows 10 GUI.
• How would you determine if your devices are able to communicate on your network?

 Success Hint

You can use ping on your computers. How would you do it on your mobile devices?)

• Using ipconfig, how do you determine the IP address of your home router?
• Trace a request and a response with the help of a diagram of the TCP/IP service that you chose.
• Follow the request and response through each of the TCP/IP layers.
• Describe what happens at each layer of the OSI and TCP/IP reference models. 

The final portfolio project is a three-part activity. You will respond to three separate prompts but prepare your paper as one research paper. Be sure to include at least one UC library source per prompt, in addition to your textbook (which means you’ll have at least 4 sources cited). 

Start your paper with an introductory paragraph.

Prompt 1 “Blockchain” (2-3 pages): Explain the major components of a blockchain. Be sure to include how blockchain is affecting a global economy and how you see it growing in the future. 

Prompt 2 “Big Data” (1-2 pages): Describe your understanding of big data and give an example of how you’ve seen big data used either personally or professionally. In your view, what demands is big data placing on organizations and data management technology?  How does big data affect a global economy.

Prompt 3 “Government and Policies” (1-2 pages):  Discuss the role government plays in a global economy.  Also, look at what policies are currently in place and then discussion what policies should be put in place..

Conclude your paper with a detailed conclusion section. 

The paper needs to be approximately 6 pages long, including both a title page and a references page (for a total of eight to ten pages). Be sure to use proper APA formatting and citations to avoid plagiarism.

Your paper should meet these requirements: 

• Be approximately six to eight pages in length, not including the required cover page and reference page.
