In this module, you learned about multiple forms in C#. You will be completing one program for this module.

Create an application named as M11 Assignment_YourLastname which has multiple form order program for customers of Fresh Produce Store.

You pick the controls that would work best and what your forms look like, but your program should meet the following objectives:

NOTE: All controls and variables should be correctly named using the naming standards indicated in the text.

• Have a graphic that you think represents Frech Produce Store.
• Allow customers the option of choosing tomatoes ($1.91 per pound), peppers ($2.32 per pound), onions ($1.05per pound) and potatoes($1.50 per pound). 
• The customer enters a weight for each one selected in pounds in a box. Use either a numeric Up-down or Textbox. If using a Textbox, you will need to validate the value entered to make sure its numeric.
• Exit Button – On main Form 
• Order Now Button – On main form
• Close Button – On second form
• After the customer clicks an Order Now button, display the price of the order on the second form.

Assignment Content

1. In Week 1, you discussed GIG, Inc.’s benefits and concerns with moving to the cloud. In Week 2, you created a high-level diagram of a system using built-in AWS that provided reliability, availability, and continuity across the migrated environment. Last week, you chose a database and created a diagram that visualized the chosen system and implementation steps.
   This week, you will create a Microsoft® Excel® spreadsheet and provide a summary for the critical IAM structure provided below. This will be used for all systems and ensure all users have only the privileges needed for their job.
   The company has three levels of access:
   • Customer (Minimal-web only)
   • Administrative (Implementation-access to Cloud environment at a programmatic level and operational level)
   • System (The requirement(s) for system to system access)
   • The company security compliance controls need to ensure that each level of access is only allowed to authorized users/systems.
     Create a Microsoft® Excel® spreadsheet matrix listing all applicable information for each level of access, and ensure you include this information:
   • AWS that provide access control (network access control list, domain name service, security groups, etc.)
   • Types of restrictions (port, protocols, etc.)
   • The specific implementation matrix for each level (security groups will only allow port 22 to this level)
   • A basic set of IAM users, groups, and roles
   • Write a 1-page summary in Microsoft® Word about the structures and security benefits.
     Submit your spreadsheet and summary.

Steganography, as defined by Webster’s Dictionary, is the art or practice of concealing a message, image, or file within another message, image, or file.  For this week’s assignment we are going to work with arrays, strings, and StringBuilder to decode a message that has been hidden inside another file and sent to us from our friend, Randy Waterhouse (you have my sincere admiration if you get that reference!).  Randy is sending us a message that he has encoded within a regular data file.  This means he has taken the file and changed random characters within that file that will spell out a message if we can figure out which characters he changed and the ordered in which he changed them. 

The original file looked like this:

Randy then went line by line and changed certain characters according to the below table.  The lines and columns of the table are indexed starting at zero, just like our arrays in C#.  The first entry in the table, “0,5=n” means that Randy changed the character in line zero at the 5th letter (which is actually the 6th since we started at zero) to be “n” (it was originally “W”).  Here is the table of changes that Randy made.  Note that he only changed 5 characters per line and that each line has 60 characters in it:

And here is the new data with Randy’s changes:

If we know the order that he changed the characters in each line, we can create the following four strings of five characters each:

If we append all those strings together from top to bottom, we will have the full message that Randy sent us (apparently Randy is a fan of the movie “A Christmas Story”):

Drink more Ovaltine!

So how do we figure out the order?  Many cryptographic systems have two main components: an equation and a key.  The equation generates a string of numbers based on the key number that is plugged in to that equation (that’s a super-simple explanation, but this isn’t a crypto class, so…).  In this case, Randy kept it simple.  He’s a C# programmer, after all!  He used the Random class as his equation, and he knows that using a certain number as a “seed” or “key” will make Random generate the same sequence of numbers when “next” is called.  If Randy tells you the seed, and you know that he did his encryption line by line, then you can get the characters from Randy’s seemingly random data and generate the message.

Your Assignment:

The attached assignment shell has an array of 22 strings already declared for you that represent the lines in a data file.  Each line has 60 characters in it, but Randy only changed 5 of those characters.  You need to use nested for loops (i.e. one for loop inside another) and Random’s “next” method to pull the five characters from each line and store those in a different array of strings, where each string is 5 characters long.  Remember, if you seed your Random with the same number Randy did, then your “next” will generate the same sequence of numbers.  Those numbers are the indices of the characters you need to get from each line.  Once you have put the five characters from each line into your array, you need to call your printIt method.  Your printIt method should take the array of decrypted characters as input.  It should first print the contents of that array to the screen (there should be 22 lines of 5 characters each).  Then it should use a StringBuilder to put those 22 lines together into something that is more readable.  DO NOT simply  “+=” each of the 22 strings into a larger string.  You must use StringBuilder.  Finally, print the contents of your StringBuilder to the screen – you should see the message that Randy hid in the data file. For full credit, you must also include the message as part of your submission text for this assignment! 

You need to seed your random number generator with 243 because that’s the number Randy used when encrypting his message (he chose that because 243 would generate 22 5-character sequences where those 5 characters would not repeat).

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 material
• Data examination: Identifying physical properties and meaning
• Data transformation: Enhancing your data through modification and consolidation
• Data exploration: Using exploratory analysis and research techniques to learn

Select 1 data action and elaborate on the actions preformed in that action group.

1. Obtain one of the data sets available at the UCI Machine Learning Repository and apply as many of the different visualization techniques described in the chapter as possible. The bibliographic notes and book Web site provide pointers to visualization software.

2. Identify at least two advantages and two disadvantages of using color to visually represent information.

1. What      are the arrangement issues that arise with respect      to three-dimensional plots?
2. Discuss      the advantages and disadvantages of using sampling to reduce the number of      data objects that need to be displayed. Would simple random sampling (without      replacement) be a good approach to sampling? Why or why not?
3. Describe      how you would create visualizations to display information that de-scribes      the following types of systems.

a) Computer networks. Be sure to include both the static aspects of the network, such as connectivity, and the dynamic aspects, such as traffic.

b) The distribution of specific plant and animal species around the world fora specific moment in time.

c) The use of computer resources, such as processor time, main memory, and disk, for a set of benchmark database programs.

d) The change in occupation of workers in a particular country over the last thirty years. Assume that you have yearly information about each person that also includes gender and level of education. 

Be sure to address the following issues:

· Representation. How will you map objects, attributes, and relation-ships to visual elements?

· Arrangement. Are there any special considerations that need to be taken into account with respect to how visual elements are displayed? Specific examples might be the choice of viewpoint, the use of transparency, or the separation of certain groups of objects.

· Selection. How will you handle a large number of attributes and data objects

6. Describe one advantage and one disadvantage of a stem and leaf plot with respect to a standard histogram.

7. How might you address the problem that a histogram depends on the number and location of the bins?

8. Describe how a box plot can give information about whether the value of an attribute is symmetrically distributed. What can you say about the symmetry of the distributions of the attributes shown in Figure 3.11?

9. Compare sepal length, sepal width, petal length, and petal width, using Figure3.12.

10. Comment on the use of a box plot to explore a data set with four attributes: age, weight, height, and income.

11. Give a possible explanation as to why most of the values of petal length and width fall in the buckets along the diagonal in Figure 3.9.

12. Use Figures 3.14 and 3.15 to identify a characteristic shared by the petal width and petal length attributes.

13. Simple line plots, such as that displayed in Figure 2.12 on page 56, which shows two time series, can be used to effectively display high-dimensional data. For example, in Figure 2.12 it is easy to tell that the frequencies of the two time series are different. What characteristic of time series allows the effective visualization of high-dimensional data?

14. Describe the types of situations that produce sparse or dense data cubes. Illustrate with examples other than those used in the book.

15. How might you extend the notion of multidimensional data analysis so that the target variable is a qualitative variable? In other words, what sorts of summary statistics or data visualizations would be of interest?

16. Construct a data cube from Table 3.14. Is this a dense or sparse data cube? If it is sparse, identify the cells that are empty.

17. Discuss the differences between dimensionality reduction based on aggregation and dimensionality reduction based on techniques such as PCA and SVD.
