The data warehouse is one of the most important business intelligence tools a business needs to have. It turns the massive amount of data generated from multiple sources into a format that is easy to understand.

Discuss the data warehouse concept?

JAVA CODE

Using the PurchaseDemo program and output from the previous problem as your guide, write a program that uses the Purchase class to set the following prices, and buy the number of items as indicated. Calculate the subtotals and total bill called total. Using the writeOutput() method display the subtotals as they are generated as in the PurchaseDemo program. Then print the total bill at the end. You may use integer, double, and String variables as needed but you may use only one object of the Purchase class and a for loop.

(Use the readInput() method for the following input data, you may assume the prompts and Scanner for the readInput() method takes place but you need not include either in your program output. )

Oranges: 10 for 2.99 buy 2 dozen oranges

Eggs; 12 for 1.69 buy 3 dozen eggs

Apples: 3 for 1.00 buy 20 apples

Watermelons: 4.39 each buy 2 watermelons

Bagels; 6 for 3.50 buy 1 dozen bagels

Organizations need to know the value of their data to find the best way to protect it. The data must be categorized according to the organization’s level of concern for confidentiality, integrity, and availability. The potential impact on assets and operations should be known in case data, systems, and/or networks are compromised (through unauthorized access, use, disclosure, disruption, modification, or destruction).

Choose an organization from the Health Care, Finance, or Education sector to study throughout this course.

Based on your chosen organization, ensure you:

• Discuss the organization’s data.
• Discuss the organization’s categorization of the data based on the Standards for Security Categorization of Federal Information and Information Systems.

A regional transit company wants to determine whether there is a relationship between the age of a bus and the annual maintenance cost. A sample of 10 buses resulted in the following data: spss

Instructions:

1. Input the data into an SPSS work sheet making sure that all your variables are labelled appropriately
2. Create a scatter plot for these data.
3. What does the scatter plot indicate about the relationship between the age of a bus and its annual maintenance costs?
4. What is the correlation coefficient between the age of a bus and annual maintenance cost?
5. Estimate a regression model that could be used to predict the annual maintenance cost given the age of the bus.
6. What is the equation of the estimated model?
7. Test whether each of the regression parameters β₀ and β₁ is equal to zero at the 0.05 level of significance testing.
8. What is the correct interpretations of these parameters?
9. How much of the variation in the sample values of annual maintenance costs does the regression model you estimated explain?
10. What do you predict the annual maintenance cost to be for a 4.5 year old bus?
11. Save all your commands to a syntax file

Let Ajay and Bijay public key is certified by a CA. Both of them uses secure DHKE with parameters α and p for encrypting/decrypting messages with a symmetric algorithm such as AES. Now assume Ranjit hold the CA’s signature algorithm (and especially its private key), which was used to generate certificates. Can Ranjit decrypt old cipher-texts which were exchanged between Ajay and Bijay before the CA signature algorithm and private key was compromised, which Ranjit had stored? Explain.
