Kathryn Avery has been a Database Administrator (DBA) with a nationwide retail chain (Big Chain) for the past 6 years. She has recently been asked to lead the development of Big Chain’s first data warehouse. The project has the sponsorship of senior management and the Chief Information Officer (CIO). The rationale for developing the data warehouse is to advance the reporting systems, particularly in sales and marketing and, in the longer term, to improve Big Chain’s Customer Relationship Management (CRM) system. Kathryn has been to a Data Warehousing Institute conference and has been doing some reading, but she is still mystified about data warehouse development methodologies. She knows there are two groups—EDW (Inmon) and architected DMs (Kimball)— that have equally robust features. Initially, she believed that the two methodologies were extremely dissimilar, but as she has examined them more carefully, she isn’t so certain. Kathryn has a number of questions that she would like answered:

a. What are the real differences between the methodologies?
b. What factors are important in selecting a particular methodology?
c. What should be her next steps in thinking about a methodology?

Consider the following function main: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . } a. write the definition of the function inputarray that prompts the user to input 20 numbers and stores the numbers into alpha. b. write the definition of the function doublearray that initializes the elements of beta to two times the corresponding elements in alpha. make sure that you prevent the function from modifying the elements of alpha. c. write the definition of the function copyalphabeta that stores alpha into the first five rows of matrix and beta into the last five rows of matrix. make sure that you prevent the function from modifying the elements of alpha and beta. d. write the definition of the function printarray that prints any onedimensional array of type int. print 15 elements per line. e. write a c11 program that tests the function main and the functions discussed in parts a through d. (add additional functions, such as printing a two-dimensional array, as needed.)
