Data Modelling is the primary step in the process of database design. Compare and contrast Conceptual data model versus Physical data model. Illustrates with help of example to list down data (entities), relationship among data and constraints on data.

Section A. Declare and initialize an array myChars containing the following characters: B, C, D, A, M, S and F.Remember to choose the correct data type for the array elements.Section B. Using a WHILE loop, output the elements of the array myChars so that they are displayed on thesame line and separated by a space. Use .length to get the length of the array.Section C. Change the last value of the array myChars to the letter X. Use .length in your code.Section D. Using a FOR loop, output the elements of the myChars array so that they are displayed on the sameline and separated by a dash (an extra dash at the end is okay). Use .length in your code.Section E. Declare an array of int of capacity 10 named thisArray.Section F. Use a FOR loop to populate the array thisArray with the following numbers 5, 10, 15, 20, 25. Thinkof a way to insert these numbers without actually writing “5” or “10” and so on, but by using the variable i ofyour FOR loop. NOTE that this is a partially-filled array and…

What is the cartesian product of sets {6,7} and {7,8,9}?

implement program to creates an array named sales (tracking one week of sales for two months), assigns salesfigures to its elements, and then loops through the array to calculate the average sales for one week of each of the two months stored in the array.
