Suppose that you are the data analyst on the project team building a data warehouse for an insurance company. List at least three data sources from which you will bring the data into your data warehouse?
A. Explain how cryptographic mechanisms can be used to guarantee the following basic security services. a. Confidentiality b. Authentication c. Integrity d. Non-repudiation e. Non-replay
The difference between the representation of a decision structure and a loop in a flowchart.
b) Sir Richards of Bishop Herman College has taught his students quadrilaterals. He explained that trapezium is an example of a quadrilateral. You are an intern at the school. Teacher Ziggy has asked you to write a generic C++ program that will enable students to calculate the area and volume of a trapezium. The program should prompt a student to enter the values for the length of the parallel sides and is perpendicular distance between the parallel sides respectively. The program should calculate and display the area and volume of the trapezium. The program should allow a student to try other values for the length of parallel sides and is perpendicular distance between the parallel sides without exiting the program.
Write a program to using the principle of control structures (if /else statements) determine which the students grade, based on the marks numbers entered by the user (Using the table below). (10pts)
