Search your Topic HERE.... Show sponsored links F riends, we have already discussed introduction and few more important topics of Data Base Management System. Today we shall discuss about the steps involved in the Database Design Process. The Data Base Design Process can be divided into six steps. The E-R Model is most relevant to the first three steps. Note : To make the concepts clear we shall try to understand the steps using a small example. Assume that you want to build a home. Now read the below steps by keeping this example in mind.

computer science Verified answer computer science The profit from the sale of a stock can be calculated as follows: $\text { Profit }=((N S \times S P)-S C)-((N S \times P P)+P C)$ where NS is the number of shares, SP is the sale price per share, SC is the sale commission paid, PP is the purchase price per share, and PC is the purchase commission paid. If the calculation yields a positive value, then the sale of the stock resulted in a profit. If the calculation yields a negative number, then the sale resulted in a loss. Write a function that accepts as arguments the number of shares, the purchase price per share, the purchase commission paid, the sale price per share, and the sale commission paid. The function should return the profit (or loss) from the sale of stock. Demonstrate the function in a program that asks the user to enter the necessary data and displays the amount of the profit or loss. Verified answer Recommended textbook solutions
