Assume you are part of the systems development team at a medium-sized organization. The database will enable sales reps to have more control over their customer information including up to date information on purchases, backorders, returns, and invoices. As a result of the system the company will be able to assign accounts to sales reps based on their expertise, the proximity to their other accounts, and experience level in the company. Commissions will also vary based on the types of products and services sold and the reps will be able to see special promotional programs in their regions. Part 1: you have just completed the database design portion of the systems design phase, and the project sponsor would like a status update. Assuming the project sponsor is a VP in the marketing department, with only a high-level understanding of technical subjects, how would you go about presenting the database design you have just completed? Part 2: how would your presentation approach change if the project sponsor were the manager of the database team? Somebody please answer fast

We as humans write math expression in infix notation, e. g. 5 + 2 (the operators are written in-between the operands). in a computer’s language, however, it is preferred to have the operators on the right side of the operands, i. e. 5 2 +. for more complex expressions that include parenthesis and multiple operators, a compiler has to convert the expression into postfix first and then evaluate the resulting postfix. write a program that takes an “infix” expression as input, uses stacks to convert it into postfix expression, and finally evaluates it. it must support the following operations: + - / * ^ % (example infix expression: (7 - 3) / (2 + 2)postfix expression: 7 3 - 2 2 + /result: 1guidelines: 1. you will need to use stacks in three placesa. one for the parenthesis check [char stack]b. one during infix to postfix [char stack]c. one during evaluation [int stack]for a and b above, you can use same array and same push, pop method as both ofthem are char. but for evaluation you have int stack and you might consider to createanother push pop method to handle it. maybe push_int, pop_int, etc. or find otherstrategy to utilize existing push pop method2. you can create a function for obtaining operator priority. that function should take anoperator as input and return its priority as an integer. this function will you a lot andreduce repeated code3. during evaluation you will need to convert char into integer. example for single digit: char c = '5'; int x = c - '0';
