QUESTION 1

 Given the following business scenario, create a Crow’s Foot ERD using a specialization hierarchy if appropriate. Two-Bit Drilling Company keeps information on employees and their insurance dependents. Each employee has an employee number, name, date of hire, and title. If an employee is an inspector, then the date of certification and certification renewal date should also be recorded in the system. For all employees, the Social Security number and dependent names should be kept. All dependents must be associated with one and only one employee. Some employees will not have dependents, while others will have many dependents.

QUESTION 2

 Given the following business scenario, create a Crow’s Foot ERD using a specialization hierarchy if appropriate. Tiny Hospital keeps information on patients and hospital rooms. The system assigns each patient a patient ID number. In addition, the patient’s name and date of birth are recorded. Some patients are resident patients who spend at least one night in the hospital, and others are outpatients who are treated and released. Resident patients are assigned to a room. Each room is identified by a room number. The system also stores the room type (private or semiprivate) and room fee. Over time, each room will have many patients. Each resident patient will stay in only one room. Every room must have had a patient, and every resident patient must have a room.

QUESTION 3

 Given the following business scenario, create a Crow’s Foot ERD using a specialization hierarchy if appropriate. Granite Sales Company keeps information on employees and the departments in which they work. For each department, the department name, internal mail box number, and office phone extension are kept. A department can have many assigned employees, and each employee is assigned to only one department. Employees can be salaried, hourly, or work on contract. All employees are assigned an employee number, which is kept along with the employee’s name and address. For hourly employees, hourly wages and target weekly work hours are stored; for example, the company may target 40 hours/week for some employees, 32 for others, and 20 for others. Some salaried employees are salespeople who can earn a commission in addition to their base salary. For all salaried employees, the yearly salary amount is recorded in the system. For salespeople, their commission percentage on sales and commission percentage on profit are stored in the system. For example, John is a salesperson with a base salary of $50,000 per year plus a 2 percent commission on the sales price for all sales he makes, plus another 5 percent of the profit on each of those sales. For contract employees, the beginning date and end date of their contracts are stored along with the billing rate for their hours.

QUESTION 4

Modify the design shown in Figure 4.35 to include these business rules:

• An employee could be staff, a professor, or an administrator.
• A professor may also be an administrator.
• Staff employees have a work-level classification, such as Level I or Level II.
• Only professors can chair a department. A department is chaired by only one professor.
• Only professors can serve as the dean of a college. Each of the university’s colleges is served by one dean.
• A professor can teach many classes.
• Administrators have a position title.

Given that information, create the complete ERD that contains all primary keys, foreign keys, and main attributes.

QUESTION 5

 Tiny College wants to keep track of the history of all its administrative appointments, including dates of appointment and dates of termination. (Hint: Time- variant data is at work.) The Tiny College chancellor may want to know how many deans worked in the College of Business between January 1, 1960, and January 1, 2018, or who the dean of the College of Education was in 1990. Given that information, create the complete ERD that contains all primary keys, foreign keys, and main attributes.

QUESTION 6

 Some Tiny College staff employees are information technology (IT) personnel. Some IT personnel provide technology support for academic programs, some provide technology infrastructure support, and some provide support for both. IT personnel are not professors; they are required to take periodic training to retain their technical expertise. Tiny College tracks all IT personnel training by date, type, and results (completed versus not completed). Given that information, create the complete ERD that contains all primary keys, foreign keys, and main attributes.

QUESTION 7

The FlyRight Aircraft Maintenance (FRAM) division of the FlyRight Company (FRC) performs all maintenance for FRC’s aircraft. Produce a data model segment that reflects the following business rules:

• All mechanics are FRC employees. Not all employees are mechanics.
• Some mechanics are specialized in engine (EN) maintenance. Others are specialized in airframe (AF) maintenance or avionics (AV) maintenance. (Avionics are the electronic components of an aircraft that are used in communication and navigation.) All mechanics take periodic refresher courses to stay current in their areas of expertise. FRC tracks all courses taken by each mechanic—date, course type, certification (Y/N), and performance.
• FRC keeps an employment history of all mechanics. The history includes the date hired, date promoted, and date terminated. Given those requirements, create the Crow’s Foot ERD segment.

I have attached the hw3 template. I need it soonest possible.

A prefix expression is one where each operator appears before its two operands.  For example the fully parenthesized infix expression ( ( ( a + b) / (c+d) ) * (e / f) ) becomes the prefix expression  *  /  +  a  b  +  c  d  /  e  f.  The object of this assignment is to write a program to convert a fully parenthesized infix expression to its equivalent prefix expression. Assume the input infix expressions consist only of variables a through z, operators +,  -,  *, /   and parentheses ‘(‘, ‘)’ .  Use the following algorithm:

(1) Create three stacks of characters: stk1, stk2, stk3.

(2) Read the input infix expression one character at a time and push every character read ( other than ‘)’  ) onto stk1. Do not push the character read if it is ‘)’.

(3)  As long as stk1 is not empty, do the following:

           Fetch the top character ( call it c ) of stk1 and pop stk1.

           if c is an alphabetic character (a-z),  push it onto stk3. (You can use the function islower(c) to test if character is one of a-z.)

           if c is an operator,  push it onto stk2.

           if c is ‘(‘ then fetch the top character of stk2, push it onto stk3, and pop stk2.

(4)  Print stk3 top to bottom by repeatedly fetching the top of stk3, printing it, and popping stk3, until stk3 is empty.

There is starter code in folder Hwk3 in your course folder on comsci.  Open the project file Hwk3.cbp in codeblocks and complete the program hw3.cpp in that project.

The program uses the class template stack from the standard C++ library. Check the examples on the slides for how to push, pop, and check for empty stack.
