Question-1

[50 marks]

The purpose of this question is to develop a web page that prompts the user to enter three values about an isosceles triangle, the left coordinates of its base, the length of its base and the triangle height. Then the web page calculates the right coordinates of its base, the coordinates of the triangle vertexand the length of the equal sides.

Hint: You can consider that the base of the isosceles triangle is always parallel to x-axis (horizontal base).

The web page should be implemented by using only the basic HTML tags and PHP codes that you learnt in this course. The final code with 2 snapshots should be provided in your answer sheet.

The designed web page should include a title, a header, an input form for entering the required values and an output form for presenting the calculated values or a suitable message when some violations are occurred. The design and the layout of the web page are left intentionally for the student to distinguish his/her TMA form other students and to show his/her creativity in designing the web page.

The PHP part should include at least two PHP function for computing the coordinates of the triangle vertices and length of the triangle sides.

Question-2

[20 marks]

Blood Bank Management Information System (BBMIS) is a database management system that provides blood to the patients who need blood. BBMIS keeps some records about blood donations that facilitate the searching for a certain blood group.

In this regard, you are asked to do some research about BBMIS, select one of the aspects that managed by BBMIS and then design two database tables about this aspect [14 marks] and another database table that represents a relation between the previous two tables [6 marks]. For each table you need to:

1- Define the objective(s) of the table.

2- Design at least five fields for the table; data type and size.

3- Determine the primary key of the table.

Answer

· Donor table: to store and retrieve the donor information as id, first name, last name, date of birth and blood group.

· Patient table: to store the patient information as patient ID, first name, last name, date of birth and blood group.

· Blood table: To store the donated bloods from donors and to store any patient who took blood. The information are blood id, patient id, donor id, blood group and expire date.

Question-3

[30 marks]

A new company is planning to build a new database system for holding information about Railway Reservation System (RSS). ‘Passengers’, ‘Train Tickets’, and ‘Reservations’ are part of the information that the new company wants to store in the new database. These tables are shown below in figure 1, figure 2 and figure 3. The new company intends to use MySQL for building the new database.

Passenger ID	Passenger Name	Passenger Age	Passenger Gender
824	Ahmad	56	Male
