- In the hierarchy of data, what is the difference between a data attribute and a data item? What is the domain of an attribute?arrow_forwardA learning company wants to set up its database. They are trying to keep track of the following: student ID, name, grade level, the subject they need help in, and their contact and payment information. They also want to keep track of the teacher’ information such as their ID, name, subject matter expertise, and times available and rate. They will like to keep track of which student is assigned to which teacher and their meeting schedule as well.

The purpose of developing the database is keep the staff information such as staff identity number, staff name, staff address, staff telephone number, staff job title and staff salary. As for the staff telephone number, the database allows keeping more than one of the staff telephone numbers. For the department information, the database keeps the name of the department and its location. It is required that every staff belongs to at least one department. Also, it is required that each department has exactly one staff to lead the department. To improve staff self-development, the university encourages every staff to attend courses. Hence, the database keeps the course information such as the course name, course duration, and course cost. Each staff is required to attend at least one course. For one course, the university can approve a number of staff…arrow_forward
- Design the database, following an ER model. 1. Patients: Patients are tracked by a unique patient ID. Personal information includes first name, last name, phone number, Date of Birth, and sex. The combination of the Patient's first and last name must be unique. Patient's sex is a mandatory field. Patient can be registered at any clinic. 2. Cancer: Type of cancer is tracked by a unique ID. Cancer is categorized as either Oral, Lung, Breast, Liver, Blood, Bone, Pancreatic, Cervical, or Prostrate. Stage of cancer can be Stage I, Stage II, or Stage III Stage of cancer detection. Treatment given: Chemotherapy only, Surgery with chemotherapy, Surgery only or Radiation therapy. Patient_id is an FK which references the ID of the Patient. Clinic_id is an FK which references the ID of the Clinic that patient register. Patient information must be stored at one clinic. Patient Date of detection of Cancer. 3.

- A Professor wants a database for his new University that will maintain data for the following entities with their attributes: a. Courses: title, credits, syllabus and prerequisites b. Course offered: course ID, year, semester, section number, instructor(s), timings and classroom. c. Students: student_ID, name and program d. Instructors: Instructors_ID, name, department and title They require a proper model to help with the enrolment of students into courses and rightfully graded after the course is rolled out.

Document all assumptions that you make about the mapping constraints.arrow_forwardNOTE: please explain better . Question 4 You have just been hired as a consultant for a big Health Care provider. Impressed by your background in databases, they want you to completely redesign their database system. Talking with the people at the HC provider, you get the following information (be very careful on some of these attributes, and apply everything you have learned to this point: - The database contains information about patients, hospitals and doctors. - Each patient has an ID, first name, last name, address and age. A patient is uniquely identified by his or her ID. - Each hospital has an id, name and budget. The id uniquely identifies a hospital. - Each doctor an id, a full name, email address and a favorite movie.
