Q1. Draw an E-R Diagram for the following situation. At the university system each STUDENT must be assigned an ADVISOR who counsels students about degree requirements and helps students register for classes (COURSE). Each student must register (REGISTRATION) for classes with the help of an advisor, but if the student's assigned advisor is not available, the students may register with any advisor, We must keep track of students, the assigned advisor for each, and the name of the advisor with whom the students registered for the current term. Tips: Attributes of STUDENT include Student ID (the identifier), Name, and Major. Attributes of ADVISOR include Advisor ID (the identifier), Name, and Department. Attributes of COURSE include Course ID (the identifier), Title, and Credits. Attributes of REGISTRATION include Semester, and Year. Based on your background, think of logical and standard relationships between the given entities.

PLZ help with the following: Create a Crow’s Foot ERD. Draw YOUR entity relationship diagram (ERD) to indicate entities, relationships, connectives, and resolve M:N relationships. For the following: The faculty and students (we refer to them in our system as clients) can electronically check out any book at any time. A book must have at least one author but can have more authors. An author must have written at least one book or more to be included in the system. A book may have neverbeen checked out, but can be checked out many times by the same client or different clients over time. A client may have never checked out a book or they may have checked out many books over time. To simplify determining which client currently has a given book checked out, a M:N relationship between BOOK and CLIENT should be maintained. The information recorded for each book is book number, book title, book subject, and year of publication. For each author, the library records the author ID,…
Quiz-2 Section C 1. What is the purpose of activity diagram? Give a situation where you should use the forking concept. [4] 2. Draw an activity diagram for the following case [16] A swimline diagram for the following scenario to withdraw money from an ATM. Use only this description (do not make up your own information!). The customer inserts the ATM card and then enters their pin number. The Bank system then validates the pin. If the pin is invalid, the ATM machine ejects the card, the customer takes the card, and the scenario ends. Assuming the card pin was valid, the customer enters an amount to withdraw. The bank checks the account balance. If the balance is less than the amount to withdraw, the ATM shows the balance, and then ejects the card. Once ejected the customer then takes the card and the scenario ends. Assuming the amount is available, the customer takes money from the slot and at THE SAME TIME the bank debits the account. Once the customer has taken money and the account…
Draw clearly from existing scenario text the Entity Relationship Diagram (ERD) “There is a group of employees who have run the website. Three admins are responsible to check registration forms filled by babysitters. An accountant is responsible to check fees payments. All these employees are supervised by the manager. Each babysitter can register on the website one time by filling in her data including first and last names, qualifications, fee rate per hour (25 SAR per Hour), contact information, address, photo, and years of experience. The system will issue for her id and registration date. Mothers can make booking as many as they need. For each time, they must fill in their names, contact information, address, number of children, the date and time (e.g. from 2:00 PM to 4:PM) of booking. The website will generate the booking report including mother’s data, babysitter’s contact data, number of booked hours, fee rate per hour, fees total amount, and tax (%5). To make a…
Draw the E-R diagram for the above, providing the degree and cardinalities Suppose a medical group XYZ wants to store information about physicians & patients. Each physician has only one specialty. Patient records are shared among the doctors. For each patient visit, information is stored about the visit type (regular office, after hours, house call, etc), a single diagnosis for that visit, and the charge. Assume that a patient may visit more than one of the doctors on a particular day. We assume, however, that a patient never visits the same doctor more than once in one day. Draw the E-R diagram for the above, providing the degree and cardinalities
Can you tell me if there is any mistakes in this diagram?? thats its requirenments: During peak periods, Temporary Employment Corporation (TEC) places temporary workers in companies. TEC’s manager gives you the following description of the business: TEC has a file of candidates who are willing to work. If the candidate has worked before, that candidate has a specific job history. (Naturally, no job history exists if the candidate has never worked.) Each time the candidate works, one additional job history record is created. Each candidate has earned several qualifications. Each qualification may be earned by more than one candidate. (For example, it is possible for more than one candidate to have earned a BBA degree or a Microsoft Network Certification. And clearly, a candidate may have earned both a BBA and a Microsoft Network Certification.) TEC offers courses to help candidates improve their qualifications. Every course develops one specific qualification; however, TEC does not…
Create an ER diagram that correctly describes the database for exams at Campus in Bäcksvängen in accordance with the following description: (Own assumptions must be clearly described.) Staff for various functions are involved in the exams. All staff have a full name and a unique staff code. Some people are examiners on one or more courses. A course has one name and one unique ladok code. For a course, you can add up its points based on the associated elements. One part is part of a course (for example an exam, a laboratory or project). A course can have several different parts. An element has a name, a description, a torque code, one point and two or more grades (eg: U, G, VG). An element can only belong to one course. Since the database is to process the exams, it is obvious that a part like described as an examination has an examination opportunity that is identified, among other things, by the date, start time, end time and that it is possible to calculate total writing time. A…
Draw the ER diagram based on the following specification. A tutorial school is using a database to manage information about teachers, courses, and students. Each teacher is identified by staff_id, has a name, an email address, and a phone number. Each student is identified by student_id, has a name, an email address, and a registration date. Each course is identified by course_id, year, and semester. In addition, each course has a name. Each course is associated with multiple lessons.

Each teacher teaches at least one course. Each student takes at least one course. Each course is taught by one teacher. Each course can be taken by many students.
