Draw an Entity relationship diagram (ER) for a university according to the following rules: +-- For each student the university needs to keep track of: first name, last name, student id, address, phone no and their major. - The student id is identical for each student. > -- Each course has a number, name and credit. The course number is unique for each course. +-- Each department has a name, code and location. The code is unique for each department. - Each course may has one or more sections where each section is belong to only one course. +--A department offers one or many courses. 7- Some courses have perquisite courses. 8- Each student could register in one or more courses. In your diagram you need to show the following: 1- The primary key for each entity. 2- The cardinality and participation between entities.

create an Enhanced Entity-Relationship (EER) diagram based on the provided information. Based on the following description, try creating the diagram using a tool such as draw.io, Lucidchart, or any other ER diagram tool: Entities: Person: person_ID (PK), name, address, birth date, phone number Subtypes: Employee, Physician, Patient, Volunteer Visit: date (PK, partial identifier), comments Care Centre: care_centre_ID (PK), name, location Laboratory: lab_ID (PK), name, location Bed: bed_number (PK), room_number, care_centre_ID (FK) Item: item_number (PK), description, unit_cost Treatment: treatment_ID (PK), treatment_number, treatment_name, treatment_date, treatment_time, results Relationships: Works_In (Person - Care Centre): Person (1, M) ----< Works_In >---- (1, M) Care Centre Assigned_To (Employee - Care Centre): Employee (1, M) ----< Assigned_To >---- (1, M) Care Centre Assigned_To (Physician - Care Centre): Physician (1, M)…
Draw an Entity Relationship Diagram for all of those below. Draw an ER diagram to represent information about students. A student is identified by his/her student number. Student’s name (first and last), permanent address, phone number, gender and date of birth are also stored. An airplane has a registration number, type, number of economy class seats, number of business class seats and the year of production. Some students live in student halls. Each hall has a name (unique) and an address. Each student has a number (unique) and a name. Assume that there are students living in every hall. Each text book has a unique ISBN (International Standard Book Number), and contains several chapters. Each chapter has a chapter number (unique within a book), the number of pages and the number of references. A chapter covers a single topic, but the same topic may be covered in various books. Each lecturer is identified by a unique number, name and phone. A lecturer teaches several courses, and for…
Use ER Assistant to draw your diagram. Draw a self-referencing entity type for the Employee entity type for which an employee is supervised by a maximum of one other employee and doesn’t have to be supervised by any employee at all. Conversely, an employee can supervise zero or many other employees. The attributes of the Employee entity are as follows: EmpNo (primary key), EmpName, EmpAddress.

Draw an Entity Relationship Diagram for the following scenario A, B, and C are entities. There is a relationship between all three, called D. For each A and B there is one C. For each B and C there can be many A’s. For each A and C, there is one B. Every time the relationship, D, is satisfied, a single value, “Note”, will be stored
Provide a separate ER diagram representing each of the following situations. 1.A is an entity. It has an attribute, “a_id” as its identifier. B is a weak entity that depends on A. It has “b_id” as its discriminator. Many instances of B may belong to the same instance of A. 2. A, B, and C are entities. There is a relationship between all three, called D. For each A and B there is one C. For each B and C there can be many A’s. For each A and C, there is one B. Every time the relationship, D, is satisfied, a single value, “Note”, will be stored.
answer should be handwritten and the ER MODEL should be be completeDraw the Entity Relationship Diagram (ERD) with appropriate mapping cardinalities for the following scenario, Patients are treated in a single ward by the doctors assigned to them. Healthcare assistants also attend to the patients; a number of these are associated with each ward. Each patient is required to take a variety of drugs a certain number of times per day and for varying lengths of time. The system must record details concerning patient treatment and staff payment. Some staffs are paid part time and doctors and healthcare assistants work varying amounts of overtime at varying rates, the system will also need to track what treatments are required to what patients
Draw an ER-Diagram for this situation and place minimum and maximum cardinalities on the diagram? Entity type: • EMPLOYEE with attribute: EmpID , Name (Firstname :besan, Lname) , Address :Amman, Birth_of_Date25/5/02 . • DEPARTMENT with attribute : DeptID , DeptName , Loc Relationship: Works_in Relationship between EMPLOYEE and DEPARTMENT and each employee is works in zero or many department and each department worked by one or many employee.

Suppose that we wish to keep a genealogy. The information we wish to record about each person includes their name, date of birth, phone number, and degrees obtained . We also need to keep track of the mother, father, and children of each person. Draw a complete Entity-Relationship diagram. You must include all the details, sad as keys, weak entities (if any), cardinality constraints, etc. Your diagram must avoid redundancy.
