Design an Entity-Relationship (E-R) diagram for a university management system. The system should capture information about the following: . Students, with the following attributes: student ID, name, date of birth, and email address. • Courses, with the following attributes: course ID, course name, and credit hours. • Professors, with the following attributes: professor ID, name, and email address. Additionally, consider the following relationships: • A student can enroll in multiple courses, and a course can have multiple students enrolled. A course is taught by a single professor, and a professor can teach multiple courses. Show all entities, attributes, and relationships in your E-R. diagram, including the cardinality of cach relationship.

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. t -- Each department has a name, code and location. The code is unique for each department. Ş -- Each course may has one or more sections where each section is belong to only one course. 6 -- 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.
Draw an Entity Relationship Diagram (ERD) using Unified Modelling Language (UML) notation according to the below business rules. Your design should be at the logical level – include primary and foreign key fields and remember to remove any many-to-many relationships. Tip: Pay attention to the mark allocation shown below. Sheep farm feed supplier business rules: • All entities must have surrogate primary keys. • A contact person represents one or more suppliers, and each supplier has exactly one contact person. • A supplier supplies many feed products, and every feed product can be supplied by many suppliers. • Each feed product belongs to a specific feed type, and many feed products can have the same feed type.

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…

ENHANCE ENTITY RELATIOSHIP DIAGRAM The entity type PERSON has the following attributes: SSN, name, address (City/State/Zip), date of birth, age, and contact number. The entity also has the three subtypes: CAMPER, BIKER, AND RUNNER. Draw a separate diagram segment for each of the following situations: 1. At a given time, a person must be exactly one of three subtypes. 2. A person may or may not be one of these subtypes. However, a person who is one of these subtypes cannot at the same time be one of the other subtypes. 3. A person may or may not be the one of these subtypes. On the other hand, a person may be any two (or even three) of these subtypes at the same time. 4. At a given time, a person must be at least one of these subtypes.
