An example of an ER diagram for an admission system could include entities such as Student, Course, Department, and Instructor. The Student entity would have attributes like student ID and name, while the Course entity would have attributes like course ID and title. Relationships would be established between entities, such as a student enrolling in a course, which would be represented by a many-to-many relationship between Student and Course entities. The ER diagram would visually represent these entities, attributes, and relationships to illustrate the structure of the admission system.

An ER diagram for a school management system typically includes entities such as Student, Teacher, Course, Classroom, and Enrollment. Relationships between these entities can be depicted using cardinality and participation constraints to show how they are connected (e.g., a student enrolls in courses taught by teachers in specific classrooms). The ER diagram serves as a visual representation of the database schema for the school management system.
