Enhanced ER Model

The enhanced ER model is an abbreviation for Enhanced Entity-Relationship (EER) model. As you know, the entity-relationship (ER) model is a pictorial illustration of the relationship between various entities of a domain. In the case of a large amount of data with multiple interrelated entities, the ER diagrams become complex and tough to interpret. For such cases, the need for enhancement in the ER model was observed, and thus, the EER model was designed.

Each course is identified by course_id, year, and semester. In addition, each course has a name. Each course is associated with multiple lessons. A lesson has a lesson number, a location, a date, a start-time, and an end-time. Lesson numbers are sequentially numbers, starting from 1, generated separately for each course. 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.
