This diagram is an Entity-Relationship (ER) diagram representing a small academic database structure. Below is a detailed explanation of each component, including entities, attributes, and relationships: ### Entities and Attributes 1. **Instructor (Oval: 10101)** - **Attributes:** - Name: Srinivasan - Salary: 6500 - **Relationship:** - Teaches: Connects instructor to the course section (sec1). 2. **Department (Oval: comp_sci)** - **Attributes:** - Dept_name: Comp. Sci. - **Relationships:** - Int_dept: Connected to Instructor. - Stud_dept: Connected to Student. - Course_dept: Linked to Course. 3. **Student (Oval: 00128)** - **Attributes:** - Name: Zhang - Total Credits: 102 - **Relationship:** - Takes: Connects student to the course section (sec1). 4. **Course Section (Oval: sec1)** - **Attributes:** - Sec_id: 1 - Semester: Fall - Year: 2017 - Classroom: packard-101 - **Relationships:** - Sec_course: Linked to Course (CS-101). 5. **Course (Oval: CS-101)** - **Attributes:** - Title: Intro. to Computer Science - **Relationship:** - Course_dept: Linked to department (comp_sci). ### Explanation of Diagram Flow - The instructor (Srinivasan) is associated with a specific department (Computer Science) and teaches a specific course section (sec1). - The department (Comp. Sci.) is associated with both the instructor (Srinivasan) and the student (Zhang). - The student (Zhang) takes the course section (sec1), which is part of the Computer Science department. - The course titled "Intro. to Computer Science" is identified by the course code CS-101 and is associated with a specific section (sec1). - The course section (sec1) is scheduled in the classroom "packard-101" during the Fall semester of 2017. This ER diagram provides a clear representation of how different entities in an educational setting are related and organized.
