Imagine you are building a Go program to manage a university's student and course data. How would you design the structs to model the relationships between students, courses, and instructors?
- Create a 'Student' struct with attributes like 'ID,' 'Name,' and 'EnrolledCourses,' which is a slice of 'Course' structs. Each 'Course' struct contains details like 'CourseID,' 'CourseName,' and 'Instructor' (an 'Instructor' struct with attributes like 'InstructorID' and 'InstructorName'). This way, students can enroll in multiple courses, and each course has an associated instructor.
- Define separate 'Student,' 'Course,' and 'Instructor' structs. 'Student' contains attributes like 'ID' and 'Name.' 'Course' includes 'CourseID' and 'CourseName.' 'Instructor' contains 'InstructorID' and 'InstructorName.' Use references or IDs to establish relationships between these structs.
- Create a 'UniversityData' struct with nested slices or maps for 'Students,' 'Courses,' and 'Instructors.' Each slice/map holds individual student, course, or instructor details. This approach simplifies data management but may lead to complex code when handling relationships and queries.
- Define interfaces for 'Student,' 'Course,' and 'Instructor' and implement them in respective structs. This provides flexibility in struct design but can be less intuitive for understanding relationships.
To model the relationships between students, courses, and instructors in a Go program for university data management, create a 'Student' struct with attributes like 'ID,' 'Name,' and 'EnrolledCourses.' Each 'EnrolledCourses' entry is a 'Course' struct, which includes 'CourseID,' 'CourseName,' and an 'Instructor' struct. This 'Instructor' struct contains attributes like 'InstructorID' and 'InstructorName.' This approach allows students to enroll in multiple courses, and each course is associated with an instructor. It provides a clear representation of the relationships between these entities and facilitates data management.
