Explain the concept of Many-to-Many relationship in the context of databases.

A Many-to-Many relationship in databases means that one record in table A can be associated with multiple records in table B, and vice versa.

To implement such a relationship, an additional join table is usually created, which contains foreign keys to both related tables.

For example, in a course management system, students and courses are related Many-to-Many: one student can attend multiple courses, and one course can have many students.

Table structure:

• students (id, name)
• courses (id, title)
• student_courses (student_id, course_id) — join table

This approach allows efficient storage and querying of data with multiple relationships between entities.
