How is querying in a mapping table efficient over single entity table in case of many to many relation Like for the user skills relation instead creating a separate mapping table and then querying on it (no. of rows would be numOfUsers x numOfSkills in worst case) instead of adding references to User and Skills table with user table containing field "skills" storing list of skill_id and vice versa in case of skill table having references to usersID, then querying for the users with same skill would be efficient as it would only have numOfSkills rows At 5:00 you mentioned criteria to be the number of rows only then by creating a mapping table the number of rows would eventually increase please clear my doubt
