Let's see how club and club categories should be related. We can imagine it as follows. There are many categories (for example, social influential clubs and technology clubs), club categories can belong to many clubs (for example, there are many technical clubs on campus) There is a possibility). The unique property of this ClubCategory has category_name (data type: string). This is done by creating a new association table (an intermediary between the Club model and the ClubCategory model). The tables club_id and club_category_id have two columns that refer to the corresponding IDs of each model (the id attribute is the primary key for each model, that is, the only one for each record). However, in the relevant table, these primary keys are called foreign keys (to refer to other tables). In addition, we need to add a line to the bottom of the Club model.

In an SQL database, we start with two tables, student and club; each project has a primary key (id). Next, we use the third table (members) to show the relationship between paired IDs (students and clubs). After that, you can search the club for members of the club's student ID. With student ID, you can find students yourself.
