Lecture 383:- Polymorphic Relations
Polymorphic relations in databases allow a table to have a relationship with more than one other table on a single association. This means that a table can belong to multiple tables on a single column.
For example, imagine you have two tables, comments and posts, and you want to associate comments with either posts or other comments. In this case, you can use a polymorphic relationship to allow a comment to belong to either a post or another comment, rather than creating separate post_comments and comment_comments tables.
Polymorphic relationships are useful when you have a situation where multiple tables can belong to another table on a single association. This can simplify your database schema and make it easier to manage your data. However, it can also make querying the data more complicated, as you may need to use more complex SQL queries or join multiple tables to get the data you need.
