The four basic data operations: Create, Read, Update, Delete.
CRUD stands for Create, Read, Update, Delete -- the four fundamental operations for managing data in any application. Almost every feature you build maps to CRUD: creating a new post, reading a list of users, updating a profile, or deleting a comment.
These operations correspond to SQL commands (INSERT, SELECT, UPDATE, DELETE) and HTTP methods (POST, GET, PUT, DELETE). REST APIs expose CRUD through endpoints. In Supabase, you can perform CRUD through the dashboard, SQL, or the JavaScript client Library. Databases are built around CRUD. Mastering CRUD is a milestone because once you can perform these four operations, you can build the data layer of any application.
