In this quick SQL tutorial, learn how structured data fits into a relational model—the table. We explain how columns (attributes) and rows (tuples) make up a table, and why tables are called relations in RDBMS. Using a simple student table example, we clarify key terms such as arity (number of columns) and cardinality (number of rows). Perfect for BCA/MCA/B.Tech students and freshers preparing for placements or interviews in database management. | Gate Smashers
