Relational data uses keys and relationships to enforce relationships between different tables.
In a relational database, data is organized into tables, which consist of rows and columns. Each row represents a single record or entity, and each column represents a specific attribute or property of that record.
Keys play a crucial role in establishing relationships between tables. A primary key is a unique identifier for each row in a table, ensuring its uniqueness and providing a way to reference that row from other tables. Foreign keys are used to create relationships between tables by linking a column in one table to the primary key column in another table.
