Go to SQL QueriesWhat is Relational Databases?
A relational database is a type of database that stores and provides access to data points that are related to one another. Relational databases are based on the relational model, which is a way of representing data in tables. Each table has a set of columns and rows, and each row represents a single record.
Board notes: Covered by AQA, Edexcel, and OCR. Students should be able to design and create relational databases and to use SQL to query them.
Step-by-step explanationWorked example
A database for a school might have a table for students and a table for courses. The students table would have columns for student ID, name, and address. The courses table would have columns for course ID, name, and teacher. A third table, called enrollments, would be used to link students to courses. This table would have columns for student ID and course ID.
Mini lesson for Relational Databases
1. Understand the core idea
A relational database is a type of database that stores and provides access to data points that are related to one another. Relational databases are based on the relational model, which is a way of representing data in tables.
Can you explain Relational Databases without copying the notes?
2. Turn it into marks
A database for a school might have a table for students and a table for courses. The students table would have columns for student ID, name, and address.
Underline the method, evidence, or command-word move that would earn credit in A-Level Databases & SQL.
3. Fix the likely mark leak
Watch for this mistake: Confusing tables, records, and fields.
Write one correction rule before doing another practice question.

Frequently asked questions
What is a primary key?
A primary key is a column in a table that uniquely identifies each row in the table. For example, in a students table, the student ID would be the primary key.
What is a foreign key?
A foreign key is a column in a table that refers to the primary key of another table. It is used to create a relationship between the two tables. For example, in the enrollments table, the student ID would be a foreign key that refers to the students table.
