Relational Model
Learn how the relational model connects entities using keys so your SQLite schema reflects real-world data clearly.
Foreign Keys
Define and enforce foreign keys in SQLite, including enabling foreign key checks per connection.
Cascading Actions
Configure SQLite foreign key actions like CASCADE, SET NULL, and RESTRICT for predictable parent-child behavior.
One-to-One Relationship
Implement one-to-one relationships in SQLite using a foreign key plus UNIQUE constraint.
One-to-Many Relationship
Model one-to-many relationships in SQLite where one parent row can be referenced by many child rows.
Many-to-Many Relationship
Build many-to-many relationships in SQLite using a junction table with two foreign keys.
