How to manage relationships between tables in SQLite Manager

In SQLite Manager, managing relationships between tables is essential to ensure data integrity and optimize queries. To manage these relationships, you need to understand how primary and foreign keys work in SQLite.

1. Define the primary and foreign keys: Before establishing relationships between tables, it is essential to define the primary and foreign keys. The primary key is a unique field that uniquely identifies each record in a table. On the other hand, the foreign key is a field that refers to the primary key of another table. To create a relationship, you must ensure that the primary key of one table is equal to the foreign key of another table.

2. Establish relationships between tables: Once you have defined the primary and foreign keys, you can establish relationships between tables in SQLite Manager. This is achieved using the instruction FOREIGN KEY when creating a table. For example, if you have a "Customers" table and an "Orders" table, you can establish the relationship between them by referencing the customer's primary key as a foreign key in the orders table. In this way, each order will be associated with a specific customer.

3. Use constraints to maintain integrity: Constraints are a crucial aspect of relationship management in SQLite Manager. When defining a relationship between tables, you can use constraints such as CASCADE, SET NULL o RESTRICT to maintain data integrity. For example, if a customer is removed from the “Customers” table, you can set the restriction CASCADE so that all your orders are also automatically deleted. This avoids inconsistencies in the database.
