Query design involves creating well-structured SQL queries to retrieve data from the SQLite database based on the defined relations and leveraging the functionality of the metamodel.
When designing queries, we can leverage the information provided by the metamodel to navigate the relations between tables. For example, if the metamodel specifies that there is a relationship between the “Users” and “Orders” tables, we can use this information to construct a query that joins these tables based on the appropriate foreign key constraint.
By understanding the relations in the SQLite database and utilizing the guidance of the metamodel, we can design queries that retrieve data from related tables, incorporate filtering conditions, and perform aggregations or other operations as required. This allows us to retrieve the desired information, establish connections between different entities, and gain valuable insights from the data stored in the database.
