Approaches to SQL
Declarative approach: In this approach, you specify what you want to achieve, and the database system determines how to execute the request. It is the most common approach.
Procedural approach: This approach specifies the exact steps the database system should take to execute a request. This approach is less common and is often used for more complex tasks that cannot be easily expressed using declarative SQL statements.
Hybrid approach: Some database systems permit you to utilize a combination of declarative and procedural techniques, enabling you to take advantage of the strengths of both approaches.
Object-oriented approach: Some database systems also support an object-oriented approach.
A good knowledge of the database’s underlying structure and the data it contains is essential to work with SQL effectively.
