Parameterized Query Design Pattern

The Parameterized Query Design Pattern involves creating database queries with placeholders for data inputs. Instead of inserting user inputs directly into the query string, you define parameters and supply the actual values separately. This approach prevents malicious code injection, enhances security, and improves performance by allowing the database to efficiently reuse query plans. Think of it like a template: the query structure is fixed, and specific values are plugged in as needed, ensuring safe and effective communication between your application and the database.
