Parameterization
Parameterization is a software development concept that involves designing code to accept parameters (inputs) that can vary, rather than hard-coding values directly. This makes systems more flexible, reusable, and easier to maintain by allowing behavior to be customized without modifying the underlying code. It is widely applied in functions, queries, configurations, and testing to enhance modularity and security.
Developers should use parameterization to create adaptable and secure applications, such as in database queries to prevent SQL injection attacks by using parameterized queries instead of string concatenation. It is essential for building reusable functions, dynamic APIs, and configurable systems, reducing code duplication and simplifying updates across different environments or use cases.
