When you create a binary component, it also means that you need to use late binding and reflection to find what you need with special functionality code. Reflection is a powerful tool, and it allows you to write dynamically configurable software.

In contrast to imperative programming, a statement-type program can describe the behavior of a software in a simpler, clearer way. Declaration programming means defining the behavior of a program with a declaration, rather than writing some
