Properties pattern

The Properties pattern in software design manages access to an object's data by controlling how its attributes are read or modified. Instead of directly changing or retrieving data, properties act like controlled doors—allowing developers to add validation, calculations, or other logic during these interactions. This approach keeps data consistent, secure, and easy to maintain, while presenting a clean interface to users or other parts of the program. Essentially, properties make data handling more flexible and reliable without exposing internal details unnecessarily.
