integrates data and process concerns into objects
Object – the encapsulation of the data (called properties) that describes a discrete person, object, place, event, or thing, with all the processes (called methods) that are allowed to use or update the data and properties. The only way to access or update the object’s data is to use the object’s predefined processes. |
