Explanation

The Observer pattern defines a one-to-many dependency between objects so that when one object (the subject) changes state, all its dependents (observers) are notified and updated automatically. This is commonly used in event handling systems. 'DataAccess', 'Publisher', and 'Subscriber' are not standard design pattern names for this purpose.
