Data encapsulation is the concept of restricting access to an object's state (i.e. its data and variables) to a set of method calls, which ensures that the data remains safe and consistent. In other words, users can only interact with the object through its methods, rather than directly modifying its internal state. This helps to prevent errors and maintain the integrity of the code. Inheritance and polymorphism are related concepts, but they do not directly involve the restriction of external access to an object's state. Data modeling is a broader term that encompasses many different aspects of software design, including data structures, relationships, and constraints, but it does not specifically refer to data encapsulation.
