Final answer:
The Object-Relational Model supports inheritance, encapsulation, polymorphism, and object identity.
Step-by-step explanation:
The Object-Relational Model supports several common object-oriented features. One of these features is inheritance, which allows objects to inherit properties and methods from their parent classes. This enables code reuse and simplifies the design of complex database schemas. Another feature is encapsulation, which allows data to be hidden and accessed through methods, providing improved security and data integrity.
Polymorphism is also supported in the Object-Relational Model. This means that objects can be represented by different data types, allowing for flexibility in querying and manipulating data. Lastly, the model supports the concept of object identity, which means that each object has a unique identifier that can be used to distinguish it from other objects.
