An entity object is the ADF business component that represents a row in the specified data source (generally a single database table, view, or synonym) and simplifies modifying its associated attributes. Importantly, it allows you to encapsulate domain business logic to ensure that your business policies and rules are consistently validated.
Can a domain object be a business object?
What you refer to as business objects are called aggregate roots in DDD but the point still stands. I would not extend POCOs to use them as business objects. It will mix domain logic with data logic and the codes become very difficult to maintain in the future.
How to create entity classes in Domain Driven Design?

Why do you need entity objects in business logic?
Importantly, it allows you to encapsulate domain business logic to ensure that your business policies and rules are consistently validated. Entity objects support numerous declarative business logic features to enforce the validity of your data.
Where to place business logic in Domain Driven Design?
Entities are the first natural place we should aim to place business logic in domain-driven applications. In this article, we talk about the roles and lifecycle of an entity in Domain-Driven Design. This is part of the Domain-Driven Design w/ TypeScript & Node.js course.
