DAO pattern in java what is a Business Object

Directly from this oracle article about the J2EE DAO Pattern:

Everything is very clear indeed but the Business Object "participant" (as they call it).

Here I quote the bit I would like more insights about (especially would be useful a real life example (an easy one)).

BusinessObject

The BusinessObject represents the data client. It is the object that requires access to the data source to obtain and store data. A BusinessObject may be implemented as a session bean, entity bean, or some other Java object, in addition to a servlet or helper bean that accesses the data source.

I am trying to use this pattern as an exercise (as a student for the exam OCPJP it requires to understand the DAO Pattern). So far I have my DataSource (mysql database), my transfer object (JavaBean called Person) and my DAO object interfacing properly between the database and the JavaBean (Person).

So again What exactly a Business Object is?

Thanks in advance

Solution

  • Business objects are objects that concentrate all the logic of your application. Use Business Objects to separate business data and logic using an object model.
