Creating the business objects and interfaces

You will define the information units needed to request and approve loan applications, and create the interfaces that will allow you to integrate your loan application components together.

Business Objects
Applying online

In the image above you can see how to use business objects. A bank customer sends his request by providing information about the loan amount and his name. This information is transferred via the ApplicationBO to the bank. In the following topic you will create all the needed business objects for your loan application.

Interfaces

After you have created the business objects, you need a channel to pass the business object through from one component to another. These channels are called interfaces and they define what data flows from one component to another (input) and in the opposite direction (output).
