Develop the Data Transfer Object

The three main tasks during the development of the mock user interface are the following:

• The creation of the data transfer object
• The mock service
• The mock user interface

We will go over them one by one.

Data transfer object

The ClientDto data transfer object has an identifier and the name of the client. Similarly, the AccountDto object has an identifier and a name. The join object ClientAccountDto has an instance of ClientDto and AccountDto.
