/*
Internally a lend is stored with an id
but the client shouldn't be allowed to set or change it
therefore the package 'AutoMapper' is used to prevent errors
that could happen when doing this task manually.
It takes the information from the client and maps it to the
corresponding internal object which then will be returned.
Furthermore it could be used to keep some attributes secret.
Another nice effect of this is that the implementation could be changed
while the interface could be retained by some minor changes in the code.
DTO stands for Data Transfer Object
