sry about this question, but english is not my mother language, and iam reading the book and couldnt understand the exact meaning of this sentence, more specifically of the expression "runtime realization":

"the business logic interacts with this object-oriented domain model and its
[b]runtime realization[/b] as a network of interconnected objects."

if someone could help...

thanks in advance.

regards.

Hello friend. I would suspect it means that at runtime, objects are polymorhically resolved and might not actually be the compile time type you may expect.

It means that at runtime your Java application are nodes (instances) and links (pointers) between these nodes. This is a network of nodes.
