My experience and belief is that conceptual domain modeling occurs in or before use case identification, whether unconsciously or unconsciously. For example,...
Hi, I wanted to start a thread on an issue that seems to put up very frequently: the use of DTO and the trouble and duplication that it generates. My purpose...
... Hi Roni The issue I had with DTOs and duplication was as follows: We were using Java and Hibernate and so we had BOs defined and mapped to our RDMS. This...
I work almost completely in the .NET world where parts of the ADO.NET model (DataSets/DataTables) are touted as DTO and there is much plumbing to handle ...
But I thought use cases were intended to capture the users' requirements in their own words, and from the use cases evolves the domain terminology (ubiquitous...
Here's a story of how a powerful insight, coming at the end of a long chain of refactorings, can bring sudden simplicity to a thorny problem. In the book, Eric...
Hi Dan Thanks for the story. It was inspiring. We have run into similar situations where the originally distinguishing factor (in/out) direction turns out not...
