Driving design with use cases.

Domain driven design use cases. Agile enterprise software development using domain driven design and test first by einar landre harald wesenberg and jørn ølmheim. By definition the problem domain is the set of specific problems that are considered members of that domain. There is a very good white paper on the capgemin slideshare uses cookies to improve functionality and performance and to provide you with relevant advertising.

It describes independent problem areas as bounded contexts each bounded context correlates to a microservice and emphasizes a common language to talk about.

It builds the initial static portion of a model which is essential when driving your application design forward from use cases.

Short presentation of how smart use cases and domain driven design can trigger model driven development. Domain driven design use case. In the context of building applications ddd talks about problems as domains.

Domain driven design ddd advocates modeling based on the reality of business as relevant to your use cases. Unless ddd has a really weird use for the term use case then they are not the same thing. David arno feb 19 18 at 12 18.
