If you make a traditional 3-layered application, this logic goes in the presentation layer. So, there is no DDD answer to where the presentation logic goes, besides not in the domain. Each bounded context should have a clear and well-defined purpose, and. It describes how your system interacts with clients, which are external actors and is specific to your application: if you make a web or a mobile version of your app, chances are that you will have the same domain implementation but your presentation logic will slightly differ. In domain-driven design, bounded contexts are used to define clear boundaries between different areas of the business domain. It can be a talk, a presentation, a code project with physical boundaries defined by the artifact. It is an area where a certain sub-domain makes sense, while the others don’t. ![]() What you describe is called presentation logic and does not describe your business logic. Bounded context defines tangible boundaries of applicability of some sub-domain. The Bounded Context Canvas is a collaborative tool for designing and documenting the design of a single bounded context. in literature by Vaughn Vernon and Eric Evans, nicely summarized in this Medium article ), a good starting point is to identify Core. you are developing security software that focuses on user sessions), the authentication logic belongs in the application layer. Unless your application focuses on authentication (e.g. On most applications, The login system does not belong in the domain layer. They build a Bounded Context to handle some part of their. 3 Answers Sorted by: 1 You sort of answered your own question right at the end. Lets say we are in a company that sells coffe mugs, providing a Domain-Driven Design approach for their architecture needs. Bounded Context Ownership: Do Not Bleed This one catches out lots of teams working with DDD, especially when push comes to shove. RT NoxMarCoding: Day 152 (yesterday) of 100DaysOfCode: - Finished logic and API for first bounded context in a project for my uni applying DDD - Added some Blazor components to GUI for this project. DDD does not state anything about how to you should structure your application, it can be applied to any architecture. Bounded Contexts in Domain-Driven Design. The main rule of DDD is what describes the business goes in the domain, everything else does not. In Domain-Driven Design (DDD), a bounded context is a boundary within which a particular domain model exists and is valid. This model should be ubiquitous, meaning different applications should share the same business logic. ![]() Where this code goes depend on the structure of your application.ĭDD is a set of patterns and rules that helps you model your business.
