![]() ![]() Some words have different meaning depending on the context they’re used in. Let's start with a simple example where the ambiguity might happen at the terminology level. We'll eventually discover that this definition is rather precise, describing exactly what a context is, but to get a glimpse of that we probably need a few concrete examples. It doesn't say much about expected size, shape or other characteristics of a context. Which might sound rather vague at first read. ![]() "The setting in which a word or a statement appears that determines its meaning" In Domain Driven Design, a Context is defined as: Using the same term, with a very precisely and unambiguously defined meaning, spanning from discussions with the domain expert to the code level, assures that everybody in the team shares the same vision about the domain and the software. Even so, the traditional DDD approach could not be applied blindly to an indefinitely large domain model without compromising the conceptual integrity of the model.Īs shown in Figure 1, the key role of Ubiquitous Language in DDD is to act like an integrity check for our model. In such a place, typical DDD elements such as Entities, Value Objects and Aggregates deliver an emerging order to a complex domain model. This is crucial for creating a safe harbor where high quality design can thrive and deliver its benefits. an open and transparent environment that promotes learning and exploration.a single and shared version of the model (in the application and test code) precisely defined in terms of the Ubiquitous Language, and.the availability of real domain experts and a creative collaboration with them,.an agile process that emphasizes frequent feedback from users and domain experts,.This is achieved by a combination of several factors: Many models at playĭomain Driven Design puts a great emphasis in maintaining the conceptual integrity of the model of your application. In this article we'll explore the many sides of bounded contexts and how to use them in building a context map to support key decisions in a software development project. Different from other well known DDD patterns, context mapping applies to any kind of software development scenario and provides a high level view that might help the developers to take strategic decisions, like whether to go for a full scale DDD implementation or not in their specific project environment. Context Mapping is a general purpose technique, part of the Domain Driven Design (DDD) toolkit, helps the architects and developers manage the many types of complexity they face in software development projects. Many approaches to object oriented modeling tend not to scale well when the applications grow in size and complexity. ![]()
