![]() Thus an entity can be uniquely identified using an ID. ![]() However, there can be changes in the state of some or all the properties (except identity). This identity remains unchanged during the entire life span. The instances of an entity class possess a global identity. While modelling a domain-driven software, the following conceptual tools are useful: EntityĪn entity is a class having properties associated with it. Model a Software using Domain-Driven Design It also acts as a threshold within which a particular domain model is applicable and valid. Bounded Contextīounded context is a description of a boundary in which the domain model is defined. For example, nouns and common verbs related to domain are used to name classes and methods respectively. ![]() Thus, Ubiquitous language is a common language acting as a means of communication between developers and domain experts. Ubiquitous Language facilitates that communication. Ubiquitous LanguageĪs already mentioned, DDD helps to build a communication channel between software developers and domain experts. In a nutshell, the model helps in solving business problems. It also provides the core logic that the application implements. On the other hand, the model refers to the prospective solution to that problem. In order to strategically design software, the domain-driven design brings the following terms in scope: ModelĪs already mentioned, the domain is the knowledge or data around the problem that the software attempts to solve. Terminology related to Domain-Driven Design For example, a bank manager would be a domain expert for a banking system. Domain experts are the people having concrete knowledge of the business area that software targets. It builds a communication channel between domain experts and software developers. ![]() The goal of domain-driven design is to model software that domain experts can understand. Domain provides a set of guidelines that define the interaction of business objects with each other to process modelled data. The domain is the area of knowledge around which application revolves. ![]() However, in the context of software development, it refers to the business idea that software is attempting to model. The dictionary meaning of domain is “ Sphere of Knowledge“. The domain is the heart of the software around which the application revolves. It suggests designing software architecture by looking at it in a top-to-bottom fashion. It is an architectural approach to designing large systems. Domain-Driven Design is a concept introduced by Eric Evans in his book Domain-Driven Design: Tackling Complexity in Heart of Software. ![]()
