A domain model is a visual representation of real situation objects in a domain. A domain is an area of concern. Its used to refer to the area you are dealing with. The model is a diagram, for domain models the class diagram UML is mostly used. The …

2013年5月31日 · A Conceptual model in the field of computer science is also known as a domain model. a conceptual model represents 'concepts' (entities) and relationships between them. But on the domain model page it says . A domain model in problem solving and software engineering is a conceptual model of all the topics related to a specific problem.

2010年8月18日 · It doesn't mean that Domain Modeling ignores data structures. It just puts more emphasis on operations and how they can be uses to solve problems. I don't know much about other than Domain Driven Design domain modelling techniques, but DDD involves (apart from modeling data and behavior) also explicit modelling of consistency boundaries ...

2013年3月21日 · The terms you are confused about are: "domain objects", "domain entities" and "model objects". While usually used interchangeably, the domain entities and model object can also be instances of active record pattern (basically: domain objects with added storage logic). In ordinary domain object there is no storage logic. It gets handled by data ...

2016年3月19日 · An domain model on the other hand, is a conceptual model used in analysis of a problem domain. It describes the domain in terms of entities that have relations, data and behaviour. It describes the responsibilities of those entities as relevant for understanding the problem domain. BTW an excelent and very short introduction to UML is:

2010年7月12日 · To me, Domain-Driven Design (DDD) is more "all emcompassing"; where as Use Cases are just a tool that focus on a specific view: how a something responds to stimulus and are used to capture or document behavioral requirements. To me, the term "domain" is a loaded one - it infers a wider view of all the concepts relevant to a specific problem area.

2013年12月11日 · A Domain Model needs both structure and behaviour if it's to model the problem space in any useful way. So you'll need to augment the class diagram with some behavioural description; e.g. state models and/or actions.

2019年7月5日 · A domain model (the term is not at all Java specific) is a class that models something in the problem domain, as opposed to a class that exists for technical implementation reasons. Domain model instances often need to be persisted in a database, and in Java, they typically conform to the Java Beans specification, i.e. they have get and set ...

2011年10月14日 · For a new project about to start, I'm looking for a simple Windows-based tool for domain-driven modeling - something like "digital CRC's" (Collaboration Responsibility Cards) that would allow me to easily: define the entities involved; define their properties (and metadata about those properties) define the links between those entities

2019年2月25日 · When looking up a realm, should the repository-layer use the setter methods from the domain model to construct the realm aggregate? I tried with a DTO implementation placed in the same package (dto_sql.go) that encoded/decoded to/from the realm aggregate, but it kind of felt wrong having that concern placed in the domain package.
