What is the domain model?

The

domain model is an outline overview of a specific problem used in software engineering fields and conceptual problems of problems. The purpose of this model is to divide a specific problem down into it and create a visual representation of how a specific process works. With domain models, software engineers can ensure that they understand all the elements of the problem before they start encoding or implement it into a piece of software, hopefully saving time, costs and efforts to complete the overall project. In the development diagram, all different pieces of puzzles are connected in a logical way. For example, in connection with the insurance arrangement, while the original individual covered and his children would all fall into the category of "insured". The child would also fall into the subgroup of the "insured" class: "dependent persons". The visual design of these relationships can improve communication on the project and help all participants remain on the same page.

establishing key concepts and unique vocabulary of a particular problem is one of the first steps to create a domain model. After the introduction of various classes and subclass - for example "dependent", "insured" and "insurance plan" - requires the creation of a domain model to link these classes in a logical order and show how they work regularly. For example, "dependent persons" will rarely interact directly with the insurance company; All dependent interactions will be the intermediary, the original insured side. For this reason, the "dependent" class will be associated with the "insured" and "insured" Linked class on the "insurance plan", without direct connection between "addicted" and "insurance plan".

The primary benefit of the domain model is that it clearly defines and encapsulates the problem and leaves nothing outside. By performing this level of in -depth planning before the actual initiation of the project coding, the problem is often easier to solve, which leads to a brighter and more conciseMu code. Without a domain model, repeated code and ineffective arrangement of classes and routines may occur. Just as an attempt to write complex paper without a clear outline in advance, things are drastically simplified by a good work plan.
