These are common terms used in strategic Design of Domain-Driven Design. We can consider this an English word that refers to circumstances of an event, incident, statement, or idea, and in terms of which itвЂ™s meaning could be determined.ДЄpart from Context, Strategic design also talks about Model, Ubiquitous Language, and Bounded Context. Herewith strategic design we are forced to think in terms of a context. It is a design approach that is similar to Object-oriented design where we are forced to think in terms of objects.

The strategic design tools help us to solve all problems that are related to software modeling. The majority of frameworks under Spring data family is built considering Domain-Driven design approach. The programmers or developers usually deal with tactical design tools but if we have knowledge and a good understanding of strategic design tools then it will help us in architecting good software. It is not the customerвЂ™s job to know what they wantвЂќ вЂ“ Steve JobsДomain-driven design talks about two kinds of design tools, first one is Strategic design tools and another one is Tactical design tools. According to Eric Evans, When we are developing software our focus should not be primarily on technology, rather it should be primarily on business. Also if system does not solve business need is of no use to anyone No matter how pretty it looks or how well architecture its infrastructure. Suppose we have designed software using all latest tech stack and infrastructure and our software design architecture is fabulous, but when we release this software in market, it is ultimately end user who decides whether our system is great or not. The business logic of an application is a set of rules and guidelines that explain how business object should interact with each other to process modeled data.ДЄ domain in software engineering field is business on which application is intended to build. Basically, business logic is area of knowledge around which application logic revolves. In the process of application development, term domain logic or business logic is commonly used. The word Domain used in context of software development refers to business. Before discussing topic in detail letвЂ™s try to focus some light and understand what is mean by domain in this context. It is an approach for architecting software design by looking at software in top-down approach.

After discussion with team, we identified the desired system and sub-systems, their functions and created the boundary, meaning identified the bounded contexts using DDD traditional approach.We also identified core domain and other sub-domains, mapped these with their sub-functions in a rough diagram which we generally do in DDD to identify the boundary between context.

When you were noting down all the business functions/areas and sub-functions/areas, you were actually identifying the sub-domains (or in simple words the sub-system).

And, you involved business expert in all the discussion which is what we do in DDD and refer the business expert as the Domain expert, right?.

When you were understanding the business problem, you were actually analyzing the domain (or in simple words the complete System).

In fact, this article talks about Strategy phase of Domain driven design how let us see it again. Now, you are thinking where you have used domain driven design which is recommended approach.
