Introducing DDD

Before we cover the implementation details, let's define DDD's core concepts and building blocks. Let's begin with the definition of DDD.

What is domain-driven design?

DDD is a software development approach for complex needs where you connect the software's implementation to an evolving model.

DDD is suitable for complex domains and large-scale applications. In the case of simple, short-lived Create, Read, Update, Delete (CRUD) applications, you typically don't need to follow all the DDD principles. Fortunately, ABP doesn't force you to implement all the DDD principles in every application; you can just use which principles work best for your application. However, following DDD principles and patterns in a complex application helps you build a flexible, modular, and maintainable code base.

DDD focuses on core domain logic rather than the infrastructure details, which are generally isolated from the business code.
