Lets learn how to use DDD architecture approach.

Introduction

We will take a look at DDD with a practice approach "learn by examples".

It this series we will take a look at examples based on ours client Product reservation.

Key Indicators for Applying DDD:

When not to apply DDD:

Simple or Small Applications.

If you're building a small, straightforward application (like a simple CRUD app, a prototype, or a single-purpose tool), DDD may add unnecessary complexity. In such cases, simpler design patterns or frameworks may be more suitable.
Short-Lived Projects.

For projects with a short lifespan or a limited scope where quick delivery is more critical than long-term maintainability, DDD may be overkill.
Low Domain Complexity.

If the business domain is relatively simple and doesn’t complex hard rules or logic, the overhead of DDD might not be justified. Applications that do not have a deep or evolving domain don't benefit much from DDD.
Lack of Domain Expertise.

DDD relies heavily on domain experts and collaboration. If the domain experts are not available or there is no buy-in from stakeholders to invest time in defining and refining the domain model, DDD won't be effective.
Tight Deadlines and Budgets.

DDD requires upfront investment in understanding the domain, modeling it, and creating a well-structured design. If the project has very tight deadlines or budget constraints, the initial investment required for DDD may not be best decision.
