DOMAIN DRIVEN DESIGN AS A BASIS FOR MICROSERVICE MODELING IN E-COMMERCE

Abstract

In today’s world of e-commerce, where competition is constantly increasing, effective software system modeling is a key success factor. One of the most promising approaches to solving this problem is Domain Driven Design (DDD), which allows developers to create software systems that accurately reflect business logic and easily adapt to market changes.DDD encourages developers to focus on the business domain by creating a common language (Ubiquitous Language) between developers and domain experts. This helps to avoid misunderstandings and ensures that business requirements are accurately reflected in the code.DDD includes eight key concepts: Domain Driven Design, Business Entities, Model Boundaries, Aggregation, Entities vs. Value Objects, Operational Modeling, Layering the architecture, Build the domain model.One of the key concepts of DDD is aggregates – groups of objects that are treated as a single unit. Aggregates provide encapsulation and data integrity, which is especially important when developing microservices.Microservices is an architectural style that involves developing software systems as a set of small, independent services. DDD is ideal for modeling microservices because it allows developers to break down a complex system into small, manageable parts, each of which is responsible for a specific business function. Applying DDD in e-commerce can significantly improve software quality, reduce development time, and increase customer satisfaction. With DDD, companies can create more flexible and adaptive systems, allowing them to respond quickly to market changes and customer needs.This article discusses the basic principles of DDD and their application for modeling microservices in e-commerce. It shows how DDD can help developers create more efficient and scalable systems that meet business needs.
