The article discusses the concept of polyglot persistence in microservices architecture, emphasizing the importance of choosing the right database for each domain. It highlights a case study of an e-commerce project that utilizes three different databases tailored to specific services. This approach allows for loose coupling and independent evolution of schemas across services.
