Answer
Microservices require separate databases to maintain independence and scalability.
In microservices architecture, each service should own its data to ensure that it can scale independently and be updated without impacting others. This pattern, known as Database-per-Service, allows teams to choose the best-fitting database for each service. For example, an Order service might use a relational database for transactional integrity, while a Product service could use a NoSQL database for flexibility and performance.
