How many microservices have you used for database operations in your projects?

In projects where I worked with microservice architecture, the number of microservices interacting with the database ranged from 3 to 7. Usually, each microservice is responsible for its own business logic and has its own database or schema, which helps isolate data and reduce interdependencies.

For example, in one project, there were microservices for managing users, orders, and payments, each with its own database. This approach simplifies scaling and updating individual parts of the system without affecting others.
