Does each Microservice have its own database?
The short answer is yes.
In order to be able to independently develop microservices , they must be loosely coupled.
Each microservice’s persistent data must be private to that service and only accessible via it’s API ..
Can two Microservices use same database?
2 Answers. You are not likely to benefit from a Microservices architecture if all the services share the same database tables. This is because you are effectively tightly coupling the services. … No direct database access is allowed from outside the service, and there’s no data sharing among the services.

What is the use of data sharing?
Benefits of data sharing It enables better research and development, and the delivery of better products. Sharing data enables unprecedented collaboration and data-driven decision-making, informing policy and amplifying social impact.
Which database is best for Microservices?
Different services have different data storage requirements. For some services, a relational database is the best choice. Other services might need a NoSQL database such as MongoDB, which is good at storing complex, unstructured data, or Neo4J, which is designed to efficiently store and query graph data.
Is it a good idea for Microservices to share a common database?
I’ve seen folks refer to this idea in part, trivially, as “each microservice should own and control its own database and no two services should share a database.” The idea is sound: don’t share a single database across services because then you run into conflicts like competing read/write patterns, data-model conflicts …
Does Microservices use SQL database?
Relational databases You’ll have to start building microservices with what you have – a relational database, such as DB2, MS SQL Server, MySQL, PostgreSQL, and gradually split it into several small services. On top of that, you can use a relational database in microservices if you apply polyglot persistence.
