Developing Microservices with Quarkus

# NoSQL use cases

NoSQL databases are generally used for e-commerce. In cases like these, the product being sold might be very different, so having a common schema is not possible. However, having a schema for each product is also not possible when there is a large variety of products.

Using NoSQL solves this issue; we don’t have to worry about the schema, and we can save what we need. However, we should always define common mandatory fields (ID, price, etc.), so creating a parent type and using inheritance is necessary when working on bigger projects.
