Using a Non-Relational Database

So far, we have learned that relational databases store data using table columns and rows. All these table records are structurally optimized and designed using different keys, such as primary, unique, and composite keys. The tables are connected using foreign/reference keys. Foreign key integrity plays a significant role in the table relationship of a database schema because it gives consistency and integrity to the data that’s persisted in the tables. Chapter 5, Connecting to a Relational Database, provided considerable proof that FastAPI can connect to relational databases using any of the present ORMs smoothly without lots of complexities. This time, we will focus on using non-relational databases as data storage for our FastAPI microservice application.

If FastAPI uses ORM for relational databases, it uses Object Document Mapping (ODM) to manage data using non-relational data stores or NoSQL databases. There are no tables, keys, and foreign...
