How to: What kind of database should we use?
Since the data is not strongly relational, NoSQL databases such as [Amazon DynamoDB](https://aws.amazon.com/dynamodb), [Apache Cassandra](https://cassandra.apache.org/_/index.html), or [MongoDB](https://www.mongodb.com) will be a better choice here, if we do decide to use an SQL database then we can use something like [Azure SQL Database](https://azure.microsoft.com/en-in/products/azure-sql/database) or [Amazon RDS](https://aws.amazon.com/rds).
