# Azure Cosmos DB

A simple but powerful database option from [Microsoft](https://docs.microsoft.com/en-gb/azure/cosmos-db/sql-api-nodejs-application). Enables creation of JSON objects as records which retains a straightforward relationship between the code and stored data.

Cloud-based databases are much easier to manage, share access and generally use than a traditional Microsoft Access or Excel approach.
