                 Azure Cosmos DB is a NoSQL data store. It is different from the traditional relational database where we have a table, and the table will have a fixed number of columns, and each row in the table should adhere to the scheme of the table. In the NoSQL database, you don't define any schema at all for the table, and each item or row within the table can have different values, or different schema itself. Database:  We can create one or more Azure Cosmos database under our account. A database is analogous to a namespace, and it is the unit of management for a set of Azure Cosmos containers. Cosmos Account:  the Azure Cosmos account is the basic unit of global distribution and high availability. For globally distributing our data and throughput across multiple Azure regions, we can add or remove Azure regions from our Azure Cosmos at any time.
