Azure Cosmos DB Multi-Model

Azure Cosmos DB is a fully managed NoSQL database service that provides high availability, scalability, and low latency. It supports multiple data models and offers a unified programming model to interact with these models.

• Multi-Model Database: Supports various data models such as document, key-value, graph, and column-family.
• API Support: Provides APIs for SQL, MongoDB, Cassandra, Gremlin, and Table.
• Global Distribution: Data can be distributed globally with low latency access.

1. Document Model
2. Key-Value Model
3. Graph Model
4. Column-Family Model

Each model allows different ways to store and query data, making it flexible to meet various application needs.

4.1 Create a Cosmos DB Account

Follow these steps:

1. Log in to the Azure Portal.
2. Click on "Create a resource".
3. Select "Databases" and then "Azure Cosmos DB".
4. Choose the API you want to use (e.g., SQL API).
5. Fill in the account details and click "Create".

4.2 Create a Database and Container

Once the account is created, you can create a database and container:

const { CosmosClient } = require('@azure/cosmos');

const client = new CosmosClient({ endpoint: "", key: "" });
const database = await client.databases.createIfNotExists({ id: "myDatabase" });
const container = await database.containers.createIfNotExists({ id: "myContainer" });

• Use partition keys wisely to optimize performance.
• Regularly monitor and adjust throughput settings.
• Implement proper data modeling according to your application needs.
