Databases play a crucial role in storing, managing, and retrieving data efficiently. In the realm of Microsoft Azure, there are several types of databases available that cater to different needs and scenarios. In this article, we will explore various types of databases related to the Microsoft Azure Data Fundamentals exam.
Azure Cosmos DB is a globally distributed, multi-model database service provided by Microsoft Azure. It offers support for various data models, including key-value, document, column-family, graph, and time-series data. It provides guaranteed low latency, automatic scaling, and high availability across different geographical regions. With comprehensive SLA guarantees, Azure Cosmos DB is an ideal choice for applications requiring global reach and low-latency access.
Example of creating a new Azure Cosmos DB account using Azure CLI:
az cosmosdb create --name
Azure SQL Database is a fully managed relational database service based on Microsoft SQL Server. It provides high-performance, scalable, and secure storage for your relational data. Azure SQL Database offers features such as automated backups, automatic tuning, threat detection, and built-in intelligence for optimizing performance. It also supports various deployment options, including single database, elastic pool, and managed instance.
Example of creating a new Azure SQL Database using Azure Portal:
1. Navigate to the Azure Portal.
2. Select "Create a resource" and search for "Azure SQL Database".
3. Fill in the required details such as server name, database name, resource group, and compute tier.
4. Configure additional settings such as firewall rules, storage, and security options.
5. Click "Create" to provision the Azure SQL Database.
Azure Database for MySQL and Azure Database for PostgreSQL are fully managed database services that offer compatibility with MySQL and PostgreSQL database engines, respectively. These services provide automatic backups, high availability, automated security patching, and built-in monitoring capabilities. With Azure Database for MySQL and Azure Database for PostgreSQL, you can easily migrate your existing open-source database workloads to the Azure cloud.
Example of creating a new Azure Database for MySQL using Azure CLI:
az mysql server create --resource-group
Azure Synapse Analytics is an integrated analytics service that brings together big data and data warehousing. It offers capabilities for ingesting, preparing, managing, and serving data for immediate business intelligence and machine learning needs. Azure Synapse Analytics combines enterprise data warehousing, data integration, and big data analytics into a single unified service. It provides features like data lakes, data pipelines, data exploration, and workspace collaboration.
Example of creating a new Azure Synapse Analytics workspace using Azure Portal:
1. Navigate to the Azure Portal.
2. Select "Create a resource" and search for "Azure Synapse Analytics (formerly SQL Data Warehouse)".
3. Fill in the required details such as workspace name, subscription, resource group, and region.
4. Configure additional settings such as storage account and virtual network.
5. Click "Create" to provision the Azure Synapse Analytics workspace.
Azure Data Lake Storage is a scalable and secure data lake store for big data analytics workloads. It provides unlimited storage capacity and is optimized for big data processing frameworks like Azure Databricks, Azure HDInsight, and Apache Spark. Azure Data Lake Storage supports various data ingestion mechanisms and integrates seamlessly with other Azure services to build end-to-end analytics solutions.
Example of creating a new Azure Data Lake Storage account using Azure CLI:
az storage account create --name

Thanks for the detailed post! Can you explain more about relational databases?
Very detailed explanations on databases! Appreciate the insights.
This blog made the types of databases much clearer for my study plan.
What are key-value databases used for?
They’re great for high-speed data retrievals and session management. Examples include Redis and DynamoDB.
The content on types of databases was well-explained. Thanks for helping!
A well-written blog, but some sections were too technical for beginners.
Hey all, which databases are covered in the DP-900 exam?
The exam covers relational, non-relational, and big data analytics, including services like Azure SQL Database, Cosmos DB, and Synapse Analytics.
Hey, how is Azure Cosmos DB classified?
Azure Cosmos DB is a multi-model database service that supports document, key-value, graph, and column-family data models.
Not a fan of NoSQL databases. I prefer the structure of SQL.
Can someone explain graph databases?
Graph databases are perfect for relationships between entities. Neo4j is a leading graph database.
What are some typical use cases for NoSQL databases?
NoSQL is great for real-time web apps, big data, and content management systems.
Informative post! Appreciate the effort.
Been using MySQL for years. Curious to try a new database type.
Give MongoDB or Neo4j a try, you’ll learn a lot from experiencing a different database model.
Found the section on databases to be slightly confusing. Needed more examples.
Thanks for the examples of different types of databases. Just what I needed.
Thanks for sharing! It was really informative.
I personally prefer relational databases for my projects.
Same here. The ACID properties are crucial for my applications.
Column-family databases sound interesting. What are they?
Column-family databases store data using a column-oriented model. They’re excellent for analytical queries. Apache Cassandra is an example.
Great overview on databases. Would you recommend starting with NoSQL databases while learning?
It depends on your use case. For structured data and SQL knowledge, go for relational. For unstructured data, NoSQL is perfect.
Can someone recommend resources for mastering database fundamentals for the DP-900 exam?
Microsoft Learn modules are a great start. Also, consider exploring online courses on platforms like Coursera and Udemy.
Good post! Can anyone shed light on document-based databases?
Sure! Document-based databases store data in JSON-like format and are flexible with dynamic schemas. MongoDB is a popular example.
Very helpful article on databases! I’m preparing for the DP-900 exam and this is gold!
