This article provides an overview of the Azure database solutions described in Azure Architecture Center.
Azure Database solutions include both traditional relational database management system (RDBMS) and big data solutions.
RDBMS workloads include online transaction processing (OLTP) and online analytical processing (OLAP). Data from multiple sources in the organization can be consolidated into a data warehouse. You can use an extract, transform, and load (ETL) process to move and transform the source data.
A big data architecture is designed to handle the ingestion, processing, and analysis of large or complex data. Big data solutions typically involve a large amount of non-relational data, which traditional RDBMS systems aren't well suited to store. This type of database is referred to as NoSQL (not only SQL).
This article provides resources to learn about Azure databases. It outlines paths to implement the architectures that meet your needs, and best practices to keep in mind as you design your solutions.
There are many architectures for you to draw from to address your database needs. We also provide solution ideas for you to build on, which include links to all the components you need.
Learn about databases on Azure
If you're new to databases on Azure, the best place to start is Microsoft Learn. On this free online training platform, you'll find videos and tutorials that offer hands-on learning. Microsoft Learn offers learning paths that are based on your job role, such as developer or data analyst.
Here are some Learn modules you might find useful:
- Choose a data storage approach in Azure
- Design your migration to Azure
- Deploy Azure SQL Database
- Explore Azure database and analytics services
- Secure your Azure SQL Database
Path to production
To find options helpful for dealing with relational data, consider these resources:
- To learn about resources for gathering data from multiple sources and how to and apply data transformations within the data pipeline, see Extract, transform, and load (ETL).
- To learn about Online analytical processing (OLAP), which organizes large business databases and supports complex analysis, see Online analytical processing.
- Online transaction processing systems record business interactions as they occur. For more information, see Online transaction processing (OLTP).
A non-relational database doesn't use the tabular schema of rows and columns. For more information, see Non-relational data and NoSQL.
To learn about data lakes, which hold a large amount of data in its native, raw format, see Data lakes.
A big data architecture can handle ingestion, processing, and analysis of data that is too large or too complex for traditional database systems.
- For more information, see Big data architectures.
- To learn about designing a system that scales well as data grows, see Build a scalable system for massive data.
- To learn more about Azure Databricks, an Apache Spark–based analytics service for big data analytics and AI solutions, see Monitoring Azure Databricks.
A hybrid cloud is an IT environment that combines public cloud and on-premises datacenters. For more information, see Extend on-premises data solutions to the cloud.
Azure Cosmos DB is a fully managed NoSQL database service for modern app development. For more information, see Azure Cosmos DB resource model.
To learn about the options for transferring data to and from Azure, see Transfer data to and from Azure.
