Microsoft has introduced the SQL Database in Microsoft Fabric. In this article, we compare the traditional Azure SQL Database with the new SQL Database in Fabric, highlighting their main differences, pros and cons, and use cases to help you make an informed decision.

Key Differences Between Azure SQL Database and SQL Database in Fabric

Here's a table highlighting the main differences:

Pros and Cons of Each Database Type

Below are the main pros and cons of the Azure SQL Database.

Below are the main pros and cons of the SQL Database in Microsoft Fabric.

When to Choose Azure SQL Database

Scenario: A financial services company relies on complex data models in Power BI that connect directly to an Azure SQL Database. They require fine-grained control over database performance and security settings to comply with stringent regulatory requirements. The organization has invested in performance tuning and uses advanced features like columnstore indexes and in-memory OLTP to optimize query speeds.

Why Azure SQL Database is a better choice?

• Control Over Configurations: Ability to optimize database performance for complex queries and large datasets, which is crucial for their Power BI reports.
• Advanced Features: Supports specialized features like in-memory OLTP and columnstore indexes that enhance analytical query performance.
• Established Integration: Existing workflows and data models are built around Azure SQL Database and Power BI Direct Query mode.
• Security Compliance: Detailed control over security settings to meet regulatory standards.

When to Choose SQL Database in Microsoft Fabric

Scenario: A retail chain wants to allow their data analysts to create real-time Power BI reports based on transactional sales data. They prefer minimal administrative overhead and aim to reduce the time from data generation to actionable insights. The team is also interested in using other Microsoft Fabric services, like notebooks and AI capabilities.

Why SQL Database in Fabric is a better choice?

• Integrated Analytics: Automatic replication of transactional data to OneLake in near real-time makes data immediately available for Power BI reports.
• Direct Lake Mode: Power BI can connect to the data stored in OneLake using Direct Lake mode, enhancing performance and simplifying data refresh processes.
• Simplified Management: Minimal setup and automatic scaling allow analysts to focus on insights rather than infrastructure.
• Unified Platform: Access to other Fabric services enables advanced analytics and data science projects without complex data movement.

Final Thoughts

The SQL Database in Microsoft Fabric offers a new approach to data management by unifying operational and analytical workloads.
