Synapse SQL vs MS SQL Server: A Comprehensive Comparison

Both Synapse SQL and MS SQL Server are powerful database solutions offered by Microsoft, but they serve different purposes and have distinct features. In this article, we will delve into the key differences between Synapse SQL and MS SQL Server to understand their strengths and use cases.

1. Purpose and Workload

Synapse SQL is part of Microsoft Azure Synapse Analytics and is designed for big data analytics, data warehousing, and handling large-scale analytical workloads. It excels in processing and analyzing massive datasets to derive valuable insights for data-driven businesses.

On the other hand, MS SQL Server is primarily designed for traditional transactional processing. It is a general-purpose relational database management system (RDBMS) widely used for OLTP (Online Transaction Processing) applications.

2. Scalability and Architecture

Synapse SQL utilizes a Massively Parallel Processing (MPP) architecture, where queries are distributed and processed across multiple nodes, allowing for seamless scaling of compute resources. This enables Synapse SQL to handle massive datasets and deliver high-performance analytics.

MS SQL Server's scalability is limited to the resources available on a single server. While it supports horizontal scaling through database replication and sharding, it may not be as efficient as Synapse SQL when dealing with very large datasets and complex analytical workloads.

3. Data Storage and Formats

MS SQL Server stores data in a traditional row-based format, which is well-suited for transactional processing and ensures data consistency. However, it may not be as efficient for analytical queries on large datasets.

Synapse SQL, on the other hand, can store data in a columnar format, which provides better compression and faster aggregations. This makes it more efficient for analytical queries as it reduces the amount of data read during query execution.

4. Integration with Azure Services

Synapse SQL seamlessly integrates with other Azure services, such as Azure Data Lake Storage, Azure Data Factory, and Power BI. This integration allows for end-to-end data analytics solutions and simplified data movement and visualization.

While MS SQL Server can also integrate with Azure services, it may require additional configuration and development effort to achieve the same level of integration as Synapse SQL.

5. Security and Compliance

Synapse SQL provides robust security features, including data encryption, role-based access control, and Azure Active Directory integration. It also complies with industry standards and regulations, making it suitable for enterprises with stringent security and compliance requirements.

MS SQL Server also offers strong security features, but the level of integration and native compliance support may not be as comprehensive as Synapse SQL.

6. Use Cases

Synapse SQL is an excellent choice for organizations that deal with vast amounts of data and require advanced analytical capabilities. It is ideal for data warehousing, big data integration, complex querying, and business intelligence.

MS SQL Server is better suited for transactional applications and general-purpose databases where data is structured and consistent. It is widely used for enterprise applications, content management systems, and traditional OLTP scenarios.


In conclusion, both Synapse SQL and MS SQL Server are powerful database solutions, each with its own strengths and use cases. Synapse SQL is tailored for big data analytics and data warehousing, with a focus on high-performance analytical workloads. On the other hand, MS SQL Server is a versatile RDBMS optimized for transactional processing and general-purpose databases.

Choosing the right solution depends on the specific requirements of the project, the size of the dataset, the complexity of the workload, and the level of integration with other Azure services. Both platforms are valuable in their respective domains and play a critical role in the Microsoft data ecosystem.
