The product is tied to Transact-SQL (T-SQL), which is an implementation of SQL from Microsoft that adds several proprietary programming extensions to the standard language. SQL Server is built similarly to other RDBMS products, as its structure is a row-based table that connects related data elements in different tables to one another. One of its most important components is the SQL Server Database Engine, as it controls data processing, storage, and security. Beneath the Database Engine is the SQL Server Operating System, which is used for memory and I/O management, locking data to avoid unneeded upgrades, and job scheduling.
The solution has four editions with different sets of services and tools. They include:
The first two are available for free and are typically utilized by smaller companies, as they work with fewer functions and storage. The second two editions are generally used by bigger organizations and enterprises and offer more features.
The solution has several functions through which users can facilitate different data-related processes. These include:

|---|---|---|
| Data Warehouse Lead at Resurs Bank AB (publ.) | 4.0 | I find SQL Server excellent for OLTP/OLAP, particularly its immutable Ledger and seamless Microsoft integrations. However, I believe high availability and disaster recovery features, along with newer functionalities, need significant improvement and continuous development, despite generally good stability and scalability. |
| Manager - Production Database Administration at a tech vendor with 10,001+ employees | 4.5 | I find SQL Server excellent for enterprise database management, appreciating its robust HADR, GUI, and cost-effectiveness. While setup is easy and scalability good, I wish for two-node write capabilities and improved, non-third-party customer support. |
| Subdirector of Support for Production at Servicios Electrónicos Globales -Oficial | 5.0 | I rate SQL Server 10/10 for its stability, availability, and excellent ETL, vital for financial reporting. However, its substantial cost, particularly for high availability, is a major drawback, making me consider alternatives despite positive support. |
| Data engineer at a tech vendor with 10,001+ employees | 4.0 | I value SQL Server for its excellent backup, performance, security, and parallel processing, finding it stable and user-friendly. While licensing and scaling costs are high, its capabilities and support are strong, earning it an 8/10. |
| Infrastructure Coordinator at a financial services firm with 10,001+ employees | 4.0 | I find SQL Server a good, easy-to-use solution with good performance across applications. Setup is simple and ROI is good. However, I believe better integration with other tools like Excel would be an improvement. |
| AVP at MIDDAY INFOMEDIA LIMITED | 4.0 | I use SQL Server for various database tasks, finding it stable, scalable, and secure with good support. Its robust capabilities are great, though pricing and integration could improve. I rate it 9/10. |
| Student at a university with 501-1,000 employees | 4.5 | I use SQL Server daily for .NET development and data management via SSMS and Redgate, appreciating its detailed error messages and time-saving features. While stable and scalable, I'd like more SSMS extensions. It's an essential, time-saving tool for my team. |
