Executive SummaryUpdated on Apr 20, 2025

SQL Server and MariaDB compete in the database management systems category. Based on the data, SQL Server seems to have the upper hand due to its extensive features and reliability, despite its higher costs compared to the open-source model of MariaDB.

Features: SQL Server offers high availability, scalability, and user-friendliness. It integrates seamlessly with cloud services and supports easy setup and deployment. MariaDB is valued for being open-source, stable, and cost-effective, offering strong performance in complex relationships, columnar queries, and flexibility.

Room for Improvement: SQL Server could enhance integration with other platforms and improve its indexing and performance tools. The cost can be a barrier for small businesses. MariaDB should enhance its error handling, clustering, and replication capabilities. Better support for large-scale transactions and broader integration tools would be an improvement.

Ease of Deployment and Customer Service: SQL Server is versatile across on-premises, hybrid, and cloud environments with generally satisfactory Microsoft support, varying by issue complexity. MariaDB excels in on-premises and hybrid setups, relying on community-based troubleshooting due to limited corporate support, which poses challenges in complex deployments.

Pricing and ROI: SQL Server has high enterprise licensing fees but provides good ROI through its features and performance, with manageable costs in smaller setups. Conversely, MariaDB leverages a free open-source model, offering cost savings and quicker ROI, especially appealing to budget-conscious users who do not need extensive service support.

Easy to deploy, cost-effective, and integrates seamlessly with other products

We had planned for an RDBMS version and not NoSQL. We use MariaDB Galera Cluster. It's a good product. It is cheap, scalable, performs well, and is efficient. We use GCP’s BigQuery for machine learning. We must follow the best practices of the tool. We missed some best practices like the storage engine and InnoDB. It was very difficult to identify why we were having performance issues. Then, we realized that some of our tables were still on MyISAM, the default storage engine. When we switched it back to the InnoDB, it was very smooth. InnoDB is the recommended one. We must follow the best practices given in the documentation during the initial setup. Overall, I rate the product a nine out of ten.

Helps monitor queries and identify which indexes need to be created in the databases

SQL Server is very simple due to its GUI, which is available for users. It allows for modifications and has execution plans available, along with options such as activity monitoring. This helps monitor queries and identify which indexes need to be created in the databases, tables, or columns to improve performance.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"We use MariaDB for identity provider services. Most of the things that we are doing are deployed in the container mode. All such solutions require a database, and MariaDB is easier to use for these kinds of deployments."

"The most valuable features of the solution stem from the fact that it is an open-source product and offers its users great online community support."

"I would say that for most use cases it works fine."

"The solution is very stable. It was originally built under MySQL. It has a similar level of stability."

"The stability of MariaDB is good, it has high availability."

"The performance is very good."

"It's easy to set up."

"Installation is straightforward."

More MariaDB pros

"The solution has proven to be very stable."

"The most valuable feature would most likely be querying. We query a lot, we use a lot of stored procedures. As for other features, such as replication and all other more fancy features we don't use them the most. I do not know, but perhaps the DBAs would be the best people who know of the features that they use, but as far as how I use it, it's just for querying and running stored procedures. We use the bare minimum features."

"Similar to Microsoft SQL, it is easy to scale."

"Enables us to convert to bigger DBs and more easily move or upgrade between branches."

"The documentation and manuals are very good."

"The columnstore index feature is useful for us, and we also use the integration services. It is also very stable."

"SQL Server is a stable product."

"I have found the most valuable features to be the flexibility and the vast amount of features available."

More SQL Server pros

Cons

"The license should be cheaper and closer to that offered by MySQL, Oracle and other products."

"The only potential area for improvement could be the pricing model, which might benefit from being more flexible or a bit cheaper."

"Data continuity could be improved."

"The difficult part related to the product stems not from the tool itself but is related to learning how to implement the product in the right way without creating any wrong configuration that could cause security issues or performance issues."

"I’m not sure if it can scale."

"It would be helpful if I could specify multiple drives for the database storage."

"The features available are very basic."

"The dashboard and pricing need improvement."

More MariaDB cons

"The solution is rather expensive."

"I would like the SQL Server to be able to provide cloud support. We use the solution with a Korean provider supporting only MySQL rather than Microsoft SQL Server, which would be preferable and cheaper. This would prevent us from having to pay for troubleshooting and hosting the server."

"The ability to connect with other environments needs to be improved."

"The user interface and the reporting could also be improved."

"I would like to see improvements made to the stability of SQL Server, as well as more analytics requirements."

"The solution could be better when it comes to security."

"Sometimes the system hangs. Its databases should be able to deal with more data in a faster way. Its speed of processing larger amounts of information should be improved."

"The performance is not always the best."

More SQL Server cons

Pricing and Cost Advice

"My company uses the free version of the solution."

"The price could be less expensive."

"The solution is free, but if you want the enterprise version you will need to pay for some licenses but the cost is less than other solutions, such as Oracle."

"MariaDB is available for free."

"It's an open-source solution."

"MariaDB is a free-to-use solution."

"The cost is quite good. You can have the open source, free version, which has adequate capacity."

"I rate the product's price a three on a scale of one to ten, where one is low price, and ten is high price since there are some support costs involved, even though it isn't an open-source solution."

More MariaDB pricing and cost advice

"I don't need a license for it as I will be migrating to Office 365."

"The price of SQL Server could be reduced, the license is expensive. We have an annual subscription."

"It is something we have been using for a lot of years. If we're paying, it should be reasonable."

"This is a downside of enterprise Microsoft products."

"The price of the solution is fine."

"The price has been going higher and higher. The market is quite price sensitive."

"There is a license required for this solution."

"The setup cost is high, but it will return every penny."

Overview

MariaDB is an open source relational database created by the original founders of MySQL. It is considered one of the most popular and trusted database servers throughout the world. MariaDB is a valued component found in most cloud offerings and is the default in many Linux tools. It is also widely used by Wikipedia, WordPress, and Google, among other well-known sites. Maria DB easily melds data into concise information from a vast array of applications, such as banking, online shopping, websites, and more.

MariaDB was originally created to improve MySQL performance. It is the most widely chosen database server due to the solution being super fast, robust, user-friendly, and easily scalable. MariaDB also offers a substantial ecosystem of plugins, storage engines, and numerous other valuable tools that make it very attractive for a significant offering of use cases.

The solution’s newest functionalities include compatibility with Oracle Database and Temporal Data Tables, and advanced clustering with Galera Cluster 4, which make it easier for users to research data history from any point in the past. Additionally, the most recent versions include JSON and GIS features. MariaDB is committed to staying an open source solution.

MariaDB Features

More storage: MariaDB works with more storage engines than MySQL and most other database servers available. Some storage options include, but are not limited to ARCHIVE, MERGE, CSV, MEMORY, BLACKHOLE, MyISAM, ColumnStore, MyRocks, and Cassandra.
Super fast: MariaDB offers faster authentication checks. The FlushSSL permits SSL certificates to be reloaded without a server restart, resulting in huge time savings.
Improved testing: MariaDB offers an extending testing suite that runs faster and can test more than ever before. Bugs can be easily fixed and invalid tests removed.
Genuinely open source: Every code in MariaDB is GPL, LGPL, or BSD. Client libraries [for Windows (ODBC), Java (JDBC), or C] allow linking to closed source software. All fixed bug cases and development plans are completely public. MariaDB is a community-developed solution representing the true spirit of open source products.

Reviews from Real Users

Faustine C., Engineering Supervisor- Corporate Data Solutions and Services at TZ Telecoms Corporation, shares, “The software provides a lot of information on what is happening inside the database. For most performance parameters it is easy to know if something is not right in the configuration or optimization which helps engineers take remedial fine-tuning measures. For example, if the database is underperforming it is easy to know which performance parameter can be adjusted to handle the workload. It is difficult to troubleshoot database issues if many performance parameters can not be monitored or debugged which is the case with some database management systems. It provides great monitoring of data storage, processing, and performance stability which is really important for real-time data storage and processing. It's a user-friendly product.”

A PeerSpot user who is a Senior Engineer at a tech services company relates, “ The solution's high availability is its most valuable aspect. We have found the product to be stable and the initial setup is pretty simple. I'd rate the solution at a ten out of ten. I'm very happy with it overall. I would recommend the solution to others. It's easy to find details about the product online and to learn about it.”

MariaDB

SQL Server is a relational database management system (RDBMS) by Microsoft. The product's main purposes are to store data and retrieve it as requested by other software applications - on the same computer or on another computer across a shared network. The solution is built on top of Structured Query Language (SQL), which is a standardized programming language used for relational database management.

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:

SQL Server Developer
SQL Server Expression
SQL Server Standard
SQL Server Enterprise

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:

Aggregate functions: These functions are used to calculate one or more values and return a single value.
Window functions: Window functions calculate an aggregate value based on a group of rows and return multiple rows for each involved group.
Date functions: These functions allow clients to handle data and time data efficiently.
String functions: Through the string functions, SQL Server processes an input string and returns a string or numeric value.
System functions: The system functions of the product return objects, values, and settings.

SQL Server Services

SQL Server has a wide range of add-on services that provide additional benefits beyond database management. These services include:

Machine learning: SQL Server machine learning services allow users to do machine learning and data analytics within the product.
Service broker: This feature is a part of the database engine and offers messaging and message queuing for applications on the platform.
Replication: This feature consists of transaction replication, merge replication, and snapshot replication.
Analysis: SQL Server Analysis Services (SSAS) adds online analytical processing (OLAP) and data mining capabilities to SQL Server databases.
Reporting: This feature supports the development of custom reporting applications.
Notifications: This feature generates data-driven notifications which are sent to subscribers of Notification Services.
Integration: This SQL Server feature provides capabilities for data integration, data import, and data warehousing.
Full-text search: Through this feature, users can utilize specialized indexing and query for unstructured text stored in the solution.
Visual studio: This feature supports data programming with SQL Server.
Azure Data Studio: This is a cross-platform query editor that can be downloaded and used alongside SQL Server.

SQL Server Benefits

The solution has many benefits for users. These include the following:

The platform ensures a consistent experience across other platforms while being fast and agile.
Through the built-in intelligence features, users can understand their data better.
The solution has enterprise-level security, which ensures the smooth and safe performance of users' data.
SQL Server offers the ability to retrieve large amounts of data quickly and efficiently.
The product installation process is fairly easy, and it offers a user-friendly interface.
SQL Server offers improved data storage and retrieval functions through frequent upgrades.
The solution reduces the risk of database server attacks, since it is not an open-source database.

Reviews from Real Users

A president at a consultancy evaluates SQL Server as a veteran solution with critical log shipping feature.

Harkamal S., a user at a manufacturing company, rates SQL Server with a high mark because it is a stable, scalable, and easy-to-deploy solution that pretty much covers everything.
