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

"MariaDB has a straightforward initial setup with easy-to-understand documentation."
"It's a very easy product to set up."
"The most valuable feature of the solution is a relational database, which is fairly reliable...It is a stable solution."
"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 a cloud-based tool, so it is pretty fast."
"The most valuable feature is that it uses multiple cores, which is better than some of the other databases."
"What I like best about MariaDB is that it is open-source and reliable."
"This solution is user-friendly."
"The most valuable feature of SQL Server is that it is easy to set up."
"The feature that I have found most valuable is that it is easy to code."
"SQL Server has good performance. It is one of the best features."
"The availability is the most valuable feature. It has high availability. It also has good performance."
"It is integrated with Microsoft tools."
"The solution is easy to set up."
"The latest version supports for big data analytics. SQL Server's vector processing-based batch execution mode is now available to the entire execution of R or Python code. Since much of the work that tends to be done in R and Python involves aggregation, batch mode - which processes rows of data several at a time, can be very helpful."
"Comparing with other database management systems that I tried in other companies, SQL Server is quite easy to install, configure, and maintain."
 

Cons

"Master-master replication is something that needs to be simplified."
"The maintenance and performance could be a bit better."
"There could be a command-line prompt for repairing the database and fixing indexes, similar to what was available in the old MyISAM storage engine."
"In the next release, I would like to see improvements in the scalability and redundancy features."
"The price could be less expensive."
"The product needs more features and more functionality. It's imperative that it supports more platforms, and supports more operating systems."
"We'd like more data intelligence."
"The solution should do some fine-tuning on maybe the transaction per second so that users can get more than they can on the Microsoft SQL Server."
"Additional interfaces would be an improvement."
"The only item which I can list is application failure during Integration Services debugging, when restarting a process flow. In a number of instances the solutions fails. I have not given this much thought and simply stop and start the debugging service rather than restarting."
"The treatment of database storage could be improved."
"They could improve by adding the SQL format."
"I would like to see the performance improved. Migrating should be easier and the scalability needs improvement."
"Security is an area that can be improved."
"In my experience, I've found that scalability can be improved."
"SQL could be improved by making all features available on the on-premise version of the product as well as the cloud version. When you buy the on-premise version, it's sort of an inferior product compared to the cloud version, which seems to get most of the latest and greatest features."
 

Pricing and Cost Advice

"The price could be less expensive."
"MariaDB is an open-source software, meaning I don't need to pay for the product."
"It is free of charge."
"The licensing cost is approximately $4000.00 per year and the licensing is based on the software and the number of posts that you make."
"There is a monthly subscription to use MariaDB."
"This is an open source solution with no licensing fees."
"MariaDB is available for free."
"The tool is open-source."
"The price of SQL Server could be better in the African market. The licensing model needs to be improved, it is confusing."
"​It has the easiest licensing."
"Some of the licensing are very expensive, such as the Enterprise license."
"We're looking at alternative solutions because we think Microsoft's licensing costs have been expensive."
"It is expensive, especially when you have open-source products that are just about as functional and they're free. They might want to consider re-evaluating their pricing. We purchased it in retail. It was somewhere in the neighborhood of 9,000. There is just the standard licensing fee. If they migrate this product the way they're trying to do everything else, eventually, it is going to be subscription-based, which is going to suck, but that's the way the industry is going, so it is what it is."
"Although it comes with a cost, using the most recent version is highly advisable, since it would ensure a certain measure of bug fixes and stability. The sole issue would involve the cost, as this is expensive."
"For medium-sized customers who don't need some enterprise features, the tool would be available for 200 USD per month. For the enterprise segment, the tool's cost can go up to 6,000 USD."
"There is a subscription that needs to be purchased to use the solution."
