Offers robust security and availability with impressive replication capabilities

Regarding their documentation and interface, there is room for improvement. Documentation is definitely required when running multiple databases on a cluster system. The load balancer, MySQL LB, which is used to connect to the application, lacks clear documentation. When there are multiple application servers connecting to the MySQL cluster and going through the MySQL load balancer, the documentation is not user-friendly. It's there, but only technical persons with deep knowledge of the MySQL database can implement it. Most of the community users or ISVs who use MySQL don't have many technical persons or DBA experts, so they face some challenges for the high availability of connecting high available databases from high available applications. That documentation should be simplified.

Reliable transactions and rich features have powered real time collaboration and faster development

PostgreSQL fully supports ACID transactions, including atomicity, consistency, isolation, and durability, which are some of the best features it offers in my experience. It also supports multiple index types, such as B-tree, Gin, Gist, and BRIN, and provides JSON and JSONB support, which is used to query semi-structured data. PostgreSQL uses Multi-Version Concurrency Control, which allows multiple users to read and write simultaneously. For extensibility, PostgreSQL allows extensions such as PostGIS and pg_trgm, which are truly useful. PostgreSQL improves reliability, performance, and scalability in production. Since it is ACID compliant, it ensures that database transactions are safe and consistent, preventing partial data updates, maintaining data integrity, and allowing multiple users to read or write data simultaneously using MVCC. Features such as foreign keys, constraints, and triggers impact data consistency by preventing invalid data. It supports read replicas, partitioning, and horizontal scaling for scalability. PostgreSQL has been very stable in my experience, handling concurrent requests reliably while maintaining data consistency with ACID transactions and accommodating concurrent users with strong data integrity, making it mature and widely used in production systems. Using PostgreSQL with Prisma allows faster development because schema migrations are automated and type-safe queries reduce the time I spend fixing database bugs, allowing me to focus more on building features while improving collaboration between developers due to a well-defined relational schema. Migration tools keep everyone's database schema synchronized, which allows multiple developers to work on backend features without conflicts. It has a rich feature set, supporting advanced features such as window functions, common table expressions (CTEs), and full-text search, with the flexibility of supporting both JSON and relational data, meaning it can behave as both a relational database and a document database. Extensibility allows PostgreSQL to add new capabilities while maintaining a strong ecosystem that integrates easily with modern backend stacks such as Node.js, Docker, and Prisma.

Quotes from Members

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

Pros

"The product was easy to use."

"The most valuable feature of Firebird SQL is the creation of databases."

"The documentation is very well written."

"I find the ease of deployment to be the most valuable aspect of this solution."

"I can deploy it on Linux, Mac OS, and Windows — it's very easy."

"The most valuable feature of the solution is that it is reliable, offers good performance, and is easy to use."

"It helps us in detecting all kinds of problems in the code, such as bad quality, unclear code, or any violation in the code or best practices."

"I find the ease of deployment to be the most valuable aspect of this solution."

More Firebird SQL pros

"MySQL is easy to use, has fast performance, and it is comfortable for end-user to use. The schema level and structure we are using are very simple and easy to understand. Additionally, packaging tool development is straightforward and the data is presented in a way that is very simple to understand."

"It's a good tool, a good database platform."

"MySQL is a light database. It's not very complex. It's easy to develop, easy to maintain, and easy to back up and restore."

"The solution is a small application and is very easy to deploy."

"It is a stable solution."

"The most valuable feature of MySQL is its reliability and performance."

"The large user base and the amount of available plugins and modules."

"It has a remote access feature to manage the database from a remote location. This enables in-work collaboration."

More MySQL pros

"PostgreSQL is an open source database engine that is very powerful, highly configurable, and more flexible than MySQL or MariaDB because you can create several databases with many schemas and define roles like owners, not only grants over tables or procedures."

"If you have PostgreSQL expertise you can run your business off PostgreSQL."

"PostgreSQL is far more robust and mature than MySQL, especially when you think about keys and indexes."

"It is easy to use."

"This is an open-source solution, operates at a high speed, and supports more than one SQL language."

"Currently this is one of the best solutions on the market."

"I would say that the combination of PostgreSQL's features, plus the reliability and performance it offers in combination with the fact that you don't pay for a license was the reason I chose it."

"It is cost-effective, its on-premise version is free, it is agnostic of on-premise or cloud, you can install it on the cloud or on-premises, it is available with all clouds, and you can also install it on desktop or Windows Servers."

Cons

"The solution could improve by providing partitioning and encryption. It is not at the higher level of database solution but it could be with some upgrades."

"The solution could improve by providing partitioning and encryption."

"It would be interesting if they added functionality with redundancy, reputation, and variability."

"It would be nice to have a graphical user interface to handle the product."

"Technical support and performance could be better. We have some problems with this solution, but we don't know if the problem is with the database or the configuration. For example, sometimes, the users can't access the database."

"The main feature I expect is to be able to work with different databases at the same time because that's a wishlist item for me."

"I don't think the solution is very scalable because the scalability of the performance when using more than one process is not very good."

"There aren't a lot of people using this solution — it's not very popular in the marketplace."

More Firebird SQL cons

"It could be more secure."

"I would like to have features that allow us to jump between the cloud and our on-premises system."

"I haven't really looked into the security of it, but it should be good. It could be more secure."

"It can have better monitoring. In addition, the enterprise manager should be able to cater to more than one virtual machine."

"Oracle should start putting in some of the enterprise features in the standard version. There are some key features that should be part of the standard."

"I find the Microsoft solution a bit better. But mostly in terms of the UI layout, I would say. I just find it a little bit more efficient."

"The work bench has some bugs that are mostly GUI related."

"As an open-source product, there isn't really any technical support available if you get into trouble or have issues."

More MySQL cons

"The scalability is limited."

"Better SELECT performance is something that PostgreSQL could really benefit from."

"JSON support although great, it still has some gotchas, querying and manipulating JSON will be one of the topics I'd like to see some improvement, still feels not natural to work with it."

"It was a bit complex to setup, although I think this was due to ignorance on the project."

"PostgreSQL uses high memory compared to its counterparts when a highly demanding load is involved, especially one that makes many concurrent connections to the database."

"The pricing could be better."

"Sometimes, the views create problems. If you don't have the view, sometimes what happens is you need to have the drivers properly set up for PostgreSQL."

"The pricing could be better."

Pricing and Cost Advice

"It's open-source and free."

"Firebird SQL is an open-source solution, which means it is a free product."

"There is no licensing cost for this solution, as it is open-source."

"The tool is open source."

"It is okay."

"I was using the free version of Firebird SQL."

"There is a yearly maintenance fee for the use of the solution."

"We are using the free solution, so there is no cost involved."

More Firebird SQL pricing and cost advice

"We are using the licensed version of MySQL."

"It is open source. We prefer it for POCs because it saves the license cost."

"There is not a license required for this solution."

"We pay a yearly subscription fee."

"We've never bought a commercial license. We just use the open-source community edition."

"The solution is open source so is free."

"My company uses MySQL's corporate licenses."

"Microsoft licensing for SQL Server is probably ten times more expensive. I used to work for the government, and I remember when we were looking into upgrading to the enterprise version of SQL Server 2019, the licensing was going to cost 350,000. To get the equivalent in the cloud, it was going to be about four grand to get the same processing power and everything else. With MySQL, it was going to be about 300 for the same licensing. Cost-wise, for sure, there is a huge difference. Would you prefer to pay 300 a month or 3,000 to have the same amount of data resources? You might lose a few options that you need, but it isn't worth the price difference."

More MySQL pricing and cost advice

"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."

"It is also open-source so it is free."

"The tool is cheaply priced compared to other RDBMS providers in the market."

"The solution requires a license."

"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."

"The community version of Postgre is basically free."

"PostgreSQL is a free and open-source database."

"Affordable solution."
