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

The solution works fine. The documentation is very well written. It has helped me a lot. I've built a small program to manage the condominium I live in. It is being updated by people who seem to be very interested in making it a first-class tool. I've seen it improve over time since I've been using it.

We are happy with the event capabilities of Firebird SQL database. We can raise events from it and display them in our application.

We are also happy about the transactional features of the database. Moreover, it is pretty easy to maintain, but in some cases, when dealing with a large amount of data, up to 15 gigabytes, it is a little slow. Maintaining the database becomes harder. 

However, if we use it within a comfortable database size, we are very satisfied because we are employing it in a non-critical but twenty-four-hour solution. So, overall, we are pretty happy with it.

Robustness is the absolutely main feature. However, cryptography isn't Firebird's strongest area. While the latest version has built-in cryptography, we're using version 3, which doesn't. It's a valuable feature in the newer versions.

We chose InterBase for our main database around 20 years ago. InterBase is a proprietary software by Embarcadero. Firebird SQL is an open-source solution. Firebird SQL is very similar to InterBase, and we wanted to choose an open-source solution. Transferring data from InterBase to Firebird SQL eight to ten years ago was easy.

The product was easy to use. We didn’t have any problems with maintenance. We had only one or two problems with the database the whole time, but we could restart it. It didn't need a lot of resources. It performed well.

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

I appreciate the fact that, once the database is embedded, it doesn't need to be administered, and removes the requirement for a specific server.

I like that we don't have to pay external fees to migrate this data. So, we are looking to relocate from Postgres or EDB.

The solution is very useful for stock management.

The solution has worked perfectly; I've never run into issues or had to reach out to technical support for troubleshooting.

Firebird SQL is an open-source solution and can run on most operating systems, such as Linux, Unix, and Windows.

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. 

I like Firebird because it's very lightweight. It's very light and powerful. I can do everything that I can with MS SQL Server, and Oracle — I can do the same things with Firebird. It has some very interesting features. For example, I can update and insert with one statement. The deployment is very easy. I can deploy it on Linux, Mac OS, and Windows — it's very easy. 

Also, the integration capabilities are great.
