Efficient data storage with reliable and easy management
We are working on monitoring software that involves making a lot of measurements with sensors. We store all the data in Firebird, which is why we use It primarily for data storage It's difficult to describe how it has improved our organization because we have been using Firebird for a very long…

Technical Solution Architect at Vodafone
Real-time analytics have transformed response times and support huge data volumes with compression
I do not have any comment related to the improvement of the solution; for sure, it needs improvement, but for my use cases, it is very sufficient, and I think for the biggest companies, it needs a very powerful infrastructure. The area where improvement is required the most in the product is the UI. The problem with the UI is that it is not complex for understanding, but it needs some training to know what each button does, how it works, and the many variables needed.

Quotes from Members

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

Pros

"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."
"Firebird SQL is an open-source solution and can run on most operating systems, such as Linux, Unix, and Windows."
"The reliability and ease of management are very valuable."
"I like Firebird because it's very lightweight; it's very light and powerful, and I can do everything that I can with MS SQL Server and Oracle with Firebird, with very easy deployment on Linux, Mac OS, and Windows and great integration capabilities."
"The documentation is very well written."
"Robustness is the absolutely main feature."
"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."
"The most valuable feature of Firebird SQL is the creation of databases."
"Oracle Database In-Memory is a suite of features that improves performance for real-time analytics and mixed workloads."
"The most valuable aspects of this solution are the fast caching and improved performance to the database."
"I find the performance features of Oracle Database In-Memory to be most beneficial."
"The scalability of the solution is very good, and it's able to support large amounts of data once the architecture is in place."
"After we started using the in-memory product, we saw really dramatic figures."
"The on-premise version is stable. We have different teams and resources for the server side, for admin, and for development. We can easily take care of all the services and applications."
"The application development is very user-friendly."
"The warehouse is the solution's most valuable aspect."
 

Cons

"The security of the users could improve in Firebird SQL."
"Database sharing is a capability that Firebird SQL lacks."
"It is not easy to integrate the tool with Visual Studio."
"We would like to improve the management of very large databases."
"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."
"Firebird SQL's performance has slowed since Firebird SQL 3 or 3.5 versions, where they developed over-the-wire encryption."
"I'd rate the solution five or six out of ten for the possibilities it has currently."
"For some reason, the stats optimizer doesn't work well. We had to disable some of the Oracle’s new features that are not quite mature."
"The area where improvement is required the most in the product is the UI."
"The solution is very expensive."
"Technical support is below our expectations currently. It could be improved."
"The pricing could be improved. It would ideal if it was more reasonable."
"I do not see any return on investment or any cost reductions after implementing it."
"The product could benefit from enhancements in its graphical user interface."
"In the next release, Oracle should include column store or advanced query optimization so a database can be optimized by enabling analytic queries to run faster."
