An open-source database to hold customer data, but its performance should be improved
Firebird SQL significantly improved our data management in many parts of our self-developed ERP system. I rate the solution's performance and speed a six out of ten. Two or three database administrators are needed to maintain the solution. A few years ago, migrating data to or from Firebird SQL was a little bit difficult because the identifier names for tables or stored procedures were limited to 20 to 30 characters. Transferring the structure to Firebird SQL was difficult, but they fixed it in version 3, which was much easier. We are developing software with Delphi, and Delphi is also by Embarcadero. Using InterBase or Firebird SQL databases is very common, and you have some good tools for developing with Firebird SQL. Overall, I rate the solution a seven out of ten.

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

"Robustness is the absolutely main feature."
"The documentation is very well written."
"The most valuable feature of Firebird SQL is the creation of databases."
"The solution is very useful for stock management."
"The most valuable feature of the solution is that it is reliable, offers good performance, and is easy to use."
"I find the ease of deployment to be the most valuable aspect of this solution."
"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."
"The reliability and ease of management are very valuable."
"I like Oracle because it is a backward-compatible solution."
"The most valuable aspects of this solution are the fast caching and improved performance to the database"
"It accelerates query processing, which in turn speeds up operations and streamlines workflow, and ultimately enhancing productivity."
"The solution is very fast."
"We use the tool for real-time data transfer for risk management purposes. In a trading system, conversions happen fast. We use the product to handle fast transactions with low latency."
"The application development is very user-friendly."
"Normally, every database server uses hard disks. In-Memory has a feature, apart from their database, which is very good. When we start our server, all your data needs loading memory. We can use that. It's a very good feature. I think they added this feature in 2019. We can mount memory in the partition, create partitions in there, and create table space from that spot to share. It's a really good feature. We use it a lot."
"We have recently deployed our database on cloud with Oracle Database In-Memory; we have a single standby on cloud, and on contingency occasions, we switch over to cloud and use it for four to five months."
 

Cons

"It is not easy to integrate the tool with Visual Studio."
"On large databases, we have some difficulties."
"It would be good to have more automation and integration with the tools from other vendors."
"The security of the users could improve in Firebird SQL."
"It would be nice to have a graphical user interface to handle the product."
"In the next release, it should support JSON, XML, and replication with third-party tools."
"Database sharing is a capability that Firebird SQL lacks."
"This solution isn't very user-friendly, or intuitive, which could be improved when it is developed."
"The solution is quite expensive."
"The platform’s pricing needs improvement."
"The dashboard requires some refreshment or configuration improvements."
"The solution should move to the new way of writing software code with AI that is intelligent and learns."
"It would be good if Oracle could reduce downtime when transferring from non-In-Memory to In-Memory."
"The product could benefit from enhancements in its graphical user interface."
"The product could be more economical."
"Oracle Database In-Memory could improve by better supporting generative AI challenges, such as hallucination management."
