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

"Robustness is the absolutely main feature."
"The reliability and ease of management are very valuable."
"The most valuable feature of Firebird SQL is the creation of databases."
"I can deploy it on Linux, Mac OS, and Windows — it's very easy."
"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 solution is very useful for stock management."
"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 most valuable feature of the solution is that it is reliable, offers good performance, and is easy to use."
"I find the performance features of Oracle Database In-Memory to be most beneficial, with system performance in milliseconds, dual format architecture positively impacting our data processing, and clear financial benefits from its efficient operation that improve our overall operational efficiency."
"Oracle is the best database, but I love open-source software."
"I find the performance features of Oracle Database In-Memory to be most beneficial."
"I like Oracle because it is a backward-compatible solution."
"The solution's most valuable feature is its performance optimization within our hardware environment."
"The product offers high scalability."
"The most valuable aspects of this solution are the fast caching and improved performance to the database."
"We find the dashboard and the speed of data processing very valuable in Oracle Database In-Memory."
 

Cons

"It is not easy to integrate the tool with Visual Studio."
"There aren't a lot of people using this solution — it's not very popular in the marketplace."
"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."
"We would like to improve the management of very large databases."
"This solution isn't very user-friendly, or intuitive, which could be improved when it is developed."
"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."
"I'd rate the solution five or six out of ten for the possibilities it has currently."
"Firebird SQL's performance has slowed since Firebird SQL 3 or 3.5 versions, where they developed over-the-wire encryption."
"Multitenant, to be honest, is a little adolescent at this point."
"We have a very large table and a low dose. It is very expensive in data to load all of them into In-Memory. It takes up more memory slots in the server, as well as a lot of RAM."
"I do not see any return on investment or any cost reductions after implementing it."
"Technical support is below our expectations currently. It could be improved."
"The platform’s pricing needs improvement."
"It would be good if Oracle could reduce downtime when transferring from non-In-Memory to In-Memory."
"The product could be more economical."
"The area where improvement is required the most in the product is the UI."
