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…

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 can deploy it on Linux, Mac OS, and Windows — it's very easy."
"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."
"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 solution is very useful for stock management."
"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."
"Firebird SQL is an open-source solution and can run on most operating systems, such as Linux, Unix, and Windows."
"The benefits of data compression in Oracle Database In-Memory are great because we are using data, and it saves a lot regarding sizing."
"It accelerates query processing, which in turn speeds up operations and streamlines workflow, and ultimately enhancing productivity."
"The Oracle database is easier to program and manage, and is secure."
"Oracle Database In-Memory is a suite of features that improves performance for real-time analytics and mixed workloads."
"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."
"The solution provides a good environment and it's a product we trust."
"The solution's ROI is excellent."
"The most valuable feature of Database In-Memory is that it's really fast."
 

Cons

"On large databases, we have some difficulties."
"Database sharing is a capability that Firebird SQL lacks."
"It would be good to have more automation and integration with the tools from other vendors."
"In the next release, it should support JSON, XML, and replication with third-party tools."
"I'd rate the solution five or six out of ten for the possibilities it has currently."
"It would be interesting if they added functionality with redundancy, reputation, and variability."
"They need to be more reactive and fast. Sometimes, they take too long to resolve some tickets."
"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."
"Multitenant, to be honest, is a little adolescent at this point."
"Oracle Database In-Memory could improve by better supporting generative AI challenges, such as hallucination management."
"The solution should move to the new way of writing software code with AI that is intelligent and learns."
""It depends". If you get a good support engineer, it is a dream. But, most times, it is not, unfortunately."
"The high cost of the product is an area of concern where improvements are required."
"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."
"We often have to find solutions on our own through the support site, so there's room for improvement in this regard."
"It would be good if Oracle could reduce downtime when transferring from non-In-Memory to In-Memory."
 

Pricing and Cost Advice

"The most valuable feature of the solution is that it is freely available."
"It's open-source and free."
"We are using the free solution, so there is no cost involved."

"Database In-Memory is priced a bit higher than its competitors like Microsoft."
"Oracle Database In-Memory is expensive."
"It's quite costly and it comes with a fixed price."
"There is a need to make a yearly payment towards the licensing costs, after which there is any to pay towards the support cost attached to the solution."
