Nicolae Ancuta - PeerSpot reviewer
Strong event capabilities, allowing raising and displaying events in applications
On large databases, we have some difficulties. It is one of the areas of improvement. For example, under one gigabyte, it works perfectly. Between one and five gigabytes, you might experience some slight performance issues, but they are not significant. Beyond that, you have to index it, tier it, and perform some restore operations to free up space. It requires some effort, but it's manageable. It's quite challenging for the customer. Moreover, migrating from one firewall solution to another was a little bit difficult regarding the backup and restoring the other one. Since we have many databases, we didn't go forward with the latest versions.
PavithrarajShetty - PeerSpot reviewer
Offers simplicity and is cheaply priced
I haven't gone through the scalability aspect since I was using MySQL Server. I haven't worked to a high level in PostgreSQL, but with MySQL Server, I have managed clustering and partitioning. I think I haven't put much focus on PostgreSQL, so I am not sure how it behaves or how it works.

Quotes from Members

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

Pros

"The most valuable feature of the solution is that it is reliable, offers good performance, and is easy to use."
"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 reliability and ease of management are very valuable."
"We are happy with the event capabilities of Firebird SQL database. We can raise events from it and display them in our application."
"The most valuable feature of Firebird SQL is the creation of databases."
"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 can deploy it on Linux, Mac OS, and Windows — it's very easy."
"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 product's deployment is easy."
"What I like is that it's quite powerful in terms of performance."
"The solution is open-source and free to use."
"The built-in code procedural language is the most valuable. It has a built-in layer for code procedures. Its installation is very easy and quick, and it is free. It is also stable, and its performance is also good."
"I like that you can move any relational database from Oracle to PostgreSQL. I also like that it's pretty stable."
"The performance is good."
"We are able to create many different types of jobs and items with this solution making it one of the most valuable features."
"We use the solution to store tables. It is stable and performs well."
 

Cons

"This solution isn't very user-friendly, or intuitive, which could be improved when it is developed."
"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."
"The solution could improve by providing partitioning and encryption. It is not at the higher level of database solution but it could be with some upgrades."
"It would be good to have more automation and integration with the tools from other vendors."
"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."
"In the next release, it should support JSON, XML, and replication with third-party tools."
"It is not easy to integrate the tool with Visual Studio."
"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."
"It is possible that in the newer version this has been addressed, but I would like the deployment in microservices architecture could be improved."
"I find it difficult to get connectors on the tool. For example, .NET has only one free provider in PostgreSQL. I need to pay the provider if I need something more sophisticated features. Other languages like PHP and Java have good community support. We need community support for .NET."
"The performance of PostgreSQL could improve."
"PostgreSQL uses high memory compared to its counterparts when a highly demanding load is involved, especially one that makes many concurrent connections to the database."
"Sometimes, it becomes slow because of the network. So, there is room for improvement in performance."
"There are several features I would like to improve that aren't working as expected. It's likely that the latest version is doing something that was missed in the previous versions. For example, the output parameters — the stored procedures — is something new in PostgreSQL that Firebird has already had for a long time."
"They need to have a better graphical interface. There is a tool called pgAdmin 4 that they use, which is free. It is written in Java, and it is slow. They need to have a better product that is similar to Toad for Oracle, but, of course, it is hard to get something that's really great and free. Other than that, it is great."
"The solution needs to improve the query, documentation, and JSON data functionality."
 

Pricing and Cost Advice

"It is a public domain system as every customer can install it on their system without paying any license fee."
"There is a yearly maintenance fee for the use of the solution."
"The most valuable feature of the solution is that it is freely available."
"There is no licensing cost for this solution, as it is open-source."
"It is okay."
"The tool is open source."
"I was using the free version of Firebird SQL."
"We are using the free solution, so there is no cost involved."
"It is free. There is no license on it."
"The solution requires a license."
"There is an annual license."
"The community version of Postgre is basically free."
"PostgreSQL is a free and open-source database."
"We do not pay for licensing."
"We use the open-source version of PostgreSQL and not the enterprise edition."
"It is open-source. If you use it on-premise, it is free. It also has enterprise or commercial versions. If you go for the cloud version, there will be a cost, but it is lower than Oracle or Microsoft."
