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 data capture optimizes database performance but Views create problems
One of the most valuable features is real-time data capture; it optimizes database performance. I think using real-time data capture reduces job running time and the amount of data sent at once with batch loads. Replicating the same data daily isn't optimal, so real-time reception improves application performance and reduces latency.

Quotes from Members

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

Pros

"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 the solution is that it is reliable, offers good performance, and is easy to use."
"The solution is very useful for stock management."
"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."
"Robustness is the absolutely main feature."
"Firebird SQL is an open-source solution."
"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."
"It is very useful for both structured and unstructured data. You can store unstructured and structured data in PostgreSQL. It is easy to use. You can easily manage things through PostgreSQL Admin. It is cost-effective. Its on-premise version is free. It is agnostic of on-premise or cloud. You can install it on the cloud or on-premises. It is available with all clouds, and you can also install it on desktop or Windows Servers."
"PostgreSQL is very easy to use. I have experience in Oracle SQL and PostgreSQL uses the same syntax which makes it is easy for me to develop."
"The tool is user-friendly."
"We often use PostgreSQL for operations monitoring because we are a manufacturing company."
"The product is easy to use and works fast for relational databases."
"Clustering will be the number 1 feature. It is also open-source so it is free. It can also be clustered, to allow fault tolerance."
"The solution is quite stable."
"The PostgreSQL database is similar to the SQL Server but has a slightly different technology that has similar resources as well. If the customer has the confidence using SQL Server, they will be fairly comfortable using this solution."
 

Cons

"Database sharing is a capability that Firebird SQL lacks."
"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."
"The security of the users could improve in Firebird SQL."
"On large databases, we have some difficulties."
"It would be nice to have a graphical user interface to handle the product."
"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 is not easy to integrate the tool with Visual Studio."
"There could be a plugin to distribute the data on servers for the product."
"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."
"The user interface for the clients could be easier to use as they are small businesses. From a technical support perspective, the documentation could be improved."
"PostgreSQL could improve by adding data warehousing tools."
"The user interface could be a bit better."
"I had some issues when I integrated with the Jupyter Notebook."
"When you get a large number of records in a database and start doing various queries, it can adversely impact the performance of the live running systems. That's an area we continue to look at and mean to improve, but it is not only because of PostgreSQL. It is also because of the way the schemas are put together, and certain events are triggered. So, it is because of both parties."
"PostgreSQL’s performance could be improved."
 

Pricing and Cost Advice

"Firebird SQL is an open-source solution, which means it is a free product."
"The most valuable feature of the solution is that it is freely available."
"It's open-source and free."
"It is a public domain system as every customer can install it on their system without paying any license fee."
"We are using the free solution, so there is no cost involved."
"I was using the free version of Firebird SQL."
"The tool is open source."
"It is okay."
"It is free. There is no license on it."
"It is free, but if you need support, you can go for the commercial version called EnterpriseDB. They provide paid support, and they can even do hosting for you if you want standby and support."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
"We use the open-source version of PostgreSQL and not the enterprise edition."
"We do not pay for licensing."
"PostgreSQL is a free and open-source database."
"The tool is cheaply priced compared to other RDBMS providers in the market."
"We are using the free version of PostgreSQL."
