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…

Has supported web application data needs but requires design adjustments to manage complex queries efficiently

Complex queries in MariaDB where the query needs to parse thousands of lines or data values face some performance issues. For small and medium-size volume, it is pretty good. If it goes beyond certain data and complex queries, we see performance issues. We tried the advanced replication feature between different regions, replicating data specifically residing on MariaDB to two different regions of MariaDB data, and there were some technical snags in terms of slowness and longer processing time. Point-in-time recovery in MariaDB is good for small databases. When data volume increases beyond 5 GB or 10 GB per day or runs into double-digit GBs, we found some performance issues. For data below 10 GB, it works fine. Performance is the primary focus area for MariaDB, particularly during transactions or complex query jobs where slow performance is observed. MariaDB is scalable and easy to scale.

High-volume transactions have reduced failures and improve customer service efficiency

The best feature is performance, because of which I decided on PostgreSQL. I have also enabled the PG vector plugin on top of PostgreSQL. I have the opportunity to use two different features and two different flavors in a single product, which is the best thing about PostgreSQL. Initially, we had some hiccups around the performance part, but later we did indexing in PostgreSQL and now it is working very well. Even when we are doing 100,000 transactions in a day, PostgreSQL is working excellently. The interface is another best feature. If I need to do any query, I simply install the plugin on my local, which is pgAdmin. Through pgAdmin, I am able to communicate with PostgreSQL and execute all my SQL queries. I am getting a better UI with PostgreSQL as the backend, which is also one of the best options. PG vector is also very strong from PostgreSQL where I have implemented RAG and on a daily basis, I inject thousands of pages of PDF. More than 100 PDFs are coming into my system and one PDF is around 1,000 pages. We are injecting them into PostgreSQL and converting them into dimensions and inserting them into PG vector. The level of transactions we are doing on a daily basis is substantial, and we are getting very good throughput and low latency from PostgreSQL. When we were doing more than 50,000 transactions in a minute with the previous database, we were getting a lot of latency issues with threads getting blocked and abruptly closed unwantedly. After doing extensive research, we decided to move to PostgreSQL. Now, we are doing around 100,000 transactions in PostgreSQL and we are getting good throughput with no 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."

"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."

"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."

"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."

"I can deploy it on Linux, Mac OS, and Windows — it's very easy."

"We are satisfied with Firebird SQL, and we will keep on using it."

"The most valuable feature of Firebird SQL is the creation of databases."

More Firebird SQL pros

"It is a scalable solution. It easily scales up and scales down."

"You get the performance, you get the security, and you get monitoring and disaster recovery."

"From a customer perspective, MariaDB is a good choice for cluster configuration, it's also easy to operate and cheap."

"The price of this solution represents a very good compromise between the cost and what it offers."

"We have seen a return on investment because we are going to save a lot of revenue from not having to use Oracle licenses."

"If you want a reliable, easy to maintain database solution, I think that MariaDB on RedHat/CentOS is an option that every DBA should consider."

"The most valuable feature of MariaDB is the replication mode."

"It's open source."

More MariaDB pros

"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 makes it very adaptable to several descriptions of a record; instead of having several tables or several relations for one entity, I can adapt this entity, and this plasticity allows me to move it for every person that is inside the company."

"By implementing PostgreSQL, organizational databases get stabilized, no locking issues occur and report extraction is faster."

"Because we use it in many information systems (Financial, Human Resources, Inventory Management) in several large companies with significant data flow, we have not had problems."

"We are able to create many different types of jobs and items with this solution making it one of the most valuable features."

"As it's open source the ROI is quick."

"The solution is very easy to use; you don't have to be extremely knowledgeable or technical to take advantage of it, and the product is quite flexible while being one of the cheapest options on the market."

"It is easy to use."

Cons

"This solution isn't very user-friendly, or intuitive, which could be improved when it is developed."

"I'd rate the solution five or six out of ten for the possibilities it has currently."

"On large databases, we have some difficulties."

"It is not easy to integrate the tool with Visual Studio."

"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."

"They need to be more reactive and fast. Sometimes, they take too long to resolve some tickets."

"The solution could improve by providing partitioning and encryption."

"There aren't a lot of people using this solution — it's not very popular in the marketplace."

More Firebird SQL cons

"It would be good if they can maybe improve the mass import in the database."

"The scaling for database online transactions needs improvement."

"We'd like more data intelligence."

"The PL/SQL performance is slow if you have big batch jobs running overnight."

"The maintenance and performance could be a bit better."

"I'd like to see improved materialized views, like the ability to save select queries. This feature is missing in MariaDB compared to other relational databases like Oracle and SQL Server."

"The price could be less expensive."

"I am editing."

More MariaDB cons

"In fact, this could be a risk, because heavily loaded production environments usually needs DBA monitoring and intervention."

"It needs better support for JSON and web services."

"Postgres should focus on building a stronger knowledge base. They also need to expand their integration capabilities, so more tools and resources are available to manage it."

"I'd like to see the following improvements: Streaming replication (or similar) disconnected from the version, so we can use it for upgrades (i.e., a 9.3 version master and a 9.5 slave)."

"Scalability; Although PostgreSQL is known for handling very well large amounts of workload, NoSQL databases performs better when scaling."

"I had some issues when I integrated with the Jupyter Notebook."

"It would be good to have machine learning functionality in this solution, similar to Microsoft SQL Server and other solutions."

"Parallelization and some connection to analytics is needed."

Pricing and Cost Advice

"It is a public domain system as every customer can install it on their system without paying any license fee."

"The most valuable feature of the solution is that it is freely available."

"It's open-source and free."
