Has offered a cost-effective option despite frequent technical issues and limited market demand
We find some bugs in IBM Informix. Maybe we are using it more aggressively than others. Every month or every second month, we find some bugs in it, which is not ideal. It should be rare, not this frequent. The good thing is they cover those bugs in the next release within weeks or days on demand. IBM Informix should become hybrid and should include AI features similar to other DBMS systems such as Snowflake, Redshift, and DataBricks. This would help its value rise with the market.

Careful data design has delivered consistent transactions and supports reliable microservices
MySQL is a reliable and mature relational database, but there are a few areas where it could be improved. One area is horizontal scalability. While MySQL supports scaling for applications, handling write-heavy workloads often requires additional solutions such as sharding, which adds complexity. Another area where it could improve is in native support for advanced analytics and large-scale distributed processing, which may require specialized databases. Changing the database schema on large tables can also be challenging and may require careful planning to minimize downtime. Performance tuning is powerful, but identifying and optimizing slow queries often requires manual analysis and experience. Having more built-in performance insights and automated optimization recommendations would be helpful for administrators. In terms of documentation and security, I think MySQL could be improved in those areas. While the official documentation is comprehensive, it can sometimes be difficult for beginners to navigate, especially for advanced topics such as application partitioning and query optimization. More practical examples and architecture-focused guides would be beneficial. On the integration side, MySQL already works well with frameworks such as Spring Boot and Hibernate, but enhancing support for modern cloud-native deployments, Kubernetes, and automated observability would simplify operations. MySQL is a mature and dependable database, and I hope to see improvements primarily around administration, better operational tooling, and a smoother developer experience rather than fundamental database capabilities.

Quotes from Members

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

Pros

"It supports in-house-built applications in .NET and VB6"
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"OLTP processing capacity and the availability of information with high availability implementation have been significantly improved."
"Informix can support huge quantities of data with less memory and less capacity."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"Not looking at Informix would really mean a shot in your own leg before walking a long distance."
"My advice is to take it; you will never regret it."
"It supports multiple applications and business intelligence tools."
"MySQL has improved our internal procedures by providing high performance, ease of use, and cost savings."
"The tool is open-source and there is no cost involved in its use."
"The relations in the database, the dynamic workflow, and the ability to connect with all columns. It's useful for e-commerce."
"It's a good tool, a good database platform."
"The solution is easy to use."
"I would use MySQL for a medium project, with around 1,00,000 hundred thousand users, because of the indexing and stored procedures."
"The large user base and the amount of available plugins and modules."
"This database enabled us to web present our content in a cost efficient way."
 

Cons

"I really would love to have a QT plugin."
"The product needs a lot more marketing involvement from IBM."
"Informix is very sturdy, but the problem for us is the marketing action around Informix."
"This product could be made easier to use for beginners."
"The solution lacks some functionality."
"In my opinion, the packages could be improved. The version I use doesn't allow for packages. I can do some general procedures, but no packages like in Oracle. So, develop separate modules in SQL language. This would be most beneficial for me."
"For me, it's always too expensive. The problem is that Informix sometimes competes with free products, so yes, it's very expensive, but when we're talking about licensed products like SQL Server or anything, the midsize pricing could be significantly improved."
"This solution is in need of more current tools."
"With time, we got version issues, as our DB engine was so old and not updated."
"Sometimes, although your server is configured properly, you might experience a slow performance, especially on a shared hosting server."
"While utilizing a comparable algorithm, is noted to be sensitive, especially when configuring the inner device."
"When working with a cluster wide, I have to use the MySQL cluster version."
"The GUI interface probably can be improved. Let us say I want to see the relationships in the database. In the query analyzer, I would like to go and drop the tables and create relationships between the tables. I haven't found a feature like that in MySQL. It was a shortcoming even in SQL Server. MySQL can have more performance monitoring tools. I know Google has these tools, but within MySQL, there are not that many tools to monitor things like performance and database locking. They might be in there, and I might not be familiar enough to know where they are. I am a pretty new user of MySQL."
"Replication and HA features, but that is to be expected at this entry point."
"We switched to a different solution because of data access issues, speed, and consistency."
"The availability of tools could be improved in the MySQL open-source platform. They can provide more analytical tools. I haven't had any particularly difficult issues to troubleshoot on MySQL, but in the past, on Microsoft SQL Server, I had to troubleshoot some difficult issues, and better tools were in place to see what was going on in real-time on the server. So, that's the bit that is lacking on the MySQL open-source platform."
 

Pricing and Cost Advice

"For me, it's always too expensive."
"The free edition can be enough to handle moderate-size implementations, but you may want a pay for edition to benefit from more functionality, such as replication."
"I am not aware of the licensing costs or terms."
"The product has reasonable pricing. We purchase its yearly license."
"I am using the Community Edition, which is available free of charge."
"There is a license needed for this solution."
"The tool is open source."
"Can range from free to quite expensive, depending on the environments and requirements, so better to really set goals ahead of setting it up."
"MySQL is very cheap. It could be free. It also has a yearly licensing option."
"The tool is open source."
"There is no licensing fee."
"The pricing is not much expensive, it's cheap."
