Nasir Niamat - PeerSpot reviewer
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.
Prabir Kumar Kundu - PeerSpot reviewer
Offers robust security and availability with impressive replication capabilities
Regarding their documentation and interface, there is room for improvement. Documentation is definitely required when running multiple databases on a cluster system. The load balancer, MySQL LB, which is used to connect to the application, lacks clear documentation. When there are multiple application servers connecting to the MySQL cluster and going through the MySQL load balancer, the documentation is not user-friendly. It's there, but only technical persons with deep knowledge of the MySQL database can implement it. Most of the community users or ISVs who use MySQL don't have many technical persons or DBA experts, so they face some challenges for the high availability of connecting high available databases from high available applications. That documentation should be simplified.

Quotes from Members

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

Pros

"It supports multiple applications and business intelligence tools."
"It is very easy to install IBM Informix, very easy to scale, and support is quite better."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"The initial setup is pretty easy."
"So far, we do not have a lot of issues. It's pretty problem-free."
"Replication is a valuable feature and easy to use."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"The stability is incredible. I have customers with uptimes of several years."
"The fact that it is free is what appeals to me the most."
"My main reason for using MySQL for this small customer database company and for some kinds of scientific projects was that I had to do the installation myself. I didn't have a database administration team behind me. Therefore, I was looking for something very easy to handle. MySQL is easy to install, connect, and do all such things."
"The solution is a small application and is very easy to deploy."
"MySQL is easy and convenient for me. I don't need to rely on anyone. I can write the code and extract the information. It is fast if you know how to use it. The solution is not expensive, and most of the developers know how to use it. It is easy to create tables. The solution is stable and has good performance. The connection with AWS gives regular updates, which is manual otherwise and a nightmare."
"​The most valuable feature of MySQL is the informative error outputs of command line interface.​"
"The initial setup was easy. I work in an agile way, which means coding and deploying quickly."
"It has a remote access feature to manage the database from a remote location. This enables in-work collaboration."
"I am totally satisfied with MySQL."
 

Cons

"This product could be made easier to use for beginners."
"The technical support services need substantial improvement."
"I really would love to have a QT plugin."
"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."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"The solution really doesn't add new features very often."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"This solution is in need of more current tools."
"The solution could have better integration and security features."
"It should have some code analytical functions. It can also have a monitoring tool."
"I would like to see more integrations of the solution with other platforms and improve the support on different data types."
"We have encountered some performance issues, and the solution takes time for performing complex queries."
"We want to continue using MySQL but it merged with Oracle and the scalage changed."
"MySQL lacks a feature akin to Oracle's Real Application Clusters, which ensures continuous database availability within the same data center or nearby data centers."
"The solution could improve by having better performance and security."
"It requires a training platform."
 

Pricing and Cost Advice

"I am not aware of the licensing costs or terms."
"The product has reasonable pricing. We purchase its yearly license."
"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."
"For me, it's always too expensive."
"The price of the solution is good because we have a good partner."
"MySQL is a cheap solution."
"MySQL is a free and open-source solution."
"The pricing falls within the moderate range."
"I use the open-source free community version."
"I rate the solution's pricing as four out of ten, where one is cheap, and ten is expensive. For our basic needs, it's quite affordable. However, the cost increases when we need to scale up or require high availability. Our developer team of about 600 people uses MySQL without much issue. The pricing becomes more of a concern on the business side, as we have more end users and need constant database availability and scaling. In those cases, the solution gets a bit more expensive, even though it provides good value for the business."
"MySQL is released under an open-source license, so you have nothing to pay to use it."
"There is a licensing cost because we are going for a proprietary product. There are some other versions for which there is no licensing cost."
