We performed a comparison between IBM Db2 Database and IBM Informix based on real PeerSpot user reviews.
Find out in this report how the two Relational Databases Tools solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The solution's initial setup is straightforward."
"IBM Db2 Database has good performance."
"The most valuable feature of the IBM Db2 Database is security."
"The most valuable aspect of this solution is its stability. We have never had any problems and have never had to contact technical support."
"I like that its true active-active. For example, if there are two instances within a cluster, we can take one of them down and there's no failover or switch over. There's no primary and secondary, it's true active-active. We can take one side down and we can upgrade that with new maintenance or a new version, obviously testing coexistence beforehand, without impacting the business."
"The most valuable feature of this solution is the integration with other IBM products."
"The setup process has become much easier recently."
"The solution has many beneficial features, such as security, support, and stability."
"So far, we do not have a lot of issues. It's pretty problem-free."
"Replication is a valuable feature and easy to use."
"This solution has made financial reporting possible by allowing financial people the opportunity to set Informix to "Auto Pilot" so that they can attend other duties."
"For IoT business cases, having Informix Enterprise Edition work on edge computers, like Raspberry Pi and using Informix replication, makes complex situations simple to build and maintain."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"The most valuable feature is concurrency and locking because my customers usually use databases in OLTP mode. So, for a large number of competitive users. Other features that are well valued are quick large-scale data types. It is better than Oracle."
"The stability is incredible. I have customers with uptimes of several years."
"IBM Informix benefits users with high availability and good integration capabilities."
"The capabilities of this solution could improve."
"Also, the website could be more intuitive. I didn't find it easy to find documentation on the website."
"IBM's products tend to be quite costly, especially given the availability of free, open-source alternatives."
"The queries can be difficult for beginners because there are so many. I would like to see more use cases for flow analysis that enable us to correlate the flow with events. Adding this feature in a QI format would be good for beginners."
"I would say that the tool has to be made more cloud-friendly and should have agreements with AWS, Microsoft, or Google to run things on hyperscalers."
"The application development requires a Java developer and not every company has these resources."
"The pricing could be improved, it's expensive."
"The problem with this environment is that any software that you install is very costly because there are no free tools for this environment."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"I experienced poor input/output (IO) performance."
"The solution lacks some functionality."
"This solution is in need of more current tools."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"The solution really doesn't add new features very often."
"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."
