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.

Has successfully supported tenant data separation and enabled strong analytics capabilities
We use VPD, Virtual Private Database, for the multitenancy. We are selling products and using Oracle Multitenant for tenants, for building the product for our customers. We have many customers, actually thousands, and the main objective is to separate data from one customer to another The…

Quotes from Members

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

Pros

"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."
"Flexible Grid provides the ability to automatically create database objects, such as tables, indexes, and stored procedures on all nodes within the grid as a single operation."
"So far, we do not have a lot of issues. It's pretty problem-free."
"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."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"Replication is a valuable feature and easy to use."
"Informix can support huge quantities of data with less memory and less capacity."
"My advice is to take it; you will never regret it."
"The modernization aspect of Oracle Multitenant is significant; it wasn't available previously in database technology, but now it is, enhancing database consolidation."
"It is quite stable. We have not faced any kind of instability in the database."
"With the right configurations, you can maintain an environment without retaining the risk of losing any kind of data."
"The plug/unplug is the great feature, that doesn't even need the Multitenant option."
"The analytics tool, Oracle Analytics Server (OAS), is the main important component of this solution and in the analytics part, the VPD handles all the necessary functions effectively."
"The best thing about Oracle Multitenant is its ability to consolidate multiple databases into one engine."
"The most valuable features are the speed and ease of use."
"The cloning features are outstanding."
 

Cons

"The solution lacks some functionality."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"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."
"I really would love to have a QT plugin."
"This product could be made easier to use for beginners."
"The solution doesn't include functionality like data anonymization."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"Stability and full feature coverage will come with future release."
"From the scope of improvement, I would say that people are adopting new query options. Certain databases like MongoDB adopt new query options so that they can just pull the data."
"Oracle has a lot of work to do with Multitenant because it's a new feature."
"While the product is overall excellent, it is quite expensive."
"Technical support could be faster."
"The main area for improvement is regarding backup and recovery. Today, it’s difficult to set a pluggable database to a former point in time because flashback pluggable database doesn’t exist."
"The only issue is that shared files for the main container affect all container databases if something happens to them."
"Oracle Support is relatively unprepared for this. It has improved, but it still has a lot of room for improvement."
 

Pricing and Cost Advice

"The product has reasonable pricing. We purchase its yearly license."
"I am not aware of the licensing costs or terms."
"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."
"For me, I will go with it if I have the budget. Some features are nicer than before, but at the end of the day, you always have a limited budget. I prefer to upgrade and get a specific hardware when possible. At the end, you will have to make a compromise. You will not get everything you would have liked to have."
"This solution is a little bit pricey."
"The price is worth the quality."
