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.

Robust multidimensional database has enabled smooth API integrations and modern data workflows
I think InterSystems IRIS is a continuation of the Caché legacy. Since I have been working with it since 2005 with Caché, I think it is a really amazing tool. It is a very robust and very scalable database. It is very good to work with, and I am already used to working with it. Where it falls a bit short is in the availability of manpower and professionals who work with InterSystems IRIS or Caché. There are few professionals who work with it. Another thing is the cost and the license cost. I think there could be some kind of package that could serve smaller companies and small and medium-sized companies. That would reach a larger slice of the market, because the cost to work with Caché, InterSystems IRIS, and so on is high. I would make this remark about putting together a package and a new product that could serve small and medium-sized companies. The area where InterSystems IRIS falls a bit short is in the cost and the licensing cost. The licensing cost is the main issue I have already mentioned.

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

Pros

"We don't have any problems with the Informix Database."
"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."
"Overall, this is a great product. It works really well, is very stable, and is very scalable."
"The stability is incredible. I have customers with uptimes of several years."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"It supports multiple applications and business intelligence tools."
"OLTP processing capacity and the availability of information with high availability implementation have been significantly improved."
"The scalability is very good."
"InterSystems IRIS as a database is very efficient, with its best features being its speed and high performance, along with an easy understanding of its data searching functionalities."
"In my opinion, the best features that InterSystems IRIS offers are its very optimized database, which I found amazing, and the observability it provides for checking messages and how the data is being transferred, which I find very interesting."
"InterSystems IRIS has had a positive impact on my organization by improving performance and data security."
"The best features InterSystems IRIS offers, in my experience, include being a really powerful engine and a really good database."
"The best features that InterSystems IRIS offers in my opinion are the speed in querying data, and due to our system, which requires a large query with a large volume of data, InterSystems IRIS stands out for its query speed, making my work easier."
"The best features InterSystems IRIS offers are its powerful database and speed, which contribute greatly to my work."
"My final observation is that everyone should use InterSystems IRIS; it is an amazing tool on the market."
 

Cons

"The technical support services need substantial improvement."
"This solution is in need of more current tools."
"Informix is very sturdy, but the problem for us is the marketing action around Informix."
"I would like to see backups from secondary servers."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"The solution should offer replication. It would be helpful if the solution would allow us to access third-party tools."
"The solution really doesn't add new features very often. Other solutions are much more actively pushing out upgrades and improvements."
"The pricing is a bit expensive."
"InterSystems IRIS can be improved by addressing the lack of libraries, mainly mathematical ones, where we would save a lot of time on some formulas that we have to build by hand every time we need them."
"I cannot determine a very positive impact or a beneficial result from InterSystems IRIS, although this observability part is important because we were able to find problems much faster."
"InterSystems IRIS can be improved since its studio is very poor."
"The area where InterSystems IRIS falls a bit short is in the cost and the licensing cost."
"Python support can be enhanced further, as it's really clunky at the moment, considering that the use of Python is pretty much all over the world and nobody knows ObjectScript really thoroughly and deeply."
 

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."
