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.

Real-time analytics have transformed response times and support huge data volumes with compression
I do not have any comment related to the improvement of the solution; for sure, it needs improvement, but for my use cases, it is very sufficient, and I think for the biggest companies, it needs a very powerful infrastructure. The area where improvement is required the most in the product is the UI. The problem with the UI is that it is not complex for understanding, but it needs some training to know what each button does, how it works, and the many variables needed.

"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."

"The best features that InterSystems IRIS offers are its capability to function as both a relational and non-relational database, with performance and speed as specific functionalities that serve as differentiators."
"We use the tool for real-time data transfer for risk management purposes. In a trading system, conversions happen fast. We use the product to handle fast transactions with low latency."
"Performance is probably the number one feature, because when we use it for OLTP, the response for the end-user is pretty fast, with website response times in micro milliseconds instead of waiting a few seconds for a page to load."

Cons

"InterSystems IRIS could be improved, particularly the internal interface of the database."

"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."
"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."
"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."
"The area where InterSystems IRIS falls a bit short is in the cost and the licensing cost."
"The solution is very expensive."
"Technical support is below our expectations currently. It could be improved."
"Personally, this solution wouldn't be my top choice, as it makes things difficult."
