(3 reviews) ## InterSystems IRIS Reviews ### 1. Powerful Out-of-the-Box Components and Effortless Customization **Rating:** 5.0/5.0 stars **Reviewed by:** George G. | Integration Consultant, Small-Business (50 or fewer emp.) **Reviewed Date:** December 18, 2025 **What do you like best about InterSystems IRIS?** It works! There are loads of pre-built components that you can use straight out of the box, the data transformations GUI is very simple to use, and if you need to create custom business components, this can be easily done using code. So you can essentially solve all interoperability problems with IRIS. **What do you dislike about InterSystems IRIS?** Sometimes the documentation for methods can be non-existent. The documentation may just say the method name, with no explanation on what it does. This means that you may have to look at the underlying code to determine what a particular method does. Which can obviously be time consuming. **What problems is InterSystems IRIS solving and how is that benefiting you?** Enabling different healthcare systems to communicate with one another can make a significant difference. If this connectivity helps reduce the time clinicians spend accessing specific sections of your health record, it means they can devote more attention to you, rather than spending valuable time figuring out how to retrieve your data. ### 2. Unified Programming and Complete Documentation Facilitate Use **Rating:** 4.0/5.0 stars **Reviewed by:** Daniel s. | Estagiário, Mid-Market (51-1000 emp.) **Reviewed Date:** January 08, 2026 **What do you like best about InterSystems IRIS?** I find it very useful because of the way it is programmed and the way SQL connections are made, as everything is integrated. The global variables part is also very good, and the documentation is quite complete, making it easy to find what I need. **What do you dislike about InterSystems IRIS?** I'm not a big fan of the screen creation part, as I find the ZEN framework a bit complicated to use. Additionally, I miss native resources aimed at Brazil. Another point is that the community is mostly American or European, which makes it even more difficult for those seeking support or specific content for our country. **What problems is InterSystems IRIS solving and how is that benefiting you?** The quick creation of tables makes everything much easier, and the ability to create components is also a great differentiator. ### 3. InterSystems IRIS: Powerful Evolution with Outstanding Community Support **Rating:** 4.5/5.0 stars **Reviewed by:** Andre L. | Software Quality Analyst, Information Technology and Services, Mid-Market (51-1000 emp.) **Reviewed Date:** November 25, 2025 **What do you like best about InterSystems IRIS?** Like the evolution of Caché, InterSystems IRIS has greatly improved with its added tools and the increased possibility of using other languages ​​with it. The increased use of generative AI, as well as machine learning and analysis, has made it even more effective. A very positive improvement has also been the growth of the developer community, always ready to help and support, as well as the InterSystems employees themselves. "Support" has become much faster this way. **What do you dislike about InterSystems IRIS?** While it's a normal evolution to stop using certain components, I believe that the lack of support for these deprecated items, or a suggestion closer to the current tool, somewhat hinders development for clients who don't update as quickly. **What problems is InterSystems IRIS solving and how is that benefiting you?** I believe that the possibility of using newer development tools, not restricting ourselves to the more classic and older Caché environment, is emerging. ### 4. InterSystems IRIS: Integration and Performance in One Place **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.) **Reviewed Date:** December 23, 2025 **What do you like best about InterSystems IRIS?** What impresses me most about InterSystems IRIS is the way it solves the problem of technological fragmentation. In many projects, you need a relational database, a cache for performance, a search engine, and an integration tool (ESB) all separately. IRIS puts all of this into a single high-performance "box." **What do you dislike about InterSystems IRIS?** The steep learning curve of the proprietary ObjectScript language and the smaller community compared to open source technologies are the main technical friction points I observe. **What problems is InterSystems IRIS solving and how is that benefiting you?** Companies, especially in the healthcare and finance sectors, often deal with dozens of isolated systems that do not communicate with each other. InterSystems IRIS resolves this fragmentation through a robust integration mechanism, with an embedded Enterprise Service Bus, that translates and connects these environments; in healthcare, for example, it natively interprets complex protocols like HL7 and FHIR, allowing laboratories and electronic health records to exchange data in real time. In addition to unifying communication, the platform eliminates delays caused by the common need to separate transactional databases from analytical ones. By acting as a Translytical solution, IRIS can process heavy analytics via SQL or Analytics simultaneously with the ingestion of thousands of transactions per second in the same database, ensuring high performance without bottlenecks. ### 5. Essential Platform with Stellar Support, Steep Learning Curve **Rating:** 4.5/5.0 stars **Reviewed by:** Stav B. | DevOps Engineer, Computer Software, Enterprise (> 1000 emp.) **Reviewed Date:** January 29, 2026 **What do you like best about InterSystems IRIS?** I really appreciate the Worldwide Response Center (WRC) provided by InterSystems IRIS.

It can handle huge amounts of data and transactions without slowing down. I also love that it’s flexible; you can use SQL, NoSQL, object storage, or even work directly with its unique “globals” all in the same system. The built-in tools for connecting different systems (like HL7 and FHIR in healthcare) are a big win, and having analytics built right in means you can get insights from your data without a lot of extra work. As a developer, I appreciate that I can use different programming languages, ObjectScript, Python, or Java or even mix them depending on what the job needs. And above all, it’s dependable, which is essential for systems that can’t afford downtime. It is very simple to use and administratively friendly. The customer support is great often responded within a day. Based on my frequency of use, it is very reliable and developer-friendly. **What do you dislike about InterSystems IRIS?** The main challenge with IRIS is that it takes some time to learn, especially if you’ve never worked with ObjectScript or globals before. Some of the older tools for managing and developing on it feel a bit outdated compared to newer software environments. The licensing can be a bit complicated and may be pricey for smaller projects or startups. The community is helpful but smaller than big open-source platforms, so finding certain answers can take longer.

You can now even do your programming in Python, which opens up a ton of new possibilities. It's been very rare that we've run into something that IRIS didn't have the built-in functionality to get the job done. When you need help, both the community website and the customer service are great. In fact, you can get to talk to actual people at InterSystems very quickly! **What do you dislike about InterSystems IRIS?** IRIS is a bit pricier than most other solutions, and their built-in Analytics tool is a little bit inelegant and clunky to work with. **What problems is InterSystems IRIS solving and how is that benefiting you?** We provide an industry-specific ERP solution. We run almost all of that system on IRIS. The only things we haven't been using InterSystems products for are barcode recognition and displaying reports, and we are working on migrating to InterSystems Reports - which is available at no charge with IRIS - for the latter. This is a very high performance database, and we aren't yet even taking advantage of all of the technologies they offer to improve the performance, such as table sharding. ### 35.

Quicker release on containers. **What problems is InterSystems IRIS solving and how is that benefiting you?** We solve anything and everything about healthcare data interoperability across LABS and Hospitals in the United States.

It kept all the good qualities such as agility, stability and security and added new functions. It became the number one option for me. **What do you dislike about InterSystems IRIS?** It's not a problem, however the fact that it is a new tool and that developers should only gradually start to migrate, eventually situations may appear that still have no resolution, however, as there is a very active community in Caché, this should be easily done contoured. **What problems is InterSystems IRIS solving and how is that benefiting you?** We started to migrate some of the systems I work with to this new tool.
