InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.
There are always those who say that their child looks more like their mother or their father. How about using math and Artificial Intelligence to be sure? The facial-matching application can answer you.

I need to reproduce a table (in fact a view, but let's start with a simple table 😊) in IRIS as the currently used in Oracle.
I need to expose/project one column to JDBC as CLOB, in my class I have the corresponding property defined as:
Property GlobStream As %Stream.GlobalCharacter;
In JDBC this column is projected as LONGVARCHAR, this is compliant with the documentation but I need to project it as CLOB.
In addition, I'm no expert in JDBC but wit seems that LONGVARCHAR has a Maximum Length 32,700 characters in JDBC, not quite enough for an arbitrary stream.
Picture a dark room. The only light comes from a wall of displays and a blinking prompt that politely informs you:
“LINK TO M-U5K-3T: HIGH LATENCY – DIRECT CONTROL DISABLED.”
Perfect.
You are supposed to be a Rover Commander in the Musketeer Corps. Somewhere absurdly far away, you have an autonomous unit parked on a hostile exoplanet. It wants you dead, but it’s also covered in minerals that could fund a small civilization.
The ore on M-U5K-3T is everywhere. Unfortunately, everything else on the surface is actively trying to kill you.
So, we don't pilot. We script.
Hello everyone,
I’m looking to implement Continuous Training (CT) as part of an MLOps strategy for some data science projects in IRIS. I want to automate the full cycle:
- Monitoring model performance & accuracy degradation.
- Retraining models automatically.
- Validating and updating production models.
I’ve looked into IntegratedML, but it seems more focused on the SQL interface for training (AutoML). Even with the new Custom Models (beta), which allows for more flexibility with Python, it doesn't seem to provide the "Continuous" orchestration out of the box.
I’d like to know:
The facial recognition has become the most popular method for validating people's identities, thus enabling access to systems, confirmation of personal and documentary data, and approval of actions and documents.
The challenges are related to performance when the database is very large, accuracy, and especially the privacy of biometric facial data. For these challenges, nothing is better than using InterSystems Vector Search, as it allows:
The standard %Net.HttpRequest library in InterSystems IRIS is powerful and comprehensive, but it can be verbose for simple operations. Writing an HTTP request often requires several lines of code to instantiate the class, configure the server, the port, HTTPS, add headers, and finally send the request.
When testing in the terminal, this configuration quickly becomes too heavy, and usually ends up with the creation of temporary methods...
FastHTTP was designed to address this need. This utility class provides a fluent and concise interface to perform HTTP calls in a single line, while automatically handling the underlying complexity (SSL/TLS, URL parsing, JSON encoding, headers, etc.).

One objective of vectorization is to render unstructured text more machine-usable. Vector embeddings accomplish this by encoding the semantics of text as high-dimensional numeric vectors, which can be employed by advanced search algorithms (normally an approximate nearest neighbor algorithm like Hierarchical Navigable Small World). This not only improves our ability to interact with unstructured text programmatically but makes it searchable by context and by meaning beyond what is captured literally by keyword.
In this article I will walk through a simple vector search implementation that Kwabena Ayim-Aboagye and I fleshed out using embedded python in InterSystems IRIS for Health. I'll also dive a bit into how to use embedded python and dynamic SQL generally, and how to take advantage of vector search features offered natively through IRIS.

Transformer based LLMs appear to be a pretty good "universal logical–symbolic abstractor". They started to bridge up the previous abyss among human languages and machine languages, which in essence are all logic symbols that could be mapped into the same vector space.
Wondering for 3 years we might be able to just use English (etc human natural languages) to do IRIS implementations as well, one day.
This is an excellent candidate for a developer community post (like Dev.to, Medium, or the InterSystems Community). It bridges the gap between high-level architecture and hands-on implementation.
Here is the summarized article format.
As applications scale, handling heavy computational tasks synchronously becomes a bottleneck. Whether it's processing large data sets, sending high-volume emails, or managing API integrations, a decoupled architecture is essential.
Hi developers!
I'm testing vibecoding with ObjectScript and my silicon friend created a code-block that got me thinking "what's wrong"?
Here is the piece of code:
for i=0:1:(json.%Size()-1) {
set p = json.%Get(i)
if (p="value1")!(p="value2") {
quit1
}
AI wanted to quit from a method with a return value. Good intention, but bad use of the command.
And ObjectScript compiler compiles this code with no error(?) (syntax linter in VSCode says it's a syntax, kudos @Brett Saviano ).
But in action, it produces <COMMAND>, of course.
Hi Developers!
Currently I have 2000+ lines in a class, and I think it's a lot already? What are the best practices?
if 10K lines OK? How do you cope with it? Please share?
We use local containers a lot for evaluation and development with Health Connect and other IRIS based applications.
When evaluating Podman Desktop on Windows as replacement for Docker Desktop, we are experiencing an issue with the durable %SYS:
When I build docker containers my build log usually looks like this:
In the previous article, we examined how we can use the %CSP.Request and %CSP.Response classes to test a REST API without having the API fully set up and accessible across a network with an authentication mechanism. In this article, we will build on that foundation to perform some simple unit testing of one of our REST API methods.
Hello DC community,
InterSystems Certification is currently developing a certification exam for ObjectScript developers, and if you match the exam candidate description below, we would like you to beta test the exam! The exam will be available for beta testing starting February 18th, 2026.
Beta testing will be completed May 4, 2026.
We are attempting to "Repoint" old class data to new class data to save disk space and data redundancy across multiple tables. This works to a point. In essence the two classes are sharing the same data / Index / stream globals. But if an ID in the Old_Class is opened, a property is modified, and saved the property that is in the New_Class (but not in the Old_Class) is NULLed / blanked.
Simplified explanation of data and what’s occurring.
Intersystems IRIS Productions provide a powerful framework for connecting disparate systems across various protocols and message formats in a reliable, observable, and scalable manner. intersystems_pyprod, short for InterSystems Python Productions, is a Python library that enables developers to build these interoperability components entirely in Python. Designed for flexibility, it supports a hybrid approach: you can seamlessly mix new Python-based components with existing ObjectScript-based ones, leveraging your established IRIS infrastructure. Once defined, these Python components are
Welcome to the finale of our journey in building MAIS.
Now, the stage is set. Our agents are ready, defined, and eager to work. However, they remain frozen in time. They require a mechanism to drive the conversation, execute their requested tools, and pass the baton to one another.
In this article, I aim to demonstrate a couple of methods for easily adding validation to REST APIs on InterSystems IRIS Data Platform. I believe a specification-first approach is an excellent idea for API development. IRIS already has features for generating an implementation stub from a specification and publishing that specification for external developers (use it with iris-web-swagger-ui for the best results). The remaining important thing not yet implemented in the platform is the request validator. Let's fix it!
Recent versions of IRIS come with Lite Terminal available from VSCode. It's a websocket server, with JSON messaging. Here's how to connect to it from Python:
Hi developers!
In a method I need to return a result as a dynamic object aka JSON Object. And here is my logic:
Classmethod Planets() as%DynamicObject {
set val1="Jupiter"
set val2="Mars"// this doesn't work! cannot compile
return {"value1":val1, "value2":val2}
}So I need to do the following:
Classmethod Planets() as%DynamicObject {
set val1="Jupiter"
set val2="Mars"
set result={}
set result.value1=val1
set result.value2=val2
return result
}Hello everyone. I'm currently working on how to implement a solution that makes it possible to include within the response of a BusinessOperation the "RetryCount" for each message.
For Example, we have this message that was retried twice:.png)
This is an HL7.message going through a specific business operation, we did not create a custom one: we used the default implementation EnsLib.HL7.Operation.TCPOperation. This operation should automatically handle retries (infinetely waiting on a response). I found out each Business Operation has this property :.png)

The 2025.1.3 maintenance releases of InterSystems IRIS® data platform, InterSystems IRIS® for HealthTM, and HealthShare® Health Connect are now Generally Available (GA). These releases include the fixes for a number of recently issued alerts and advisories, including the following:
I have always struggled with Iterating through a JSON response to pull out certain fields into a Data Class Structure to use to populate fields in a DTL. So I defined the whole structure for the following JSON, with the base structure extending Ens.Response, %XML.Adaptor, and %JSON.Adaptor.
There seems to be a generous use of ClassMethods in ObjectScript code generally. I hope my own experiences aren't representative, but I bet they are. Forgive me for giving away the ending of this article, but in short: don't use them. Unless you can make a pretty convincing case that you have to, just never use them.1
What is a ClassMethod? In an ObjectScript class, you can define methods in two different ways: in a Method, you must instantiate an instance of the class to call the method, and in a ClassMethod, you can call the method without instantiating the class. Of course, in a ClassMethod, you don't have access to any properties of the object (because there's no object), but you can access globals (they are global, after all) and Parameters (which are class constants).
