In InterSystems IRIS, when you compile a persistent class, you automatically get a SQL table. Sometimes, there are situations that require having a slightly (or not so slightly) different names/options in SQL compared to Object model. Here are some of the settings that you can change to make it happen.

Class-level settings 

They define the "Face" of your class when it appears as a table in the SQL catalog.

SqlTableName allows you to change the name of SQL table that holds objects from your class. This is especially useful, when your class name uses reserved SQL words in a name, e.g. Group.

⏯️ HL7 Validation Error Profiler: Rapid Insights into Batch HL7 Data Quality Issues

This demo highlights how HL7 validation logs can be transformed into scalable, actionable data quality insights using a lightweight application built on top of Health Connect.

  • Batch ingestion and parsing of HL7 validation error logs into structured data
  • Aggregation of errors by segment, field, and type to reveal systemic issues
  • Interactive dashboard (Streamlit) for filtering, exploration, and root cause analysis
  • Rapid identification of top error patterns across entire data feeds
  • Natural language chatbot for intent-driven data investigation and querying
  • PDF report generation for sharing clear, evidence-based feedback during data source onboarding 

Special thanks to @Henry Wojnicki for his contributions to designing and refining the application workflow.

Despite the fact that LOCK (docs) is a foundational part of InterSystems IRIS, responsible for concurrency, there is not a lot of discussion on the Developer Community about it. Which is understandable, considering it's stable and fairly low-level command. In this article, I will show a simple example of how to use locks with interoperability.

Question Touggourt · 5 hr ago

Hi Guys,

I've the below code to build JSON and send it via httpRequest called from business Operation.

But I'm getting this error, which I'm guessing that the formulated JSON doesn't have the correct format, so I was looking to convert the JSONStream to JSON string and try to validate it so see where the JSON is broken, problem is that I'm expecting that there will thousands of records in this JSON so it will hard to go through it, so is there a way to track for error or why this JSON is failing to send    

Thanks

This article introduces SHAP explainability methods as an approach to understand the reasons behind predictions in machine learning black-box models. It also includes a simple Jupyter notebook that you can use and modify to gain hands-on experience with these concepts:

Okay… first things first - sorry it took me so long to write this up. There was just too much happening, too many conversations, too many photos, too much travel and honestly… too much excitement to sit down and write right away.

READY 2026 started the way it always does, with that unique mix of anticipation and energy in the room. Look at these excited faces!

When managing critical healthcare data through an integration engine you want to know the moment a queue starts backing up or a service drops. 

Unfortunately, this usually leads to an email inbox stuffed full of notifications that can sometimes seem impossible to maintain.

Well, I’ve not solved that problem. 

But I have created something that could help...

⏯️ AI-Assisted Rare and Complex Disease Detection

This demo shows how InterSystems Health Gateway can be used to pull in outside patient records from networks like Carequality, CommonWell, and eHealth Exchange, creating a more complete longitudinal view in a clinical viewer. That full record is then analyzed by AI to surface potential rare disease considerations with clear reasoning, helping clinicians see patterns they might otherwise miss.

Question John Murray · May 4

As an experiment in agentic coding in ObjectScript I'm using VS Code to try and create an implementation of an SFTP server.

SFTP is built on top of SSH, so the first phase involves implementing an SSH server. While working on the KEX part of that the agent (using GPT-5.3-Codex) reported:

  1. IRIS has what we already need for signing and hashing: RSASHASign, RSASHAVerify, RSAGetLastError, SHAHash, SHA1Hash, SHA3Hash.
  2. It does not list a Diffie-Hellman key exchange or modular exponentiation API in %SYSTEM.Encryption.

It then offered these options:

  1. Keep using IRIS APIs for cert/key/sign/hash.

Starting out with ObjectScript, it is really exciting, but it can also feel a little unusual if you're used to other languages. Many beginners trip over the same hurdles, so here are a few "gotchas" you'll want to watch out for. (Also few friendly tips to avoid them)


NAMING THINGS RANDOMLY

We have all been guilty of naming something Test1 or MyClass just to move on quickly. But once your project grows, these names become a nightmare. 

➡ Pick clear, consistent names from the start. Think of it as leaving breadcrumbs for your future self and your teammates.

I joined InterSystems less than a year ago. Diving into ObjectScript and IRIS was exciting, but also full of small surprises that tripped me up at the beginning. In this article I collect the most common mistakes I, and many new colleagues, make, explain why they happen, and show concrete examples and practical fixes. My goal is to help other new developers save time and avoid the same bumps in the road.

1. Getting lost among system classes and where to start

The issue: ObjectScript/IRIS ships with many system classes and packages (%Library, %SYS, %Persistent, %SQL, etc.).

Welcome to the next chapter of my CI/CD series, where we discuss possible approaches toward software development with InterSystems technologies and GitLab.

Today I want to share a few approaches that will decrease your compilation time (especially if you're doing incremental/diff compilation rather than a full build).

Compiler flags and qualifiers

Code load and compilation are affected by a variety of flags and qualifiers. If you write deployment scripts for InterSystems platforms, I highly recommend reading them at least once through.

Below is an update to the IRIS release calendar for 2026 and an early look at the planned changes for 2027. The key takeaway for 2026 is that maintenance release numbering will differ slightly from prior years.

2026: IRIS 2026.1 maintenance release numbering

  • July 2026: first maintenance release for IRIS 2026.1 (planned version: 2026.1.4)
  • October 2026: next maintenance release (planned version: 2026.1.5)
  • February 2027: following maintenance release (planned version: 2026.1.6)

This numbering change prepares us for the expanded maintenance cadence planned for 2027.

Question Colin Brough · May 1

We have a large, existing production taking a feed from a single up-stream system and sending to a wide-variety of downstream systems. One of the downstream systems has been decommissioned, and we have deleted the classes that implemented the routing/transformations from the namespace, and deleted the components from the production (Wardview and WV Out in the diagram below). We now want to delete the messages associated with those components without deleting the messages associated with any other components.
