⏯️  Closing the Scientific Knowledge Gap with AI

For venture capitalists (VCs), evaluating research can be challenging. While researchers typically possess years of training and deep expertise in their field, the VCs tasked with assessing their work often lack domain-specific knowledge. This can lead to incomplete understanding of scientific data and an inability to direct organizational initiatives. To solve this problem, we have designed a solution that empowers VCs with AI-driven due diligence: ResearchExplorer. ResearchExplorer is powered by InterSystems IRIS and GPT-4o to help analyze private biomedical research alongside public sources like PubMed using Retrieval-Augmented Generation (RAG). Users submit natural language queries, and the system returns structured insights, head-to-head research comparisons, and AI-generated summaries. This allows users to bridge expertise gaps while securely protecting proprietary data.

Given:
class Foo.Bar extends Ens.BusinessOperation
{
Parameter SETTINGS = "Whatever:Basic";
}

class Foo.Baz extends Foo.Bar
I want to somehow drop "Whatever" as a setting from Foo.Baz. How can I do this?

I would like to know which are the best practices of using Streams in Interoperability messages.

I have always use %Stream.GlobalCharacter properties to hold a JSON, or a base64 document, when creating messages. This is fine and I can see the content in Visual Trace without doing anything, so I can check what is happening and resolve issues if I have, or reprocess messages if something went wrong, because I have the content.

But I think this is not the best way of using Streams.

While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together. 

1. Working with Dynamic Objects:

Dynamic objects (%DynamicObject and %DynamicArray) allow developers to manipulate JSON-like structures directly in Objectscript. They are especially useful for modern applications that need to parse, transform or generate JSON.

Trying to create a new SQL Storage map on existing cache Global in the following format - ^MYGLO("R",rec)=data where the 'data' is built using $zel. e.g. $zel(data,1)="p1", $zel(data,2)="p2" etc... and the ^MYGLO("R",123)=data.

I'm having 2 issues. First, using the SQL Storage map wizard, I cannot figure out how to convey data in $zel format in the "Delimiter" field. 

Second, since I couldn't figure that out,  I tried to use the "Use Retrieval Code" option and entered the following line for the P1 property:

but get an error when compiling saying I cannot reference another field:

Recently, I replaced my old laptop with a new one and had to migrate all my data. I was looking for a guide but couldn’t find anything that explained in detail how to migrate server connections from InterSystems Studio and Visual Studio Code from one PC to another. Simply reinstalling the tools is not enough, and migrating all the connections manually seemed like a waste of time. In the end, I managed to solve the problem, and this article explains how.

InterSystems Studio

Exporting Server Connections

Migrating Studio connections was the most challenging part.

I try the Large data Save in FHIR server in Binary Resource but it's failed 

Methed: Post , URL: fhirservers/fhir/r4/Binary 

I hit the API but the record not save and same API but base64 data length is 3 lac than it's save without faile.

I pass data on this formet

{

  "resourceType" : "Binary",

  // from Resource: id, meta, implicitRules, and language

  "contentType" : "<code>", // R!  MimeType of the binary content

  "securityContext" : { Reference(Any) }, // Identifies another resource to use as proxy when enforcing access control

  "data" : "<base64Binary>" // The actual content

}

Hi Community,

Sometimes you may need to merge multiple accounts or simply update the email address you use across the different portals in the InterSystems Developer Ecosystem. Since each portal works a little differently, here’s a guide to help you through the process.

Change your email

If you’d like to use a different email (for example, use a work email instead of a personal one, or vice versa), here’s how to update it across the portals:

1. Update your email in InterSystems SSO. To do this:

• log in to login.intersystems.com
• choose Options - Change Email

• follow the prompts on screen to change your email

Or can I change namespaces within one connection object?

Running "docker exec -it iris iris terminal IRIS" automatically logs you in as irisowner in the terminal session, but how do you log in as a different user?

⏯  Can AI Fix Bugs? Evaluating Progress and Challenges

Hello All,

  I have used github (outside of IRIS) for many many years and have no problem with it.  Also used SVN and other source control systems.

  I have a conceptual problem understanding the ISC github links and how they work via VSCode.

https://github.com/intersystems/git-source-control

 Our server is on Linux.

What I've done:

1. On Linux Server - d ##class(SourceControl.Git.API).Configure()

2. Create a local repo (we have a local git), say https://repo/myrepo

3. VSCode installed Object script addons, github Pull requests extension

4. VSCode Connect to namespace on server, all good

This article describes a significant enhancement of how InterSystems IRIS deals with table statistics, a crucial element for IRIS SQL processing, in the 2025.2 release. We'll start with a brief refresher on what table statistics are, how they are used, and why we needed this enhancement. Then, we'll dive into the details of the new infrastructure for collecting and saving table statistics, after which we'll zoom in onto what the change means in practice for your applications. We'll end with a few additional notes on patterns enabled by the new model, and look forward to the follow-on phases of this initial delivery.

Overview

This release delivers expanded Azure support for InterSystems Data Studio, enhanced subscription flexibility, major module updates, and multiple improvements to networking, security, and API responsiveness.

New Features and Enhancements

This article outlines the process of utilizing the renowned Jaeger solution for tracing InterSystems IRIS applications. Jaeger is an open-source product for tracking and identifying issues, especially in distributed and microservices environments. This tracing backend that emerged at Uber in 2015 was inspired by Google's Dapper and Twitter's OpenZipkin. It later joined the Cloud Native Computing Foundation (CNCF) as an incubating project in 2017, achieving graduated status in 2019. This guide will demonstrate how to operate the containerized Jaeger solution integrated with IRIS.

The August Article Bounty on the Global Masters article caught my attention, and one of the proposed topics sounded quite interesting in regard to its future use in my teaching. So, here's what I'd like to tell my students about tables in IRIS and how they correlate with the object model. 

First of all, InterSystems IRIS boasts a unified data model. This means that when you work with data, you are not locked into a single paradigm. The same data can be accessed and manipulated as a traditional SQL table, as a native object, or even as a multidimensional array (a global). It means that when you create an SQL table, IRIS automatically creates a corresponding object class. When you define an object class, IRIS automatically makes it available as an SQL table. The data itself is stored only once in IRIS's efficient multidimensional storage engine. The SQL engine and the object engine are simply different "lenses" to view and work with the same data.

First, let's look at the correlation between the relational model and the object model:

It's not always a 1:1 correlation, as you may have several tables represent one class, for example. But it's a general rule of thumb. 

Over the years, I’ve noticed that certain SQL questions come up repeatedly on the InterSystems Developer Community, especially about using the LIKE predicate in different contexts. Common variations include:

• using special characters in queries
• using variables in queries

and many more derivatives. So, I decided to write an article that focuses on how LIKE works in InterSystems IRIS SQL, especially when used with variables in Embedded SQL, Dynamic SQL, and Class Queries, while touching on pattern escaping and special character searches.

First of all, I'd like to mention that InterSystems IRIS SQL offers most of the capabilities available in other relational DBMS that implement a later version of the SQL standard. But at the same time, it's important to mention that apart from relational access, in IRIS you can also use other models to get the same data, for example, object or document models. 

On this note, let's look at the LIKE predicate and how this tool is used in SQL for pattern matching. 

In the Caché database, when calculating the total count based on the unique identifier of a record, the quantity is over 1.2 million. After removing duplicates based on the unique identifier and then calculating the total count, the quantity is over 400,000. When grouping by the unique identifier, it can be observed that the count for this identifier is not one. However, when performing a conditional query based on the identifier, only one record can be retrieved. Why is this the case?

Dynamic Entities (objects and arrays) in IRIS are incredibly useful in situations where you are having to transform JSON data into an Object Model for storage to the database, such as in REST API endpoints hosted within IRIS. This is because these dynamic objects and arrays can easily serve as a point of conversion from one data structure to the other.

Dynamic Objects

Dynamic Objects are very similar to the standard ObjectScript object model you get when you create a new instance of a class object, but with some key differences:

• Dynamic objects have no real type, other than being a

Is there a way to Remove specific all Addresses from a Provider.Individual.Address before reinserting the Addresses from an HL7 message in Provider Directory?

Most fields we can call %clearFields() however since Addresses come from multiple locations we need to isolate and treat Addresses from this HL7 source as a snapshot.

Thanks

Hi all,

I’m running into an issue with a %ZEN.Component.tablePane in a Zen page.

We have:

• A fully styled table with all columns defined
• A backend query (SearchMessages) that accepts multiple filter parameters
• A set of input fields at the top of the page for filtering (text, date, and checkboxes)

We’re trying to run the query from a button click using a client-side method (runSearch()) that collects the filter values, sets them as parameters, and calls executeQuery().

The problem is that the table does not update at all. Old rows remain, or sometimes nothing appears.

Hello
I want to get the property of a class, sorted by order in storage.

I know we can use
 

Set definition = ##class(%Dictionary.ClassDefinition).%OpenId(className)
        Set listProperty = definition.Properties
        For ii = 1:1:listProperty.Count(){
                    write listProperty.GetAt(ii).Name

But using GetAt sorts the results alphabetically.

Example :

Class Test.classExtends (%SerialObject, %XML.Adaptor, %JSON.Adaptor)
{

    Property tiers As%String;Property journal As%String;
}

listProperty.GetAt(1).Name = "journal" and listProperty.GetAt(2).Name = "tiers"

The operations manager in our company was using structured logging in IRIS to tail information to an on-prem monitoring tool and started to get concerned with the ever-growing size of the output file.He just leaned across the aisle here and informed me that the output file has no mechanism for rolling this file over at a certain point for archival or disposal.Sure enough, I can't find any documentation to refute this.
