Using SQL Gateway with Python, Vector Search, and Interoperability in InterSystems Iris

Part 1 - SQL Gateway

Hello

In this article we will look at the use of SQL Gateway in Iris. SQL Gateway allows Iris to have access to tables from other (external) database via ODBC or JDBC. We can access Tables or Views from various databases, such as Oracle, PostgreSQL, SQL Server, MySQL and others.

Modern data architectures utilize real-time data capture, transformation, movement, and loading solutions to build data lakes, analytical warehouses, and big data repositories. It enables the analysis of data from various sources without impacting the operations that use them. To achieve this, establishing a continuous, scalable, elastic, and robust data flow is essential. The most prevalent method for that is through the CDC (Change Data Capture) technique. CDC monitors for small data set production, automatically captures this data, and delivers it to one or more recipients, including analytical data repositories. The major benefit is the elimination of the D+1 delay in analysis, as data is detected at the source as soon as it is produced, and later is replicated to the destination.

This article will demonstrate the two most common data sources for CDC scenarios, both as a source and a destination. For the data source (origin), we will explore the CDC in SQL databases and CSV files. For the data destination, we will use a columnar database (a typical high-performance analytical database scenario) and a Kafka topic (a standard approach for streaming data to the cloud and/or to multiple real-time data consumers).

Overview

This article will provide a sample for the following interoperability scenario:

#InterSystems Demo Games entry

⏯️ Health Evolve: Transforming Unstructured Data

Did you know that 80% of healthcare data is stuck in unstructured formats such as fax? If you take a walk down to Mass General in Boston, you'll literally see a state-of-the-art MRI machine next to a fax machine. Healthcare keeps building incredible new technology but can't let go of legacy technology. We call this the "legacy modernization paradox". This short film follows a care manager at Blue Plan who spends her days doing chart reviews, reading faxes line-by-line, struggling to provide her members the care they need. Everything changes when Blue Plan pilots InterSystems Health Evolve, a solution that transforms her faxes into machine-readable FHIR data ready for AI and analysis. To access our fully working Text-to-FHIR prototype, visit HealthEvolve.de.

Hello,

I am currently trying to edit server side code for TrakCare using Visual Studio Code with intersystems-community.vscode-objectscript version 2.12.11-beta.1.

I can correctly check out the .mac file but when I try to either File > Save or use command 'ObjectScript: Import and Compile Current File' I get a very generic error .

I cannot find any details anywhere in the Output section.

I have reinstalled all extensions several times.

Hi,

It's me again😁, recently I am working on generating some fake patient data for testing purpose with the help of Chat-GPT by using Python. And, at the same time I would like to share my learning curve.😑

1st of all for building a custom REST api service is easy by extending the %CSP.REST

Hi,

Just thought I'd share quite a handy hook that has helped me out when developing on Health Connect Cloud with VS Code and GitBash. When developing on Health Connect Cloud, if changes are made directly on the server such as routing rules or component deployments, they aren't automatically included in source control, therefore you must export from the server into your local files and push to your remote repo. I'm sure there are easier methods to deal with that which I'm in the process of testing, but as a quick solution I thought it would be handy have a pre-commit hook which triggers a reminder in GitBash - see below.

For example, you start debugging the AAA function, which calls the BBB function, then goes to the CCC^ABC function in a different routine and ends up while executing XXX^XYZ. No other routines or functions are visited in this example. What I would like is to get the record of AAA -> BBB -> CCC^ABC -> XXX^XYZ. No marking each function with recording code should be involved: too time consuming, too many functions in real code.

UPD: Iris has built in %SYS.Trace for this purpose but this class is apparently absent in Cache 2017. Did not find any substitutes yet.

Hi, I'm trying to use the iris python package to create a connection to and Iris Health instance (Docker Container), but getting and error. I can login to the instance using the UI with the same uname/password but unable to create the python connection. Any suggestions?

conn = iris.connect("testserver",52222,"%SYS","username","password")

After executing this I get an exception trap
An error occurred: Invalid Message Count: expected: 1 got: 825110831

Dear Community members,

We are currently performing technical work, and during this time, you may experience issues with the Developer Community portal, Developer Community AI, and search functionality:

🔹 Ask DC AI is temporarily unavailable
🔹 Search may take longer than usual or may not return results
🔹 You may experience problems with logging into the Developer Community and Open Exchange

We’re working to restore full functionality as quickly as possible. Thank you for your patience and understanding.

HL7 Pass-through interface

For historic reasons we've got a mix of ADT feeds coming out of our PAS (TrakCare) to a wide range of downstream systems. In particular, there are some that are direct from TrakCare to the downstream systems, and many more that pass through Ensemble as our integration engine.

This is complicating management of the integrations, and so we'd like everything to go through the integration engine. In other words move from the flow in the top of the diagram to the flow in the bottom of the diagram:

Hi everyone,

I'm working with JavaScript in InterSystems IRIS, specifically in CSP pages. One issue I'm running into during development is that the browser keeps loading the cached version of my JavaScript files, even after I’ve made changes or recompiled the code.

I would have to clear my cache files or browser history for it to reload and work.

We have classes in a Production environment that are causing us some issues - example attached.

When we export them from the production environment the XML contains a snippet like the following:

<UDLText name="T">
<Content><![CDATA[
//Property any As list Of %XML.String(XMLNAME = "any", XMLPROJECTION = "ANY") [ SqlFieldName = _any ];

]]></Content>
</UDLText>

When imported and compiled into an Ensemble instance this class works as expected.

Hello everyone,

I'm looking for a practical project guide to help me gain hands-on experience with InterSystems Ensemble HL7. Ideally, this guide would walk through building a small project — something that covers key concepts like message routing, transformations, and interoperability.

What's new with InterSystems Language Server 2.7

First, let me wish the developer community a Happy New Year! We hope to bring you many good things this year, and today I'd like to introduce the latest version of the Intersystems Language Server extension to VS Code. Most Language Server improvements are experienced via the ObjectScript extension UI, so you many not be aware of the many improvements in areas like Intellisense and hover overs that were released throughout 2024.
