Not so long ago, I came across the idea of using Python Class Definition Syntax to create IRIS classes on the InterSystems Ideas Portal. It caught my attention since integrating as many syntaxes as possible gives visibility to InterSystems’s products for programmers with experience in many languages.
When creating custom Business Hosts, it's often necessary to add properties to the class for additional settings that will be used in the initialization or operation of the host. The property name itself isn't always very descriptive, so it's an advantage to have a custom caption display with the field.
The traditional use of an IRIS production is for an inbound adapter to receive input from an external source, send that input to an IRIS service, then have that service send that input through the production.
Yet another example of applying LangChain to give some inspiration for new community Grand Prix contest.
I was initially looking to build a chain to achieve dynamic search of html of documentation site, but in the end it was simpler to borg the static PDFs instead.
As a former JAVA developer it has always been a challenge to decide which database was the most suitable for the project we were going to develop, one of the main criteria I used was their performance, as well as their HA configuration capabilities ( high availability). Well, now is the time to put IRIS to the test with respect to some of the most commonly used databases, so I've decided to create a small Java project based on SpringBoot that connects via JDBC with a MySQL database, another of PostgreSQL and finally with IRIS.
We conclude this series of SMART On FHIR articles with Auth0 and InterSystems IRIS FHIR Repository by reviewing our application developed in Angular 16.
Let's remember what the architecture defined for our solution is like:
Our front-end application corresponds to the second column and as you can see it will be in charge of two things:
It seems like yesterday when we did a small project in Java to test the performance of IRIS, PostgreSQL and MySQL (you can review the article we wrote back in June at the end of this article). If you remember, IRIS was superior to PostgreSQL and clearly superior to MySQL in insertions, with no big difference in queries.
You can set the maximum size of the IRISTemp database at IRIS startup by setting a configuration parameter called MaxIRISTempSizeAtStart.
After setting, the system will truncate IRISTemp to the set value (MB) at the next IRIS startup. If the current size is less than the specified MaxIRISTempSizeAtStart, no truncation will occur. Also, if 0 is specified, truncation will not be performed, so the size will start without changing. (Default) Settings are made from the menu below.
When using InterSystems IRIS as an interoperability engine, we all know and love how easy it is to use the Message Viewer to review message traces and see exactly what's going on in your production. When a system is handling millions of messages per day, you may not know exactly where to begin your investigation though.
Over my years supporting IRIS productions, I often find myself investigating things like...
Methods written in ObjectScript can use pass-by-reference arguments to return information to the caller. Python doesn’t support pass-by-reference arguments, so Embedded Python in IRIS doesn’t support them either. That's it, that's the end of the post, hope you liked it. 😉 But wait, what about the Classic Rock & Roll?
In the sample below, an image file is encoded into a Base64 string in a class property, saved, decoded again with Base64, and restored to another file.
【Usage class】
Class User.test Extends %Persistent
{
Property pics As %GlobalBinaryStream;
}
Are you preparing to use VS code for the first time? Just make sure you have enough privileges.
Have you defined your Iris server in your VS Code settings, and still get the following error?
VS Code accesses Iris/HealthConnect using the web application /api/atelier. If you do not have permission (i.e. you are using an LDAP user to connect and the web application is not configured to support LDAP), this is the reason why you couldn't connect.
In a customer project I was asked how you can keep track of database changes: Who changed what at which date and time. Goal was to track insert, update and delete for both SQL and object access.
This is the table that I created to keep the Change Log:
In my recent post Quality of Open Exchange packages, I tried to raise attention on Pull Requests and Issues (on GitHub). I could count the replies on 1 hand. Special Thanks to the French Community!
I see the role of a Pull Request as a proposal to fix a problem in the submitted package.
The IKO allows for sidecars. The idea behind them is to have direct access to a specific instance of IRIS. If we have mirrored data nodes, the web gateway will (correctly) only give us access to the primary node. But perhaps we need access to a specific instance. The sidecar is the solution.
Building on the example from the previous article, we introduce the sidecar by using a mirrored data node and of course arbiter.
In recent versions of IRIS, a powerful new data loading command has been introduced to SQL: LOAD DATA. This feature has been highly optimized to import data into IRIS extremely fast, allowing hundreds of gigabytes of data to be inserted in seconds instead of hours or days.
This is a very exciting improvement. However, a big problem in the data loading experience still exists. Namely, the time and hassle it takes to:
In the modern digital age, securing applications, particularly those handling sensitive health data, is paramount. The confidentiality, integrity, and availability of such data are crucial, necessitating robust security measures. Two-factor authentication (2FA) stands out as a critical enhancement in safeguarding access, adding an extra layer of security beyond just passwords. Recognizing the significance of this feature, InterSystems provides built-in support for 2FA in its database solutions. This tutorial aims to guide you through the process of configuring two-factor authentication in your InterSystems environment, ensuring that your data remains secure and accessible only to authorized users.
What is Unstructured Data? Unstructured data refers to information lacking a predefined data model or organization. In contrast to structured data found in databases with clear structures (e.g., tables and fields), unstructured data lacks a fixed schema. This type of data includes text, images, videos, audio files, social media posts, emails, and more.
This article is intended to describe how the clinFHIR application can be used to help developers both understand FHIR and to develop applications that utilize FHIR artifacts. It’s not intended to be an introduction to FHIR, but rather describe how clinFHIR can help on the learning / development journey.
I created this application considering how to convert images such as prescription forms into FHIR messages
It recognizes the text in the image through OCR technology and extracts it, which is then transformed into fhir messages through AI (LLA language model).
Finally, sending the message to the fhir server of IntereSystems can verify whether the message meets the fhir requirements. If approved, it can be viewed on the select page.
Hibernate is the most popular framework to do ORM (Object Relational Mapping) projects. With Hibernate a software can use the main DBMS in the market, including the capability to change the database vendor any time, without source code impact. This is possible because the Hibernate supports dialects. Each database product has a different dialect that can be assigned into a configuration file. So, if a software is using Oracle and is looking to evolve to InterSystems IRIS, just change the configuration file with connection and dialect information.
Following 2 local Webinars we had focused on VS Code ["Intro" and "Beyond Basics"; in Hebrew], I prepared for the participants some related links of relevant resources which we sent as a follow-up. Sharing them here as well for the benefit of the Community. You are all of course welcome to add more useful resources.
