What I find really useful about IRIS when teaching my subject of Postrelational databases is the fact that it is a multi model database. Which means that I can actually go into architecture and structure and all that only once but then show the usage of different models (like object, document, hierarchy) using the same language and approach. And it is not a huge leap to go from an object oriented programming language (like C#, Java etc) to an object oriented database.

However, along with advantages (which are many) come some drawbacks when we switch from object oriented model to relational. When I say that you can get access to the same data using different models I need to also explain how it is possible to work with lists and arrays from object model in relational table. With arrays it is very simple - by default they are represented as separate tables and that's the end of it. With lists - it's harder because by default it's a string. But one still wants to do something about it without damaging the structure and making this list unreadable in the object model.

So in this article I will showcase a couple of predicates and a function that are useful when working with lists, and not just as fields.

As you have seen in the latest community publications, InterSystems IRIS has included since version 2024.1 the possibility of including vector data types in its database and based on this type of data vector searches have been implemented. Well, these new features reminded me of the article I published a while ago that was based on facial recognition using Embedded Python.

Is it possible to start a terminal attached to a process (JOB)?

For example, I have a 548 process being debugged by VSCODE.

I would like to start a terminal, attached to the process to check process global values ​​by running the command "zw ^||MYGLOBAL"

The data model of your solution based on InterSystems platforms constantly changes over time. But what do you do with the data that was entered before? Back then, the data was valid, but what’s happening to it now after a number of data model changes? The answer to this question can be provided by the IDP DV tool that checks the property data of persistent and serial classes according to the types of these properties. In case any discrepancies are found, the tool generates a detailed error report for the user.

One good thing about COVID-19 is that it taught people that online work and study are possible. I remember a week before the lockdown started, everyone said that working online was impossible, not secure, etc. And what do you know, it all became possible and "secure" in the blink of an eye. As with everything, it depends on whether a person is capable of organizing his or her day and their work or study attitude. Thus, I became a great believer in online education. As an associate professor who teaches databases, I find it beneficial to my schedule and students. One thing that studying online brings is flexibility. Another one is accepting third-party courses to grant credits to my students 😉

Considering that I'm teaching the basics of IRIS, I thought a new course, Getting Started with InterSystems IRIS for Coders, could be a relevant addition to my course. Therefore, I decided to follow the new Learning Path and see how it corresponds to my Syllabus and how many ECTS credits I can give for finishing it.

Hi All,

I'm trying to create a simple wrapper class around a JSON schema validator library, written in Java, and calling this functionality through the Java Gateway of IRIS 2019.1.

My Java wrapper class has a constructor like this:

public JSONValidator(char[] jsonStream, char[] schemaStream) { ... }

Hi All,

I'm trying to connect to an IRIS instance using VSCode, the problem is, there are 2 IRIS instances installed on this server, published by the same hostname using https (port 443) under 2 different subfolders (e.g., iris.demo.com/base & iris.demo.com/test).

When connecting via studio, I was able to connect by using the hostname (e.g., iris.demo.com) and specifying the super server port, while when connecting through VSCode, when specifying the web server port 443, the connection is always defaulted to one of the instance.

IRIS GUI/DTL Rewrite

Hi,

I've heard from two different sources the SMP (or parts of it) and for sure the DTL front end (in studio? via SMP?) have been rewritten to be more modern. But on a latest IRIS Community download everything looks the same to me. Am I missing something or is this Marketting Spin?

Hopefully I won't get banned for this post aswell......

I am building a web application that uses JWT for authentication. I would like to pass the token in cookies instead of the Authorization header.
Is there a way to intercept the request and check the token from the cookies instead of the header? I tried overriding the OnPreDispatch() method and adding it to my dispatch class, but it seems like it never gets executed, as the response returns "Unauthorized" before reaching it.

ObjectScript Json Patch

objectscript-json-patch

alt text

An implementation of JSON-Patch in ObjectScript.

Why you should use JSON-Patch

JSON-Patch (RFC6902) is a standard format that allows you to update a JSON document by sending the changes rather than the whole document.
JSON Patch plays well with the HTTP PATCH verb (method) and REST style programming.

Setting Python

Hi Guys,

I'm a newbie running IRIS in a container (IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2024.3 (Build 217U) Thu Nov 14 2024 17:30:43 EST) and trying to setup Python so I can start working on ML & Autosklearn,my understanding is that IRIS already comes with embedded Python but unable to do something like "import pandas as pd" in VSCode which looks like I need install a more complete version of Python or packages, so what I'm missing?

In this article I'd like to share with you a phenomena that is best you avoid - something you should be aware of when designing your data model (or building your Business Processes) in Caché or in Ensemble (or older HealthShare Health Connect Ensemble-based versions).

Announcing gj :: locate. A simple extension for VS Code that will help you get to the source of your errors.

In VS Code, using either the Serenji extension or the basic InterSystems objectscript extension, this small add-on will open the appropriate class or routine and position you at the exact line where an error occurred.

No more tedious counting of lines to find <UNDEFINED>zCredit+206^Ledger.Invoice.1. Instead, with gj :: locate you can get there with just a couple of clicks.

This 20 second video tells it all:

InterSystems SAM is a great tool to monitor your InterSystems IRIS and InterSystems IRIS For Health clusters on prem or in a cloud environment. This article describes how you can implement a customized alert handler. This is currently an undocumented and most likely an unknown feature of InterSystems SAM. With future releases it will be probably made easier to leverage this useful concept.
