InterSystems IRIS currently limits classes to 999 properties.

But what to do if you need to store more data per object?

This article would answer this question (with the additional cameo of Community Python Gateway and how you can transfer wide datasets into Python).

The answer is very simple actually - InterSystems IRIS currently limits classes to 999 properties, but not to 999 primitives. The property in InterSystems IRIS can be an object with 999 properties and so on - the limit can be easily disregarded.

FHIR has revolutionized the healthcare industry by providing a standardized data model for building healthcare applications and promoting data exchange between different healthcare systems. As the FHIR standard is based on modern API-driven approaches, making it more accessible to mobile and web developers. However, interacting with FHIR APIs can still be challenging especially when it comes to querying data using natural language.

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.

In Caché, it was fairly straightforward:

3DES support

There are several ways of classifying cryptographic algorithms: 1) Secret Key Cryptography (SKC) - Uses a single key for both encryption and decryption. It is also called symmetric encryption. Primarily, it was used for privacy and confidentiality; 2) Public Key Cryptography (PKC) - Uses one key for encryption and another one for decryption. It is also called asymmetric encryption.

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.

How to track your activity on DC

Hey Developers,

If you wish to know how you're doing in the Community and see your stats, you don't need to scroll through all your posts in your profile (though it is also possible). You can use the Online Analytics Dashboard. In it you can see your own detailed statistics for the current week, month, and all time, including:

  • number of views, likes, comments, followers
  • timeline graphics of views, likes, actions with your posts, comments
  • a table containing info about views, comments, and likes for your every post

      In response to a community question asking to view Request and Response message types in Production settings..

      A community helper class was implemented should people need this. ( alwo.EnsHelper.HostRequestResponseInfo )

      Install

      zpm install alwo-enshelper

      The code may serve as an example, to project bespoke configuration into Production settings.

      Hello again everyone.

      In our previous article we saw how to configure our EMPI to receive FHIR messages. To do this we installed the FHIR Adapter that InterSystems made available to us that configured a REST endpoint to which we could send our FHIR message. We would then get the message and transform it to a %String that we would send via TCP to the output of our EMPI configured in our HSPIDATA namespace.

      Alright, it's time to see how we retrieve the message, transform it back to a %DynamicObject and parse it to the class used by the EMPI to store the information.

      In the WRC, we often see customers raise questions regarding a new Web Gateway setup where the Management Portal half-loads, but doesn’t show images. This article will explain why this error occurs, as well as how to fix it. This explanation is focused on the Web Gateway serving InterSystems IRIS instances, but the same explanation should apply to the CSP Gateway serving Caché instances as well.

      Starting in version 2021.1, InterSystems IRIS began shipping with a python runtime in the engine's kernel. However, there was no way to install packages from within the instance. The main draw of python is its enormous package ecosystem. With that in mind, I introduce my side project zpip, a pip wrapper that is callable from the iris terminal.

      Now the Classes/Rutines/DeepSee files will be automatically exported to the working directory after saving or compiling and files will be automatically deleted .

      Installation

      To install isc-dev , you just need to download and import the file isc-dev.xml from last release.
      Some ways to import isc-dev .xml file:

      • Go to Management Portal -> System Explorer -> Classes -> Import and select the XML file.
      • Drag the file over Studio.
      • Terminal command:
      NS>do $system.OBJ.Load("yourpath/isc-dev.xml","ck")

      NS>zpm
zpm: NS>install isc-dev

      How to enable this feature:

      • After importing the class in the target namespace, run the following method to set up the working directory:
      NS>do ##class(dev.code).workdir("/path/to/your/working/directory/src/")
      • Go to Management Portal -> System Administration -> Configuration -> Additional Settings -> Source Control.
      • Select the target namespace and set the dev.FileManExtension class as the main one and save it.
      • Try to create a new class in the studio and save/compile it
      • Enjoy!

      We return to the attack with our EMPI!

      In previous articles we have seen how to configure and customize our EMPI, we have seen how we can include new patients in our system through HL7 messaging, but of course, not everything is HL7 v.2 in this life! How could we configure our EMPI instance to work with FHIR messaging?

      In this article, we will explore the use of parameters, formulas and labels in Logi Report Designer (formerly Logi JReport Designer). What are they for and how to create them?

      Using the basic functionality of InterSystems Reports Designer, parameters, formulas and labels, you can significantly improve the detail and information content of the generated report. In addition, these tools allow you to automate some of the processes, which greatly speeds up and facilitates the creation of reports.

      Let's analyze each tool separately now.

      InterSystems IRIS offers various ways how to profile your code, in most cases it produces enough information to find the places where the most time is spent or where the most global sets. But sometimes it's difficult to understand the execution flow and how it ended at that point.

      To solve this, I've decided to implement a way to build a report in a way, so, it's possible to dive by stack down
