Over the past year or so, my team (Application Services at InterSystems - tasked with building and maintaining many of our internal applications, and providing tools and best practices for other departmental applications) has embarked on a journey toward building Angular/REST-based user interfaces to existing applications originally built using CSP and/or Zen. This has presented an interesting challenge that may be familiar to many of you - building out new REST APIs to existing data models and business logic.
InterSystems IRIS
InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

In this article, I will show how you can easily containerize .Net/Java Gateways.
For our example, we will develop an Integration with Apache Kafka.
And to interoperate with Java/.Net code we will use PEX .
Architecture
Our solution will run completely in docker and look like this:
Open Exchange App Dockerfile and Friends or How to Run and Collaborate to ObjectScript Projects on InterSystems IRIS

Hi Developers!
Many of you publish your InterSystems ObjectScript libraries on Open Exchange and Github.
But what do you do to ease the usage and collaboration to your project for developers?
In this article, I want to introduce the way how to introduce an easy way to launch and contribute to any ObjectScript project just by copying a standard set of files to your repository.
Let's go!

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.

This is the third post of a series explaining how to create an end-to-end Machine Learning system.
Training a Machine Learning Model
When you work with machine learning is common to hear this work: training. Do you what training mean in a ML Pipeline?
Training could mean all the development process of a machine learning model OR the specific point in all development process
that uses training data and results in a machine learning model.

Hi Developers!
As you know the application errors live in ^ERRORS global. They appear there if you call:
d e.Log() in a Catch section of Try-Catch.
With @Robert Cemper's approach, you can now use SQL to examine it.
Inspired by Robert's module I introduced a simple IRIS Analytics module which shows these errors in a dashboard:

The InterSystems IRIS has an integration engine with these core elements:
1. Adapters: are inbound (data/message input/request) and outbound (data/message output/response) integration logic specialized in the type of data or message protocol (file, http, etc.). They are the interface to allows connect with source or target data repositories or systems.
2. DTL: is a component to mapping and transform data between two components in the flow orchestration.

This is a coding example working on IRIS 2020.1 and on Caché 2018.1.3
It will not be kept in sync with new versions
It is also NOT serviced by InterSystems Support !
In most cases, a global used by default storage has just 1 subscript level that represents the IDKEY.
For an index-globals we may see 2 or more subscript levels.
Arrays, or parent-child relationships or persistent classes extending a base data class
are examples where we see more levels. Though all these globals are quite uniform.

Globals in Caché / Ensemble / IRIS are normally invisible over SQL access
This example shows how to overcome this limit.

During my search for a snapshot of a persistent object,
I met a feature that I would like tho share as it could be useful in some special situations.
My trigger was to have a before- and an after-image during unit testing.

Standard error logs in IRIS / Caché / Ensemble are written global ^ERRORS.
As this piece dates back some decades back to previous millennium its structure
is far from the typical SQL storage structures.

Setting up Management Portal Help Pages for Full WebServers
On each page of the System Management Portal, there is a “Help” button. This takes users to an article in documentation that describes the page functionality and use.
Caché provides local documentation for all of these articles.
InterSystems IRIS does not provide local documentation. Instead, the Help button will redirect users to the articles in the online documentation at docs.intersystems.com.

Hi Developers!
Recently we launched InterSystems Package Manager - ZPM. And one of the intentions of the ZPM is to let you package your solution and submit into the ZPM registry to make its deployment as simple as "install your-package" command.
To do that you need to introduce module.xml file into your repository which describes what is your InterSystems IRIS package consists of.
This article describes different parts of module.xml and will help you to craft your own.
I will start from samples-objectscript package, which installs into IRIS the Sample ObjectScript application and could be installed with:
zpm: USER>install samples-objectscript
It is probably the simplest package ever and here is the module.xml which describes the package:
<?xml version="1.0" encoding="UTF-8"?>
<Export generator="Cache" version="25">
<Document name="samples-objectscript.ZPM">
<Module>
<Name>samples-objectscript</Name>
<Version>1.0.0</Version>
<Packaging>module</Packaging>
<SourcesRoot>src</SourcesRoot>
<Resource Name="ObjectScript.PKG"/>
</Module>
</Document>
</Export>

The offer of ZPM is growing daily and the short names and
acronyms of the offer are sometimes hard to understand and
also hard to type with my lazy fingers.

This an example of a customized SystemFunction extension (ZZISJSON) in Caché & IRIS
This time it is to be included in %ZLANGF00.mac
A JSON string is mostly imported from a file or over REST.
You rely on a clean and compatible structure. This is the check.

This is a follow-up to my previous article WebSocket Client JS with IRIS Native API as Docker Micro Server
Installation is now much simpler as all pieces are now assembled in a single Docker image.
That makes life easier. But of course, the principle of the Micro Service is not so obvious anymore.
An All-in-1 bundled package. Therefore compact.

Background
Device #2 named SPOOL dates back to the predecessors of Caché and IRIS
It was the first "%Stream" like option to buffer output before printing.
It is also the first and still today the most simple way of output redirection.
This is my introduction to a series of posts explaining how to create an end-to-end Machine Learning system.
Starting with one problem
Our IRIS Development Community has several posts without tags or wrong tagged. As the posts keep growing the organization
of each tag and the experience of any community member browsing the subjects tends to decrease.
First solutions in mind
We can think some usual solutions for this scenario, like:

Wrap JSON to multi lines / Test ISJSON
This is a coding example working on Caché 2018.1.3 and IRIS 2020.2 It will not be kept in sync with new versions It is also NOT serviced by InterSystems Support !
install and usage
Packed Pretty.xml installs routine ZPretty in any namespace.
calling $$Do^ZPretty(input,[filler],[newline]) returns a wrapped JSON string.
filler is the optional string for the indent, default = " "
newline is optional, default = $C(13,10)
input accepts: JSON_String, JSON_Stream, %DynamicAbstractObject
IRIS and Caché / Ensemble offer the possibility to add Languages Extension as SystemFunctions, SystemVariables, SystemCommands
The related documentation tells you where to add the system-wide extension. Parameter passing is not covered explicitly.
Currently, the process of using machine learning is difficult and requires excessive consumption of data scientist services. AutoML technology was created to assist organizations in reducing this complexity and the dependence on specialized ML personnel.
AutoML allows the user to point to a data set, select the subject of interest (feature) and set the variables that affect the subject (labels). From there, the user informs the model name and then creates his predictive or data classification model based on machine learning.
