I face the challenge to have a bunch of classes on IRIS and CACHÉ in parallel
until all systems are migrated to IRIS.

Applying changes in Caché development environment and moving  to IRIS is no problem

But if I have to apply a fix on IRIS there seems to be no clean way back to Caché.

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 !

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.

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:

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.

A few months ago, I read this interesting article from MIT Technology Review, explaing how COVID-19 pandemic are issuing challenges to IT teams worldwide regarding their machine learning (ML) systems.

Such article inspire me to think about how to deal with performance issues after a ML model was deployed.

Hi everyone,

when I'm using the %JSONExport-function on Caché-Objects containing properties of type %integer, %numeric or %boolean, this properties are all automatically converted to Strings in the JSON-Output.

Is there a way to get around this type-cast?

Example:

Result with %JSONExport:

maxOrderable and maxReserveable are of type %integer, deliverable and assembly of type %boolean. All 4 properties are shown as quoted Strings.

During the development of the Terminal Multi-Line Command Editor I discovered in my IRIS installation
a piece of software that I just can classify as a historic artifact. And it is still fully operational !!!

As it dates back to times before InterSystems was founded in 1978 you may understand my surprise.
I personally stepped into that environment in 1978 and used it then for daily work.

GA releases are now available for the first version (v1.0) of InterSystems System Alerting and Monitoring (InterSystems SAM for short)
  
InterSystems SAM v1.0 provides a modern monitoring solution for InterSystems IRIS based products. It allows high-level views of clusters and single-node drilled down metrics-visualization together with alerts notifications.  This first version provides visualization for more than one hundred InterSystems IRIS kernel metrics, and users can extend the default-supplied Grafana template to their liking.

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.

Hi,

I am brand new to Cache and have been tasked with extracting data from the dB. I see that there are a bunch of tools that can be used to extract via SQL Server statements. DataGrip and DBeaver to name 2. I've gone through some documentation and it doesn't look as if SSMS can connect directly.  Is there a preferred extraction tool that anyone can recommend. Does the Cache dB have anything built in where I can access the data while seeing a visual of the tables/schema?

Thanks for any advice,

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.

I have been looking into using abstract classes and methods. In other languages, if a superclass is defined as abstract, subclasses inheriting from the superclass will not compile until all abstract methods have been implemented in the subclass.
I have created the following classes to try this in Cache:
Class User.Music.AbstractClass [ Abstract ]
