$LIST string format and %DynamicArray and %DynamicObject classes
IRIS, and previously Cache, contain several different ways to create a sequence containing a mixture of data values. A data sequence that has been available for many years is the $LIST string. Another more recent data sequence is the %DynamicArray class, which along with the %DynamicObject class, is part of the IRIS support for JSON string representation. These two sequences involve very different tradeoffs.
Now that 1.0 has shipped and is featuring in various sessions at Virtual Summit 2020 it seems like a good time to offer some guidance on how to report problems.
Presenter: Anton Umnikov Task: Identify your slowest SQL queries and tune them for better performance Approach: Use InterSystems’ query profiling and analysis tools. Discuss how system configuration can affect performance
This session will show you how you identify the weakest link in your application SQL and introduce you to the fine art of tuning those queries. To do this we will take a look at InterSystems query profiling and analysis tools, as well as how system configuration can impact SQL performance.
Problem: Obscurity on how our SQL engine works

Purpose
We are all gripped by this unprecedented Covid-19 pandemic. While supporting our customers in battlefields by any means, we also observed various fighting fronts against Covid-19 by leveraging today's AI powers.
In this article, we'll talk about an application that I use every day when monitoring applications and integration solutions on the InterSystems IRIS platform and finding errors when they occur.
One useful feature of our REST framework is the ability for a dispatch class to identify request prefixes and forward them to another dispatch class. This approach of modularizing your URL map will improve code readability, enable you to easily maintain separate versions of an interface, and provide a means to protect API calls that only certain users will be allowed to access.
Previously, I shared with you all a handy operational analytics dashboard you can build to visualize key message processing metrics, such as number of inbound/outbound messages, average processing times, etc.
When calling out to web services there are several settings of the Business Operation that play together in controlling what will happen when a response is not returned in the desired time.
By default InterSystems IRIS expose your endpoints using http, but can be necessary run https from your dev env and/or get public internet access to your app. You can buy or get a certificate and config a gateway, spending many hours or use a great public service called ngrok. Follow the steps:
1 - Run your app, I will use FHIR template as sample, see:
N.P.M. is a Project & Task Management app that uses InterSystems IRIS and Bootstrap 4.
No Project Mess is created to help developers and small business companies to reduce complexity in their daily problems, with a simple and intuitive projects and tasks management software.
It offers different views for your tasks, from a spreadsheet, kanban, calendar, or even Gantt!
So, one day you're working away at WidgetsDirect, the leading supplier of widget and widget accessories, when your boss asks you to develop the new customer facing portal to allow the client base to access the next generation of Widgets..... and he wants you to use Angular 1.x to read into the department's Caché server.
There's only one problem: You've never used Angular, and don't know how to make it talk to Caché.
This guide is going to walk through the process of setting up a full Angular stack which communicates with a Caché backend using JSON over REST.
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.
In the WRC, we often see customers who have encountered a problem viewing their SOAP Catalog pages in a browser. This article will explain why the error is being encountered, as well as suggest a fix. This explanation is focused on the symptoms seen in InterSystems IRIS, but similar behavior can be seen in more recent versions of Caché.
The demo is based on the raw class descriptions. The data classes used are Address, Person, Employee, Company For a more attractive demo, a JSONtoString method by ID was added.
It seems to me that for some reason this didn't make its way to the official documentation and seems to be rather unknown though implemented already in IRIS 2020.1
Thanks to @Dan Pasco I got a hint on the classes involved. I used the recommended sequence of how to use it. it is all directly taken from Class Reference and I just collected it to create a first overview.
The Eclipse environment persists perspective data to enable layout customization and other features. Sometimes when this data becomes out of date, Eclipse fails to clear references to it. For example, upgrading a plug-in can leave behind data about an earlier version of that plug-in. This mechanism applies to all Eclipse plug-ins and is not unique to the Atelier plug-in.
In light of this: You may find that after upgrading from Atelier 1.1 to 1.2, your Atelier perspective looks something like:
Error management on InterSystems languages has been evolving along time. Next, we will show the different implementations and why you should use the TRY/THROW/CATCH mechanism.
Recently I noticed a Kaggle dataset for the prediction of whether a Covid-19 patient will be admitted to ICU. It is a spreadsheet of 1925 encounter records of 231 columns of vital signs and observations, with the last column of "ICU" being 1 for Yes or 0 for No. The task is to predict whether a patient will be admitted to ICU based on known data.
The fhir-react project defines a unique component which renders the interface based on FHIR resource type. There's no need for any configuration because the library uses the standard of defined by the resource type.
So, I decided to apply the same idea, but for charts. The basic idea is depicted below:
It design it's really friendly - there's just one component! As FHIR resource types are standards, the framework resolves internally what rendering class must be used.
To display your FHIR resource just write this component:
As I said in the previous article, I started to learn about FHIR for the contest, and I'd like to share an update in my application: detection of inconsistencies in FHIR data.
Nowadays, there is a lot of applications that are using Open Authorization framework (OAuth) to access resources from all kinds of services in a secure, reliable and efficient manner. InterSystems IRIS is already compatible with OAuth 2.0 framework, in fact, there is a great article in the community regarding OAuth 2.0 and InterSystems IRIS in the following link here.
NLP stands for Natural Language Processing which is a field of Artificial Intelligence with a lot of complexity and
techniques to in short words "understand what are you talking about".
And FHIR is...???
FHIR stands for Fast Healthcare Interoperability Resources and is a standard to data structures for healthcare. There are
some good articles here explainig better how FHIR interact with Intersystems IRIS.
