#InterSystems IRIS

Hey Developers,

The InterSystems Analytics Contest is over. Thank you all for participating in our exciting coding marathon!

And now it's time to announce the winners! 

A storm of applause goes to these developers and their applications:

Hi Community,

Learn how to use validation tools in InterSystems IRIS to assess and validate the behavior of a production:

⏯ Validating Your InterSystems Productions

There are couple of options to do this.

1. You can extend your class &JSON.Adaptor, it will do it for you with inbuilt logicaldtodisplay methods

2. Create another request class and do your transformations

3. Before calling the json convert to stream methods, transform the object's field with a ZDT.

---------------------------------------------------------------------------------------------------------------------------------------

I have an extremely simple example where there is a class with 3 properties

Class NV.Operations.FileOutbound.Data.

Hi guys.

That time I'll show you a way to use a machine learning model implemented using IntegradeML as source for an IRIS analytics cube dimension.

Creating the ML model:

Execute this SQL in order to create a new ML model using IntegratedML SQL extension:

CREATE MODEL AppointmentsPredection 
PREDICTING (Show) 
FROM (SELECT 
  Canal, 
  CreacionDate, 
  CreacionHora, 
  Edad, 
  Especialidad, 
  Latencia, 
  ReservaDate, 
  ReservaHora, 
  Sexo, 
  Tipo 
FROM dc_myapp_model.MedicalAppointments

Now, you can train you model:

TRAIN MODEL AppointmentsPredection FROM dc_myapp_model.MedicalAppointmentsTrain

The question has come up several times and I saw mixed answers and no quick example

My personal preference is using CPIPE device as you get back exactly the output you will get at the command line interface of your OS .
The tricky thing is to stop reading in time.
The example just displays what you normally see in your console.
it becomes useful if you look for things that you can't get from any $system.whatever()

e.g.
- your servers IP address or addresses depending on your configuration.

Hi developers!

We had a set of technology bonuses for the InterSystems Analytics contest.

And here is how projects collected it:

This table is subject to change upon project improvements or if we missed something.

How difficult is it to create a report using InterSystems Reports?

The InterSystems IRIS has two major paths to a digital service: API/Web Service into Interoperability module and multimodel Database/Analytics. Each of them has your security configuration.

To do API security you apply an OAuth or JWT plug-in to the API endpoint. So in the Admin Portal, API producer and consumers get the keys to authenticate the API and consume it. The Admin Portal allows you configure RBAC policies too.

To do WS security the best strategy is to use SAML. In the inbound/outbound SOAP message, include X.

Did you know that you can get IRIS Analytics features as an REST API?

In this article I'll show some endpoints of IRIS Analytics Business Intelligence REST API, used in my project iris-analytics-notebook to create a pivot table component in Angular.

How to vote? 

Please meet the new voting engine and algorithm for the Experts and Community nomination:

Hi everyone,

It's the bottom of the 9th inning, but I have a few more plays to make in our technical World Series 

The InterSystems IRIS has a very nice container class to allows you have your Dashboards as classes source code. It is %DeepSee.UserLibrary.Container.

With this class is possible group all your dashboard and pivot table definitions.

This is useful to automatically create your dashboards when you build your docker project and other automation scenarios.

Hey Developers,

Are you ready to participate in the annual December competition?

Join the Advent of Code 2020 with InterSystems and participate in our ObjectScript contest to win some $$$ prizes!

Today, is important analyze the content into portals and websites to get informed, analyze the concorrents, analyze trends, the richness and scope of content of websites. To do this, you can alocate people to read thousand of pages and spend much money or use a crawler to extract website content and execute NLP on it. You will get all necessary insights to analyze and make precise decisions in a few minutes.

Gartner defines web crawler as: "A piece of software (also called a spider) designed to follow hyperlinks to their completion and to return to previously visited Internet addresses".

Hello guys.

Can anyone help me about Global ^Errors? Only in 1 specific namespace is it growing fastly. It grows from 2 to 3 Gb per hour when all services are active. Which commands exactly do this? In another similar namespaces, there is not that Global in the class list.

Thanks.

Hi guys!

I'd like to present you my new project: iris-analytics-notebook, a notebook approach to use IRIS analytics capabilities.

Project description

In past few years, notebooks tools like Jupyter are gaining popularity due its natural way to express ideias.

An almost unipresent tool for data scientists, notebook can also help to improve the impact of analytics tools for all sort of users.

This project is my attemp to implement a simple notebook system, combining IRIS Analytics capabilities, with a custom notebook system - largelly inspired by Jupyter notebooks.

I compiled some data about past InterSystems DC constest.

About this article:

In InterSystems IRIS, the default form of access to the management portal is HTTP, which means that if the client is in the office and the server is in the cloud, many clients probably desire to encrypt their traffic in some way.

Thus, we would like to show you some ways to encrypt your traffic to and from the IRIS management portal (or various REST services) running on AWS.

This article uses the IRIS built-in apache server for access. It should not be used for benchmarking purposes or as a method of access from production environments applications.

Web Crawling is a technique used to extract root and related content (HTML, Videos, Images, etc.) from websites to your local disk. This is allows you apply NLP to analyze the content and get important insights. This article detail how to do web crawling and NLP.

To do web crawling you can choose a tool in Java or Python. In my case I'm using Crawler4J. (https://github.com/yasserg/crawler4j).

Crawler4j is an open source web crawler for Java which provides a simple interface for crawling the Web. Using it, you can setup a multi-threaded web crawler in few minutes.

Hi fellows,

I'm glad in annouce that now I'm certified:

Hi community, I used website-analyzer - an app that uses InterSystems NLP and Crawler4J to extract all website content and do NLP on it. I limited to 200 pages and discovered this:

Top 10 Concepts - business and content topics in the InterSystems site:

Other frequency concepts, see the focus in the iris speed, scale and data value:

Top 10 Concept Dominance - business relations in the InterSystems site.

If I have table of 60 fields is there a way to add values to columns dynamically ?

Fields are like this Field1, Field2, Field3...Field60 and I am reading data from flat files. I tried below code but it didn’t work

For i=2:1:$LENGTH(line) {

set SourceTable.Field_i = $PIECE(line, "|", i)
 

Hi,

Do you have a guide or tutorial with recommendations to configure IRIS to a production environment? The better strategies, recommended disk, memory and processing settings, etc?

Hey Developers!

We're pleased to invite you all to the next competition of creating open-source solutions using InterSystems IRIS! Please join:

🏆 InterSystems Analytics Contest 🏆

Duration: December 7 - 27, 2020

Hi folks!

Do we have an embedded REST API in IRIS which accepts arbitrary SQL and returns data in JSON?

Or if anyone did something like this?

The idea is to have something like MDX2JSON but SQL2JSON.

Thanks!

Hi fellows,

I'm glad to share with you my new certification:

Languages like Java and C++ allows to develop a multi-threaded program with two or more parts that can run concurrently and each part can handle a different task at the same time making optimal use of the available resources specially when your computer has multiple CPUs. Is it possible In ObjectScript? If yes, Where I can get a good sample or application?

Hi Developers,

You asked for it – we did it!

We are introducing a new voting engine and algorithm to InterSytems Contests which you can try with the current contest – starting next Monday!

Hello,

We are working with a vendor who only accepts JSON as payload. We are currently still on Cache/HealthShare, not IRIS. Since we have to send Continuity of Care Documents, this raises issues with Long Strings (some CCDs can be quite large and in addition to that, they have to be b64-encoded which increases their size even more).

My question is: if we were to go on IRIS and use %JSON.Adapter, storing the encoded Stream in an object's Stream property, would calling %JSONExport() on this object produce the desired JSON? Or would we have to call %JSONExportToStream()?
