What is Unstructured Data?
Unstructured data refers to information lacking a predefined data model or organization. In contrast to structured data found in databases with clear structures (e.g., tables and fields), unstructured data lacks a fixed schema. This type of data includes text, images, videos, audio files, social media posts, emails, and more.

File Passthrough Feeder

IRIS Interoperability Productions formerly known as Ensemble are fun to work with. Yes, I really think my work is fun. I have seen File Passthrough Services and File Passthrough Operations come in handy. At one point we placed test messages in files, then we utilized a File Passthrough Service with Inbound File Adapter to send the contents of the file as a Stream to a File Passthrough Operation with Outbound TCP Adapter.

tl;dr I have discovered that using $THIS in a very specific way will make persistent objects go stale.

I found that it only happens when using $get on an array that contains the OID reference of $THIS. I assume that this is an unwanted feature and have raised a WRC. The problem can be recreated following the steps below, I have also posted the workaround that I am currently testing and looks to be working fine.

1. Create a persistent class...

Diabetes can be discovered from some parameters well known to the medical community. In this way, in order to help the medical community and computerized systems, especially AI, the National Institute of Diabetes and Digestive and Kidney Diseases published a very useful dataset for training ML algorithms in the detection/prediction of diabetes. This publication can be found on the largest and best known data repository for ML, Kaggle at https://www.kaggle.com/datasets/mathchi/diabetes-data-set.

Introduction

A password manager is an important security tool that allows users to store and manage their passwords without the need to remember or write them down in insecure places. In this article, we will explore the development of a simple password manager using the Flask framework and the InterSystems IRIS database.

Key Features

Our password manager application will provide the following key features:

Presenter: Michael Broesdorf
Task: Use the Internet of Things in a business application
Approach: Demonstrate incorporating device-generated messages into a business process, and using that information to trigger physical events

(Session Sequence: Dependent on EOPEN) IoT may be the most hyped idea of the year, but how do you actually make use of it in your business applications? This session gives a detailed demonstration of incorporating device generated messages into an business process, to interact with your business applications and triggering physical events as a part of a business process.

Introduction to Django part 3

Continuing to observe the possibilities of Django, and usage with IRIS. The first we have looked how to define models and connect to tables already existing in IRIS, than we extended embedded Django Administration portal, with an ability to see what data we have in that models, with filters, editing and even pagination.

Time to go to real action, now we a going to create some REST API, on Django, based on the same data, we used before from the package posts-and-tags.

To do so, we will use Django REST Framework

Django REST Framework

Django REST framework is a powerful and flexible toolkit for building Web APIs.

Some reasons you might want to use REST framework:

  • The Web browsable API is a huge usability win for your developers.
  • Authentication policies including packages for OAuth1a and OAuth2.
  • Serialization that supports both ORM and non-ORM data sources.
  • Customizable all the way down - just use regular function-based views if you don't need the more powerful features.
  • Extensive documentation, and great community support.
  • Used and trusted by internationally recognised companies including Mozilla, Red Hat, Heroku, and Eventbrite.

ODBC / JDBC data truncation

Hi, I hope this post helps.

The bottom line: MAXLEN is relevant mostly for odbc/jdbc connections and you need to specify an appropriate value within your tables (classes), otherwise the data might be truncated when you query it, or even fail when you try to insert data.

Long story:

Task: Build a development stack that enables state-of-the-art rapid development with a stable but adaptive back end.
Approach: Use InterSystems’ new document data model to achieve modern full-stack development

The MEAN stack is a very popular stack for building applications quickly that can change at a rapid pace. We will explore the benefits of such a stack and how you can tackle the requirements for modern and fast paced front-end development with support of a stable, but yet adaptive back-end using our new document data model.

Secure IRIS Digital Services

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.

NewBie's Corner Session 18 Caché or Cache

NewBie's Corner Session 18 Caché or Cache

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Caché and Cache

Caché and Cache are not the same. Caché is a product offered by InterSystems. Whereas Cache refers to memory storage.
In computing, a cache /ˈkæʃ/ KASH, is a hardware or software component that stores data so future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation, or the duplicate of data stored elsewhere.

Abstract

The European Space Agency (ESA) has chosen InterSystems Caché as the database technology for the AGIS astrometric solution that will be used to analyze the celestial data captured by the Gaia satellite.

The Gaia mission is to create an accurate phase-map of about a billion celestial objects. During the mission, the AGIS solution will iteratively refine the accuracy of Gaia's spatial observations, ultimately achieving accuracies that are on the order of 20 microarcseconds.

Multidimensional properties can be found on certain classes.

These operate as a collection of values much like a Python dictionary.

Examples of properties that might be encountered:

Class Property Description
%Net.HttpRequest Params Name value pair of form parameters
%Net.HttpResponse Headers

HTTP Headers returned with web content returned:

Hi Developers!

Many of you are looking for samples on how to work with InterSystems IRIS Analytics, formerly known as DeepSee.

There is a Samples BI module with Patients and Holefoods examples which is available on Github with source code. The installation steps are clear but take time.

Recently we added the option to run IRIS Community Edition containers with ObjectScript Package Manager (ZPM) on board. This simplifies the installation to the "run-one-command" step for the modules submitted to ZPM Community Registry. And thus we can benefit the Samples BI installation with ZPM.

And here is how you can run it on your laptop. Let's go!

WebTerminal is broken on IRIS 2024.2

I'm posting this for the benefit of WebTerminal users who have upgraded to the recently-released IRIS 2024.2 -- (Build 247U) Tue Jul 16 2024 09:52:30 EDT -- or are considering doing so.

That version of 2024.2 contains a change (DP-432503) which requires that the user under which the Web Gateway initially connects to IRIS (usually CSPSystem) must have READ permission on the database hosting the dispatch class of the REST web application.

Create JSON Objects and Arrays by SQL

The related package avoids adding %JSONAdaptor to each class but uses instead
SQL functions JSON_OBJECT() to create my JSON objects. With this approach, you can
add JSON to any class - even deployed ones - without any need for change or recompiling.

The trigger was the Export of M:N relationships as JSON objects or arrays.

Introduction

This article aims to explore how the FHIR-PEX system operates and was developed, leveraging the capabilities of InterSystems IRIS.

Streamlining the identification and processing of medical examinations in clinical diagnostic centers, our system aims to enhance the efficiency and accuracy of healthcare workflows. By integrating FHIR standards with InterSystems IRIS database Java-PEX, the system help healthcare professionals with validation and routing capabilities, ultimately contributing to improved decision-making and patient care.
