In a project I'm working on we need to store some arbitrary XML in the database. This XML does not have any corresponding class in IRIS, we just need to store it as a string (it's relatively small and can fit in a string). Since there are MANY (millions!) of records in the database I decided to reduce as much as possible the size without compressing. I know that some XML to be stored is indented, some not, it varies.
A beginner’s guide to Exception Handling in RESTful web services. The article gives an example how the various error conditions during processing a service request can be handled.
We expect our client – server communication working in a flawless operational condition, running error free software. But we are prepared to handle exceptions. Are we? So far in the examples of the previous sessions were not. We did not care about exceptions. The result? In any error incident it took ages to figure out what the problem is and more importantly how to fix it.
In this article I'd like to discuss asynchronous REST and approaches to implementing it.
Why do we need asynchronous REST? Simply put - answering the request takes too much time. While most requests usually can be satisfied immediately, some can't. The reasons are varied:
You need to perform time-consuming calculations
Performing action actually takes time (for example container creation)
etc.
The solution to these problems is asynchronous REST. Asynchronous REST works by separating request and real response. Here's an example, let's consider the following simple async REST broker:
Recently DigitalOcean introduced new plans for droplets, but as existing droplets stayed on the old plans I decided to use API to resize them automatically. After reading tutorial, I wrote partial client for DigitalOcean API, which I would like to share today.
This series of articles would cover Python Gateway for InterSystems Data Platforms. Execute Python code and more from InterSystems IRIS. This project brings you the power of Python right into your InterSystems IRIS environment:
Keywords: COVID-19, Medical Imaging, Deep Learning, PACS Viewer, and HealthShare.
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.
The InterSystems IRIS has functions that allows create DIWK digital services. A few products have the ability to transform data into wisdom, according to the following pyramid.
Embedded python gives the option to load and run python code in the InterSystems IRIS server. You can either use library modules from Python pip, like numpy, pandas, etc, or you can write your own python modules in the form of standalone py files.
So once you are happy with the development phase of the IRIS Embedded Python solution there is another very important question of how the solution could be deployed.
One of the options you can consider is using the ZPM Package manager which is described in this article.
I'm participating in the Developing with InterSystems Objects and SQL with Joel Solon. The course is very nice and I will share with you some tips I got during the training. Tips presented in the day 3:
During my recent work on Tutorial - Working with %Query #1 I met a Class Property that is quite different from its same-named relatives. It is there since 'ever' but is rarely used, Related doc doesn't help so much.
InterSystems IRIS offers various ways how to profile your code, in most cases it produces enough information to find the places where the most time is spent or where the most global sets. But sometimes it's difficult to understand the execution flow and how it ended at that point.
To solve this, I've decided to implement a way to build a report in a way, so, it's possible to dive by stack down
Recently @Anastasia Dyubaylopublished a post (this one) showing a new IntegratedML functionality for time series predictions that @Thomas Dyaralready presented to us at the Global Summit 2023 so, let's go to set up a small workshop to test
Welcome to the third and final publication of our articles dedicated to the development of RAG applications based on LLM models. In this final article, we will see, based on our small example project, how we can find the most appropriate context for the question we want to send to our LLM model and for this we will make use of the vector search functionality included in IRIS.
Traditional keyword-based search struggles with nuanced, domain-specific queries. Vector search, however, leverages semantic understanding, enabling AI agents to retrieve and generate responses based on context—not just keywords.
This article provides a step-by-step guide to creating an Agentic AI RAG (Retrieval-Augmented Generation) application.
Implementation Steps:
Create Agent Tools
Add Ingest functionality: Automatically ingests and index documents (e.g., InterSystems IRIS 2025.1 Release Notes).
There's plenty of goodness in the %-packages InterSystems supplies, and it seems that every new version of Caché brings something new. The browser-based class documentation (a.k.a. Documatic) generally provides a good level of information, but on the basis that "a picture is worth a thousand words" I sometimes want a diagram.
For example, when trying to navigate the %Dictionary package for a project that needed to find out about class definitions, here's one of the UML class diagrams I created.
In my previous posting about the new support in QEWD for JSON Web Token (JWT) support, I mentioned that it was a key step in enabling Micro-Service support in QEWD. In this post I'll give some background to how they work and the thinking behind them.
If you haven't heard about Micro-Services and/or want to learn more, there's lots of information available if you do a Google Search. Here's a good starting point:
The class method "test" in the following code snippet sends an HTML email with an embedded image. Edit the literal strings to change the embedded image, to address, from address, subject, and body of the email.
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!
In this article I will demonstrate the functionality of my app iris-energy-isodata . Application is accessing energy data (production, demand and supply) from the major Independent System Operators (ISOs) in the United States to ensure sustainable consumption and production patterns (SDG's 12)
When developing interoperability productions, it might be useful to have settings outside of a Business Host. The primary reason is when you need a setting to affect several different Business Hosts and want to guarantee that the value is the same. While System Default Settings can be used to propagate settings for Business Hosts, they can be changed by overriding the value on a BH level (although the advantage of Business Host settings set via SDS is that they don't need custom code which our current approach requires). Another reason is when you need to affect non-setting parts of the Business Host configuration (PoolSize, Enabled, etc.)
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:
I was struggling with a procedure that was meant to receive a string and use it as a filter, I've found that since I want the procedure to do some data transformation and return a dataset, I needed to use objectScript language.
I've created the procedure using the SQL GUI in the portal, and everything works fine when calling the procedure from the SQL GUI but not through a JDBC connection here is the call "call spPatientOS('2024-04-07T12:35:32Z')"
We're excited to announce the first-ever UI update for CCR Client Tools. The Client Tools UI has been upgraded to match the modern CCR UI, aiming to create a more seamless experience across both applications. The color scheme, fonts, and style elements have all been updated accordingly in the new UI:
What do you do if you want to have the ID field have a meaningful name for your application?
Sometimes it comes to pass that when you're making a new table that you want to have the unique row identifier (a.k.a. IDKEY) to be a field that has a name that is meaningful for your data. Moreover, sometimes you want to set this value directly. Caché fully supports this functionality and it works Suppose you have a class Test.Kyle. The data will be stored like so:
Cross-origin Resource Sharing (CORS) is one of the basic security features built into browsers. CORS controls accessing resources from a HTML page in domains other than the original domain. It is particularly important for AJAX calls. Since RESTful services can be used as data provider to any AJAX call, you have to be able to control cross-origin access. By default services are not allowed to do CORS. You are going to learn how to enable it for Ensemble RESTful services.
I wanted to see some alerts that occur in my Productions in a Mobile Device, I came across Pushover.net recently that although has an upfront cost $5 you can send as many messages as you like after that, there is a 7 day free trial to check it out.
To Integrate this with a production I did the following.
