The Power of Indexing in Database Tables

When working with databases, most developers understand the concept of an index and why it's used: to speed up data retrieval. But the real impact of indexing often becomes clear only when you compare scenarios with and without it.

Do you Know what Happens Without an Index?
Imagine a table with three columns: Name, Age, and MobileNumber.

Welcome, dear members of the Community!

In this article, we will present an example of a project implementing a FHIR-based solution. This project will be based on the national project (Spanish national project), known as ÚNICAS.

What is ÚNICAS?

In his own words:

A project whose objective is to create an ecosystem of partnerships to improve healthcare for pediatric patients with complex rare diseases (RMDs). This project is being implemented through the network within the National Health System (NHS) to improve the diagnosis and care of patients with rare diseases.

What's new with InterSystems Language Server 2.7

First, let me wish the developer community a Happy New Year! We hope to bring you many good things this year, and today I'd like to introduce the latest version of the Intersystems Language Server extension to VS Code. Most Language Server improvements are experienced via the ObjectScript extension UI, so you many not be aware of the many improvements in areas like Intellisense and hover overs that were released throughout 2024.

At hackathons that InterSystems participated and I supported, many students were asking how all their teammates could use the same IRIS database that they spun up in a container. I suggested using ngrok to expose their localhost IRIS and realized we don't have documentation on that. Hence, I thought this would be great to let more people knwo about this powerful technique for enhancing collaboration during development and testing.

Hi Community,

While writing an article yesterday, I realized I was so busy with people who came to the Developer Community table at the Tech Exchange that I forgot to take photos for you. Luckily, I realized the error of my ways and corrected my behavior accordingly 😉

So, let's look at what happened on Tuesday at the InterSystems Ready 2025! It began with a speech of Scott Gnau about the approach and architecture of InterSystems Data Platform and how it is different from all other DBMSs:

Hi:

I see a lot of cool REST apps and i'm trying to host something in the TIE using REST/Axios with VITE.

At the moment i will probably host the application in web applications in Intersytems.

For authorisation and getting the logged in user and password to any app, is there a standard people are doing?

I.e. for axios you might have this from the app

Hi Community,

Are you already InterSystems certified, or thinking about taking that next step?

InterSystems certification is a great way to showcase your skills and open new doors—but we'll let our certification holders speak for themselves:

Introduction

Businesses often use in-memory databases or key-value stores (caching layers) when applications require extremely high performance. However, in-memory databases incur a high total cost of ownership and have hard scalability limits, incurring reliability problems and restart delays when memory limits are exceeded. In-memory key-value stores share these limitations and introduce architectural complexity and network latency as well.

This article explains why InterSystems IRIS™ data platform is a superior alternative to in-memory databases and key-value stores for highperformance SQL and NoSQL applications.

Taking Performance and Efficiency to the Next Level

InterSystems IRIS is the only persistent database that can match or beat the performance of in-memory databases and caching layers for concurrent data ingestion and analytics processing. It can process incoming transactions, persist the data to disk, and index it for analytics in under one microsecond on commercially available hardware without introducing network latency.

The superior ingest performance of InterSystems IRIS results in part from its multi-dimensional data engine, which allows efficient and compact storage in a rich data structure. Using an efficient, multi-dimensional data model with sparse storage techniques instead of two-dimensional tables, random data access and updates are accomplished with very high performance, fewer resources and less disk capacity. It also provides in-memory, in-process APIs in addition to traditional TCP/IP access APIs to optimize ingest performance.

Hello, Does the NodeJs package work when running a node js file on windows (nodejs for windows)? I've added the package by running npm install <package location folder>

I have the following index.js file, but when running from node (windows) I get the following error. Does the NodeJs package build the output files when the package is added or does it just assume linux as the underlying os?

Error: Cannot find module './bin/winx64/irisnative.node'

#InterSystems Demo Games entry

⏯️ The Ultimate 3D Industrial Simulation powered by a Game Engine with InterSystems IRIS

In this demo, InterSystems IRIS Interoperability comes alive in an amazing, game-like user experience based on our Ultimate Control Tower demo. We visualize machines in a virtual 3D factory building, interacting with InterSystems IRIS in real time—displaying current statuses and sensor data, simulating machine outages and predictive maintenance scenarios, and triggering workflow tasks and actions in InterSystems IRIS. By using a mobile app on a tablet—and even a VR headset for a fully immersive experience—we unleash the power of InterSystems IRIS.

If you're migrating from Oracle to InterSystems IRIS—like many of my customers—you may run into Oracle-specific SQL patterns that need translation.

Take this example:

SELECT (TO_DATE('2023-05-12','YYYY-MM-DD') - LEVEL + 1) AS gap_date
FROM dual
CONNECT BY LEVEL <= (TO_DATE('2023-05-12','YYYY-MM-DD') - TO_DATE('2023-05-02','YYYY-MM-DD') + 1);

In Oracle:

Digital health solution providers face increasing pressure to integrate complex health data systems while ensuring scalability, security, and compliance with standards like HL7 FHIR. Fast Healthcare Interoperability Resources (FHIR) has revolutionized health data exchange by offering a standardized framework that allows diverse health IT systems to communicate effortlessly. But simply adhering to FHIR standards isn’t enough to overcome the intricacies of health data integration. Solution partners must leverage advanced architectural components like FHIR brokers, façades, and repositories to build scalable and efficient solutions. InterSystems offers all the essential features you need to implement FHIR for your health data, whether on-premises, in a public cloud, or as a cloud-based service managed by InterSystems.
