InterSystems IRIS is a Complete Data Platform InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data. As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.
Terminal scripts can be used to run pre-designed commands on the terminal, like a batch file. You can write anything that can be executed on terminal, like for loop, if else and so on, inside Terminal scripts. In this article, I will show you how to call Terminal scripts, how to use parameters in Terminal scripts and how to avoid session disconnected when running Terminal scripts. If you have any information about how to use Terminal scripts or you have any feedback, please feel free to leave a comment.
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:
I was first introduced to TDD almost 9 year ago, and I immediately fell in love with it. Nowadays it's become very popular but, unfortunately, I see that many companies don't use it. Moreover, many developers don't even know what it is exactly or how to use it, mainly beginners.
In Cache'/Ensemble, by specifying the objectsPackage parameter, dictionaries (and other objects) get projected to tables that can be accessed by SQL queries.
But in IRIS (IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2019.1 (Build 507U) Mon Feb 25 2019 13:47:16 EST), when I created a dictionary with ##class(%iKnow.Matching.DictionaryAPI).CreateDictionary(), it does not get projected to a table.
The class APIs correctly retrieve information about this dictionary.
Am I missing something with IRIS, or is there any issues about this?
IRIS brought us a new WOW feature - SHARDING ! Definitely a great thing! But how can I find out if it suits my actual applications? Is there a practical advantage to go for it with my well cooked transactional application? Or is it just for new still to be designed applications?
I'm facing the error 7802 ("Worker job/s unexpectedly shut down") when trying to work with the Queue Manager. Since today it was working fine, but suddenly today it started failing when arriving to the line:
Till the end of this summer, I have few hours per day that I can spare. I am keen to invest those hours by being part of a good project as a Technical Consultant where I can extend my expertise and connect with fellow colleagues of the community.
The titular question was quite relevant and often discussed some thirty years ago. The thought went: “Sure, there are industries where computers are the norm, but in my industry we got just fine so far, the benefits are questionable, problems innumerable and unsolved. Can we continue as before or should we embrace this new technology?”
Today, everyone asks the same question but about Machine Learning and Artificial Intelligence. The doubts are the same – lack of expertise, lack of known path, perceived irrelevancy to the industry.
Yet, as before, the correct, even the only possible answer is a resounding yes. Read on to find out why.
This is the working example of a light weight export to EXCEL based on data in SAMPLES namespace. Good old CSP is well equipped to produce HTML tables accepted from EXCEL as input. With modern Browsers you don't even need and tags. So the required code around your SQL result set is really slim. And you are free to add any formatting you need either by HTML or in SQL.
I use Documatic a lot to generate class documentation from comments embedded in the code. Is there a good way to create documentation for SQL views as well? Ideally I want to document each column in the view with HTML markup similar to how I document each method of a class with Documatic.
In order to prioritize functional requirements for evolving our SQL developer experience, we have prepared a short survey to better understand how you’re currently using and, in an ideal world, would like most to interact with our SQL platform.
How Tax Service, OpenStreetMap, and InterSystems IRIS could help developers get clean addresses

In my previous article, we just skimmed the surface of objects. Let's continue our reconnaissance. Today's topic is a tough one. It's not quite BIG DATA, but it's still the data not easy to work with: we're talking about fairly large amounts of data. It won't all fit into RAM at once, and some of it won't even fit on the drive (not due to lack of space, but because there's a lot of junk). The name of our subject is FIAS DB: the Federal Information Address System database - the databases of addresses in Russia. The archive is 5.5 GB. And it's a compressed XML file. After extraction, it will be a full 53 GB (set aside 110 GB for extraction). And when you start to parse and convert it, that 110 GB won't be enough. There won't be enough RAM either.
This is a continuation of my story about the development of my project isc-tar started in the first part.
Just having tests is not enough, it does not mean that you will run tests after all changes. Running tests should be automated, and when you cover all your functionality with tests, everything should work well after any change in any place. And Continuous Integration (CI) helps to keep the code and deployment procedure with as fewer bugs as possible and automates the routine procedures, like publishing releases.
I use GitHub to store the source code. And some time ago GitHub started to work on their own CI/CD platform and named it GitHub Actions. It is not widely available, yet. You have to be signed as a beta tester for this feature, as I did. GitHub Actions uses quite a different way how to deal with a build workflow. What is important that Github Actions allows to use docker, and it’s quite easy to customize available actions. And interesting that GitHub Actions is really much bigger than any classic CI like we have in Travis, Circle or Gitlab CI and so on. You can find more in the official documentation.
I'm sure most of you have already familiar with the possibility of using GZIP in InterSystems products. But, the problem is that GZIP working only with one file or stream, and it does not support folders. When you work in Unix systems, there is a possibility how to solve it, using tar compress tool which goes with every Linux system from out of the box. But what to do if you have work on Windows as well, which does not have it.
I am pleased to offer you my new project isc-tar, which will help you do not care about operating system, and deal with tar files anywhere.
I am just recently announced my project isc-tar. But sometimes it is not less interesting what’s behind the scene: how it was built, how it works and what happens around the project. Here is the story:
