This tutorial is a follow on to Working with %Query It was displaying the content of the input stream chopped in fixed-size chunks. But often those streams are structured and have well-defined separators (e.g HL7) So as a side subject of this tutorial, this chapter shows how to break a stream into PIECES.
It is exactly the same idea as the $PIECE() function for strings with some add-ons.
My previous article introduced you to the COS based Custom Class Query. There were some features missing like more lines of the stream displayed and numbered.
My previous article introduced you to SQL based Basic Class Query where a clever wizard created all the required code for you and your essential contribution was an SQL statement.
Now we enter the real Custom Class Query thatprovides more freedom but requires a deeper understanding of the mechanic behind the scene. The full code example is again on GitHub
The title of the contest subject is not quite precise but addresses the %Library.classes involved. What is meant is officially named Class Query and is dating back to the early days of Caché. CLASS is used because it is embedded in a COS class. Though there is a precise description in the official documentation it remains rather abstract. My tutorial should guide you step-by-step through a simple example in COS to make it tangible to you
You are experts in IRIS and know all tricks. The functionality of $ZF(-1,-2,-100, ......) is nothing new to you And you know the limits of this functionality. Both give you access to your local server command line environment. And that's it.
Large language models are stirring up some phenomena in recent months. So inevitably I was playing ChatGPT too over last weekend, to probe whether it would be a complimentary to some BERT based "traditional" AI chatbots I was knocking up, or rather would it simply sweep them away.
There is not just one class in this package: rcc.gstream.cls but also rcc.gstreamT.cls
While rcc.gstream works with direct access to the stream globals, the *T version uses a Process Private Global (PPG) as Temporary storage. using SELECT * FROM RCC.gstreamT WHERE RCC.useT('^jpgS')=1 and similar.
Predictable storage IO performance with low latency is vital to provide scalability and reliability for your applications. This set of benchmarks is to inform users of IRIS considering deploying applications in AWS about EBS gp3 volume performance.
Summary
An LVM stripe can increase IOPS and throughput beyond single EBS volume performance limits.
Before I begin my writing journey here I wish to introduce myself briefly, so that everyone who reads and follows me will get a clear picture.
To start with I did my Bachelors in Physical Sciences, Mathematics and Computer Science were my core subjects. I have 4+ years of experience in HealthCare Revenue Cycle operations including Medical Coding, Billing, AR Collections, Denial Management and Fincial Reconciliation. Also, 2+ years of experience in Data Operations and Analytics, specifically in Python, PowerBI, SQL and MsExcel.
Hi! Today I would like to talk about one of the most important architectural patterns in Angular.
The pattern itself is not related to Angular directly, but as Angular is component-driven framework, this pattern is one of the most essential for building modern Angular applications.
Container-Presentation pattern
It is believed that good components should be small, focused, independent, testable and most important - reusable.
Before we start with some intermediate and advanced topics, I would like to sum up some more general points. They are subjective, of course, so I will be happy to discuss them if you have other opinion or better arguments for any of them.
The list is not comprehensive and this is intended, cause I will cover some topics in future articles.
Hi! My name is Sergei Sarkisian and I’m creating Angular frontend for more than 7 years working in InterSystems. As the Angular is very popular framework, our developers, customers and partners often choose it as part of the stack for their applications.
I would like to start series of articles which will cover different aspects of Angular: concepts, how-to, best practices, advanced topics and more. This series will target people who already familiar with Angular and wouldn’t cover basic concepts. As I’m in the process of building articles roadmap, I would like to begin with highlighting some important features in most recent Angular release.
Hi! As a developer who was forced to move from Mac to Windows (temporary) I found some things a bit confusing. In this article I would like to talk about some tweaks I made to make my experience smoother. I think it can help not only Mac users who need to use Windows environment (for ex. in VMs), but also can help some Windows users to make some things more convenient. Of course, all the points are subjective, the best setup is one that works for you.
All the tweaks are related to Windows 10 as I don’t have an access to Windows 11 at the moment.
M:N Relationship is a recurring object of my interest for a long time. So the subject turns up with me repeatedly. For this article, I found a nice example with TWO separate M:N relationships. Some M:N².
It is not pure fiction but taken from a closer view of OEX Contests that we run on a regular base.
Wanted to have a FHIR Story in the back pocket to share with the participants on a dead simple series of calls against the FHIR Server for anybody in the mindset of emitting metrics from a device to FHIR.
The final day of the Hacking Health Camp 2022 in Strasbourg, France, is upon us and today we will see all the wonderful creations of the teams. They worked hard through the night and our teams onsite and online worked with them and answered their questions.
As you can see in my profile I teach at a university and I wanted to share my take on teaching IRIS (or Caché before it).
It’s been some time but I remember seeing a series of articles by @Yuri Marx earlier this year about the course “Developing with InterSystems Objects and SQL”. He actually gave a brief description of what’s done on Day 1, Day 2, and Day 3 with comments from instructor @Joel Solon. And I thought to myself, it may be interesting to share my experience.
Finding errors in your code or examining unexpected behavior is the main purpose of Debugging I will try to refresh the traditional tools away from the helpers you have in Studio, VScode, Serenji, .... to the basics which have been there before your preferred EDI used it in the background.
Just in case you never heard about OFX before V1 was an attempt to create a dedicated SGML for banking and ignoring XML. Details. It evolved to XML but not for M$ MONEY. Today we would use JSON for similar tasks.
During the last weeks, I was working on various issues and problems related to SW development. I found that quite often problem analysis was mostly chasing issues just on the surface but not really attacking the deeper reasons of the problem and follow the consequences. It's like the doc that stops your leg bleeding but doesn't see that it is broken.
I'd like to share with you some storage features that also exist in Caché but are almost unknown and mostly not used. They are of course available in IRIS and gain importance with large and distributed storage architectures.
