I wrote a step by step tutorial in the qewd-howtos repository how you can write state of the art multi-page web apps with Node.js using a QEWD-Up WebSocket/REST api back-end integrated with a mainstream web framework like NuxtJS & Vue.js.
I am happy to share with you my first experience of using a docker container version of IRIS for Health to explore your interest in using or having a trial by taking the advantage of a docker container that is lightweight, and easy to deploy. This cookbook will go through the implementation steps using the GitHub repository called ENSDEMO written by Renan Lourenco.
When we are at the starting stage of BI project development, we must remember that it is crucial to select the right tool for its implementation. Today we want to show you how one of the principal functionality of dashboards is implemented in different BI systems. Let's talk about drill down from both points of view: the dashboard development, and the convenience and clarity for the end user. We will touch on the applications of this technology in IRIS BI, Power BI and Tableau.
With the gradual improvement of hospital information construction, there are more and more business interfaces in hospitals. Due to the influence of various factors (network, consumer system, etc.), the data processing of business interface may cause excessive message accumulation and even the situation of interface card congestion, which affects the normal business development in the hospital. Therefore, the monitoring of the queue of business interface components becomes more and more important.
According Wikipedia a mind map is a diagram used to visually organize information into a hierarchy, showing relationships among pieces of the whole. It is often created around a single concept, drawn as an image in the center of a blank page, to which associated representations of ideas such as images, words and parts of words are added. Major ideas are connected directly to the central concept, and other ideas branch out from those major ideas.
I recently participated in a fantastically organized hands-on by @Patrick Jamieson in which an Angular application was configured together with an IRIS FHIR server following the protocols defined by SMART On FHIR and I found it really interesting, so I decided to develop my own Angular application and thus take advantage of what I learned to publish it in the Community.
SMART On FHIR
Let's see what Google tells us about SMART On FHIR:
The idea of this package is to compare the performance of columnar storage inside IRIS without wrapping it to some foreign platform that is not my world
In addition, I do not want to measure network performance between 2 containers, but inside a closed IRIS environment that I have fully under my control
Even the use of SMP or some other browser-based presentation has some influence that I want to avoid.
CCR users can now take advantage of an enhanced syntax for substituting pre-defined tokens with live URL links within phase-related text fields. In addition to the existing <env> token which automatically updates to reflect the Environment of the relevant CCR Record, CCR now introduces three new keywords: <smp> , <smpPrefix> , and <homepage>.
Let's go with the last article on how to record yourselves for the Article Contest video bonus.
I'm not going to go into how to do very specific things in editing because it varies depending on the program you use. The keyboard shortcuts and menus are different, but the concept is the same. You are going to use a programme to organise the recorded material, remove the excess and give it structure. Many of these softwares are free (Capcut, Canva and if I'm not mistaken DaVinci had a free version). I've been editing with Adobe Premiere for almost ten years now (wow, I'm getting old), so if you have any questions about this software, feel free to write to me.
I thought I'd share some issues I had today with Zen development in a custom component. Say we have created a Zen composite component with a few javascript methods that modify its child components. In order to modify these components, we can use something like the following method:
Say you have a global in one database that you instead want to map from a different database. If you just create a global mapping to the new database, the existing global will become inaccessible because it still lives on the old database. The documentation notes this problem here but doesn't give details on how to fix it.
In the first article I started discussing RESTForms - REST API for your persistent classes. We talked about basic features, now, I'd like to discuss advanced features - mainly queries capabilites:
Basic queries
Query arguments
Custom queries
Queries
Queries allow getting slices of data, based on arbitrary criteria. There are two query types in RESTForms:
Basic queries work for all RESTForms classes once defined and they differ only by the field list
Custom queries work only for the classes in which they are specified and available, but the developer has full access to query text
One of the most important features during application development is the ability to debug your code easily. Because of the asynchrnous nature, a standard Node.js application server works single-threaded by default. When you are developing applications using an IDE like Visual Studio Code, you can very easily debug your Node.js process:
This code snippet changes all passwords in a system to a specified string. The two literal strings at the beginning of the snippet can be adjusted to edit the system or password string. The class method "test" runs the code:
The goal of this article is to give users of InterSystems products background on source control in general, and how it can be used with Atelier, an Eclipse plugin. Specifically, I'll be discussing what to do when all of your developers share a single dev instance of an InterSystems product where they can edit and compile code.
One of the features I like in InterSystems ObjectScript is how you can process array transformations in a specific method or a function.
Usually when we say "process an array" we assume a very straightforward algorithm which loops through an array and does something with its entries upon a certain rule.
The trick is how you transfer an array to work with into a function.
One of the nice approaches on how to pass the information about an array is using $Name and Indirection operator.
Below you can find a very simple example which illustrates the thing.
We use the Caché JDBC Gateway to Oracle and SQL servers to directly invoke their stored procedures from Ensemble. Getting quick, inline data results back are typically handled within the Functions.Library class as a function to wrap the query and format the return appropriately.
In my article I described the work using iris.gref . As the official documetation is rather slim on the subject it was necessary to dig into it. Using the power of Python I was able to detect what I needed but was hidden. I decided to share this with you. pydoc did the magic.
I was using PowerBI to create regular display data obtained from one popular web sourse with hundreds of thousands of visitors per month and a big number of users.
At the beginning of that visualisation development, I was using direct connection from Power BI to Adaptive Analytics powered by AtScale. Adaptive Analytics is useful for cached data, aggregates and fast data sources switching between development and stage phases. The “AtScale cubes'' connection method was used:
Surely you wanted to use the OpenAPI Specification (OAS) JSON you used for your spec class on the iris-web-swagger-ui iris package. The generated OAS from the ##class(%REST.API).GetWebRESTApplication(...) method is very crude, with no description on the parameters or the expected response structure.
So after creating your REST application from an OAS you should have:
InterSystems IRIS is a high-performance data platform designed for developing and deploying mission-critical applications. It is a unified data platform that combines transaction processing, analytics, and machine learning in a single product.
