Four Database APIs

A concurrent session in IRIS:
SQL, Objects, REST, and GraphQL

Kazimir Malevich, "Athletes" (1932)

"But of course you don't understand! How can a person who has always traveled in a horse-drawn carriage understand the feelings and impressions of the express traveler or the pilot in the air?"

Kazimir Malevich (1916)

Introduction

We’ve already addressed the topic of why object/type representation is superior to SQL for implementing subject area models. And those conclusions and facts are as true now as they have ever been. So why should we take a step back and discuss technologies that drag abstractions back to the global level, where they had been in the pre-object and pre-type era? Why should we encourage the use of spaghetti code, which results in bugs that are hard to track down, and which relies only on virtuoso developer skills?

There are several arguments in favor of transmitting data via SQL/REST/GraphQL-based APIs as opposed to representing them as types/objects:

Hi,

is it possible to avoid the display of certain properties in a custom message class in the message viewer content section. The message class is a common Ens.Request with a bunch of properties alongside one property of Type enslib.dicom.document wich in Turn is Not extended By %XML.Adaptor so the content display of course displays an error.

My idea is to avoid the display of That certain property When output is rendered (Text/XML). Using Ens.Util.MessageBodyMethods and method %OnShowContents could be a way to do this But i don‘t find a way to do so.

(2021.1.0 isn't an option in the Product dropdown, but that's the version of HS I'm asking about!)

In the past I've used HS.Util.Installer.InstallBusDemo() to set up a local HealthShare environment (registry, edges, access gateway, etc.) I don't see an equivalent in HealthShare 2021.1. I tried importing the bits and pieces from a lower version but always seem to be missing something. Is there an equivalent utility to do a local setup in HS 2021.1?

Thanks,

Lori

Google has one intersting tool named Data Studio. This tool allows creating some interactive dashboards, based on your data, available from the internet. It already offers hundreds of connectors to any sort of data developed by the community. As well as some amount of community developed visualizing. And most importantly, Google offers a way to develop your own connector to your data.

FHIRaaS provides a REST API, and it's available from the internet. So I've decided to try to create some basic report on data stored there. And in the end, I got this.

Introduction

In the first article, a simple tutorial helped you to set up your FHIRaaS deployment.

Now, let's move forward and introduce a JS library to access the FHIR resource.

In the end, two examples of usage of this library will be presented, exploring the Appointment FHIR resource type.

SMART on FHIR JavaScript Library

FHIR is a REST API, so you can use any HTTP client in order to use it. But, it’s always a good idea to have help.

FHIRaaS overview

Introduction

This article aims to provide an overview of InterSystems IRIS FHIR Accelerator Service (FHIRaaS) driven by the implementation of application iris-on-fhir, available in OEX developed for the FHIRaaS contest.

A basic tutorial will guide you in configuring a function FHIRaaS deployment, including an API key and an OAuth 2.0 server.

A library to use FHIR resources through FHIRaaS also is briefly discussed.

Is there a way to add/substract from a pivot variable?

I have this MDX:

SELECT
  NON EMPTY [DateOfSale].[Actual].[YearSold].&[$variable.Year] ON 0,
  NON EMPTY [Product].[P1].[Product Name].Members ON 1
FROM [HOLEFOODS]

And with pivot variable Year equal to, say, 2016 it works:

Now I want to add previous year first with one pivot variable and one explicit reference. It also works:

I've poked through the class documentation and globals and I can't seem to find what I'm looking for, namely a mechanism that will give me the PropName key and value for each of the Items in an EnsLib.HL7.SearchTable definition. Is there some sort of query that will turn the list of Items in the XData SearchSpec section into a key/value pair of some sort?

For example:

Question
· Jun 1, 2021
Storing a %DynamicObject

I've been tasked with an interface that needs to supply some additional metadata for the indexing of HL7v2 messages. After toying with a couple of ideas, I thought that it would be useful to subclass EnsLib.HL7.Message, add a %DynamicObject property, and store the metadata in it (it ends up getting sent to the target in JSON form anyway).

And, well, it seems to work just fine ... so far.

Hello,

We have a need to track Database changes over time - down to the SQL level of granularity if possible. Such as: User xyz runs routine ^abc and we get something similar to a changelog that tells us: table A had this value updated, insert, update etc....

Is that possible using IRIS level tools (Audit Log, Journal File, etc...) , is there a way to convert the global sets and kills from the journals into SQL level changes?

    Hi community,

    I am in the process of building a React Native Application for a restaurant.

    I am not quite sure if we can use IRIS as the main database for this and if there is a possibility I am not quite sure how to do it.

    If there is a possibility could some one help me out with it please?

    Or do you think using AWS is a better choice?

    Please let me know your ideas and guidelines in the comments or please feel free to reach out to me directly.

    Hoping to hear soon.

    Regards.
