Task: Use the FHIR standard with HealthShare-based solutions
Approach: Provide an overview of how HealthShare will support the evolving FHIR

The next major release of HealthShare will be the first version to support the emerging HL7 FHIR standard. This presentation will discuss InterSystems’ involvement with the FHIR standard, detail the new FHIR functionality, and review our long term plans for FHIR in the HealthShare platform.

Content related to this session, including slides, video and additional learning content can be found here. Please note that this content is available only to HealthShare customers and attendees of the Global Summit. On the learning web site you will be prompted for your Global Summit credentials to access this content.

Let's say we have two serial classes, one as a property of another:

Class test.Serial Extends %SerialObject
{
Property Serial2 As test.Serial2;
}

Class test.Serial2 Extends %SerialObject
{
Property Property As %String;
}

And a persistent class, that has a property of test.Serial type:

Class test.Persistent Extends %Persistent
{

Property Datatype As %String;

Property Serial As test.Serial;

}

So it's a serial, inside a serial, inside a persistent object.

Artificial intelligence is not limited only to generating images through text with instructions or creating narratives with simple directions.

You can also make variations of a picture or include a special background to an already existing one.

Additionally, you can obtain the transcription of audio regardless of its language and the speed of the speaker.

So, let's analyze how the file management works.

Generating OFX [V1]

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.

Tutorial - Streams in Pieces

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.

Task: Provide failover for distributed systems without using a VIP
Approach: Demonstrate using InterSystems’ database mirroring with external traffic managers such as F5 LTM/GTM

With distributed environments and even public cloud environments, the use of a VIP sometimes is not desirable or even possible given network topology or deployment. The session will demonstrate integrating database mirroring with external traffic managers such F5 LTM/GTM using API based triggers in InterSystems products to interface with the F5 appliances. This not only presents automated redirection for the local mirror members, but also provided automated client redirection to asynchronous DR mirror members.

Method or Class Method?

For programmers new to ObjectScript, one question will inevitably arise: “What is the difference between methods and class methods?” A typical answer would be: “A class method applies to a class, but a method applies to an instance of that class.” While that answer is correct, it lacks important information on how these methods di

Portal tip: Feel at home on the Home page

Until recently I didn't pay much attention to Portal's home page:

If it's not showing when you initially launch Portal you can easily jump to it using the button / tab at the top of the left-hand column of options. And later during your session, get there via the Home link that will be visible at the top of every page.

On the Home page the "Recent" section is automatically maintained for you.

Hi folks!

Sometimes when we develop a mockup or PoC there is a need for a simple interface that will provide data in IRIS in JSON against SQL queries.

And recently I contributed a simple module that does exactly that:

accepts SQL string and returns the JSON.

How to install? Just call:

zpm "install sql-rest"

If you install it in a namespace X it will setup a /sql endpoint to your system that will accept POST requests with SQL string and will return the result for you for the data available in the namespace X.

Hi community!

I want to introduce you a new powerful feature from our static code analyzer objectscriptQuality.

Each time a new IRIS version is released, you need to prepare a roadmap for migration in which you need to spend a lot of time on testing to find where your code is not accomplishing with the newer version. Or maybe you need your code to be compatible with multiple IRIS or Caché versions.

Suppose you have an application that allows users to write posts and comment on them. (Wait... that sounds familiar...)

For a given user, you want to be able to list all of the published posts with which that user has interacted - that is, either authored or commented on. How do you make this as fast as possible?

Here's what our %Persistent class definitions might look like as a starting point (storage definitions are important, but omitted for brevity):

Hello Community,

SQL language remains the most practical way to retrieve information stored in a database.

The JSON format is very often used in data exchange.

It is therefore common to seek to obtain data in JSON format from SQL queries.

Below you will find simple examples that can help you meet this need using ObjectScript and Python code.

Hi ObjectScript developers!

How to Protect Your Belongings from Pests While Moving - Delicate ...

InterSystems ObjectScript is perhaps the best language on the planet to deal with globals - and it is an interpretable language.

Yes, it has a compiler. But even the compiler can compile some lines in ObjectScript which will then fire as bugs during the runtime.

There are some technics on how to avoid that such as unit testing, coding guidelines and your coding experience, of course ;)

Here I want to present to you the yet another approach to how you can reduce the number of errors in your ObjectScript runtime and enforce coding guidelines - it's an ObjectScript Quality tool developed by Lite Solutions, InterSystems solution partner.

See the details below.

GlobalToJSON-Efficient

I have created a package that offers a utility to load a Global into JSON object and reverse
to create a Global from this type of JSON object. Efficient refers to the structure created.
Only Globals nodes containing data are presented in the generated JSON object.

Dear community members!

A very common problem of our users is to use an external database as data source in an IRIS production. As many of you already know, we have two ways to connect directly to an external database, the first one is using an ODBC connection, the second is using JDBC.

In our example we are going to create a connection using JDBC, and we are going to build a simple Docker's project, in this way you will be able to modify the example as you wish.

Creating and listing XData definitions

Hi InterSystems Community!

The ObjectScript language of InterSystems IRIS has the ability to extend classes using a very interesting feature called XData.

It is a section in your class that can be used to create custom definitions to be used within the class itself and also externally.

To create one or more XData definitions for your class is very easy, see the example:

I've been working for some days in the connectivity between NodeJS client applications and IRIS as server using web sockets.

You can get all the information in relation to the web socket connections using IRIS as a client or as a server from this URL: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls...

InterSystems FAQ rubric

To resolve the error <PROTECT>, remove the read-only attribute of the system-wide library database (IRISLIB for InterSystems IRIS, CACHELIB for Caché/Ensemble/HealthShare (Caché-based))

Once you have finished importing the routine, remember to change it back to read-only.

[Version 2013.1 and above]
[Management Portal] > [System Administration] > [Configuration] > [System Configuration] > [Local Database] Uncheck "Mount read-only" from the database name link.

The time that many of the Developer Community members, InterSystems Partners, and just people interested in InterSystems products, had been looking forward to has arrived! Finally, after an excruciatingly long pause, this year's Global Summit is again held in person! This time it's in Seattle! A beautiful city with steep hills, breathtaking views of Elliot Bay, and, from the words of locals, constantly bad weather cheeky
