This is the fourth in a series of releases that are part of the developer preview program for 2022.2 Future preview releases are expected to be updated biweekly and we will add features as they are ready. Many updates, fixes and enhancements have been added in 2022.2, in SQL management, cloud integration, Kafka and JMS adapters, the SQL Loader, and other areas.

Hey Developers,

In July, you posted 83 questions on Developer Community:

And now it's time to announce the Key Questions of July, chosen by InterSystems Experts!

Hey Community,

Here is a digest of the Developer Community videos on InterSystems Developers YouTube Channel in July 2022:

Hi team,

I'll start with an apology as I am trying to wrap my head around the architecture of how InterSystems IRIS database management works. I am attempting to connect to the platform remotely through say a JDBC or ODBC connection in order to run queries, searches (through SQL statements) on my laptop and was trying to understand whether this would be possible? It is possible to setup an inbound client connection and wanted to better understand the architecture of how the database association works for IRIS database management. Does it use it's own internal SQL database or are we able to connect to our own database and which databases are certified to run against the platform?

How to convert from internal date format to JSON/Web date format: YYYY-MM-DDTHH:mm:ss (example: 2012-04-23T18:25:43)?

Hi guys,

Does rebuilding of Data Quality Manager cubes affect patient index linkage definition data?

What I want to understand is, does DQM have any negative impact on the data each time you rebuild the cubes.

Additionally, if I make changes to the cube and rebuild it..will this have any impact on the original data?

Hi Guys,

Is there online tutorials or samples on how to use Inbound Adapters ?

All I'm looking for at this stage is to create and inbound Adapter in a production to request to connect to a client where I can Get JSON file and what do I need to establish the connection?

Thanks

Hi Developers!

We have great new articles for your to read and enjoy, thanks to our wonderful participants of the 3rd InterSystems Tech Article Contest: Python Edition!

🌟 12 AMAZING ARTICLES 🌟

And now it's time to announce the winners!

Let's meet the winners and their articles:

Hi, we are trying to run a dynamically generated Oracle Insert SQL script using Do $SYSTEM.SQL.DDLImport("Oracle",""," sql.txt",[Error Log]) to insert multiple rows into a Linked Table within HealthConnect to an Oracle database.

We have tried using statements that are accepted within Oracle but not when using Intersystems DLL along the lines of :

Continuing to observe the possibilities of Django, and usage with IRIS. The first we have looked how to define models and connect to tables already existing in IRIS, than we extended embedded Django Administration portal, with an ability to see what data we have in that models, with filters, editing and even pagination.

Time to go to real action, now we a going to create some REST API, on Django, based on the same data, we used before from the package posts-and-tags.

To do so, we will use Django REST Framework

Django REST framework is a powerful and flexible toolkit for building Web APIs.

Some reasons you might want to use REST framework:

• The Web browsable API is a huge usability win for your developers.
• Authentication policies including packages for OAuth1a and OAuth2.
• Serialization that supports both ORM and non-ORM data sources.
• Customizable all the way down - just use regular function-based views if you don't need the more powerful features.
• Extensive documentation, and great community support.
• Used and trusted by internationally recognised companies including Mozilla, Red Hat, Heroku, and Eventbrite.

Your application is deployed and everything is running fine. Great, hi-five! Then out of the blue the phone starts to ring off the hook – it’s users complaining that the application is sometimes ‘slow’. But what does that mean? Sometimes? What tools do you have and what statistics should you be looking at to find and resolve this slowness? Is your system infrastructure up to the task of the user load? What infrastructure design questions should you have asked before you went into production? How can you capacity plan for new hardware with confidence and without over-spec'ing? How can you stop the phone ringing? How could you have stopped it ringing in the first place?

In the first part, I've shown how to start a new project on Django, as well as define new models and add already existing models.

This time, I'll introduce an admin panel, available out of the box and how it can be useful.

Important note: do not expect that if you try to repeat actions from this post it will work for you, it does not. During the article, I had to do some fixes in the django-iris project, and even in DB-API driver made by InterSystems to fix some issues there as well, and I think this driver is still in development, and we will get more stable driver in future. Let's decide that this article only explains how it could be if we would have all done.

I was wondering if someone could help me. I do not have docker available to me however a lot of the Open Exchange apps require it. Since I am using a Virtual Windows Machine I can not get docker installed, so I was wondering how to get around this? Someone at GS2022 suggested looking at the docker_compose.yml to figure out how to get around docker, but I am not sure I understand how to read it.
