What are best practices for JSON transformation in IRIS interoperability? This is for a non-healthcare use case, so any tools we happen to have around FHIR might not be available. The motivating use case is trimming down a verbose and needlessly complex REST API response to feed to an LLM - trying to reduce token usage and maybe get better results from less noisy data.

Been testing out the Production Validator toolkit, just to see what we can/not do with it. Seems really interesting and there seem to be some use cases for it that can really streamline some upgrades (or at least parts of upgrades) but I was running into so many hurdles with the documentation. I am curious if anyone else has used it.

Let's suppose two different routines use one and the same chunk of code. From the object-oriented POV, a good decision is to have this chunk of code in a separate class and have both routines call it. However, whenever you call code outside of the routine as opposed to calling code in the same routine, some execution speed is lost. For reports churning through millions of transactions this lost speed might be noticeable. Any advice how to optimize specifically speed?

Minify XML in IRIS

In a project I'm working on we need to store some arbitrary XML in the database. This XML does not have any corresponding class in IRIS, we just need to store it as a string (it's relatively small and can fit in a string).
Since there are MANY (millions!) of records in the database I decided to reduce as much as possible the size without compressing. I know that some XML to be stored is indented, some not, it varies.

Hello,

Our software commonly returns a full result set to the client and we use the DataTables plugin to display table data. This has worked well, but at datasets grow larger, we are trying to move some of these requests server-side so the server handles the bulk of the work rather than the client. This has had me scratching my head in so many ways.

I'm hoping I can get a mix of general best practice advice but also maybe some IRIS specific ideas.

Some background

InterSystems has corrected a defect that causes invalid database and journal records to be introduced when using a specific $LIST syntax. The likelihood of encountering this defect is very low but the operational impacts can be significant.

We are using the IRIS cloud. and I am working on a DTL .

so the source side timestamp is local time for example 20240110134740, I know it is a local time. so the requirement is I need to append the UTC at the end, like -0400 or -0500 depending on if it is daylight saving time.

so is there function to return if current day is at daylight saving time, so I can decide if I need to append the -400 or -500? or a function to return the current UTC by location?

Hello everyone,

I am new to Deepsee (BI intelligence) concepts in IRIS. I am looking for a solution of below question

Question: We have a server where we are currently storing archive PDF reports of our application.

We want to add and view these archive reports (PDF format only) in dashboards. Is there any way we can do this? Or any article which can help us performing this task.

Thanks in advance!!

I am trying to finish build for moving to IRIS HealthShare Health Connect 2022.1 from HealthShare Health Connect 2018.1.3. I am currently using Delegated Authentication using an AD group to match up to the Role in IRIS. The Role has access to everything but the HS Resources because we don't really use the HS Resources for anything. We are mainly using IRIS for the Interoperability Engine.

Hello,

Thank you for reading this question, and thank you for your time and replies.

I was wondering which ways, tools, mechanisms, or vias would you recommend to teach to kids, teens, adults, being your sons / daughters or not; your passion or likelihood for programming and computers?

I know there are some programming free games like the following ones:

While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together.

Intersystems provides External language server connections for various languages which,
from a development perspective, is great as I can keep my application code separate but still interact with the IRIS kernel.

It becomes more complex though if you are using Interoperability etc where you might end up with some code in IRIS and some code in another language.

What would be great is having an IRIS to IRIS language server where the application code and stay IRIS based but separate from the database?

Polybase and IRIS

Hi all, I am trying to use Polybase in SQL Server 2019 to access an external Cache/IRIS Database. I have followed the initial steps of enabling Polybase, creating a Database, DB scoped credential and then an External Data Source. These steps have not caused any issues and appear to be successful, I am using the same DSN we use for a Linked Server connection that works normally. I am running into an Error when trying to Create an External Table. The error is a generic Native Code 469 "Driver Not Capable".
