Hello,

searching messages in our Message Bank is quite slow, often runs into timeout.

I wanted to perform a tune table on Ens_Enterprise_MsgBank.MessageHeader because this apparently has not been done yet - the Tune Table utility shows no entries for selectivity, etc.

I tried

w $SYSTEM.SQL.Stats.Table.GatherTableStats("""Ens_Enterprise_MsgBank"".MessageHeader")

and got this error message

Hello all; I am using a one-to-many relationship. I have a Claim (one), in a relationship with Lines (many), but the Claim is storing a list of Lines IDs, rather than the Lines storing the Claim Id. This seems upside down, and not what I expected.

Hi Devs!

Is there a way to get a Global that contains pesistence data for a class?

In early versions of IRIS it was classname_"D", like ^Sample.PersonD. Now, at least in IRIS 2022.1 it is something random.

Hello everyone, I’m a French student that just arrived in Prague for an academical exchange for my fifth year of engineering school and here is my participation in the interop contest.

I hadn’t much time to code since I was moving from France to Prague and I’m participating alone, so I decided to make a project that’s more like a template rather than an application.

This GitHub is the simplest way to scrap using IRIS and Python, all of that already incorporated in an IRIS PRODUCTION.

From here you can build any IRIS production in full Python or in ObjectScript as this module is interoperable.

In this GitHub we fine tune a bert model from HuggingFace on review data like Yelp reviews.

The objective of this GitHub is to simulate a simple use case of Machine Learning in IRIS :
We have an IRIS Operation that, on command, can fetch data from the IRIS DataBase to train an existing model in local, then if the new model is better, the user can override the old one with the new one.
That way, every x days, if the DataBase has been extended by the users for example, you can train the model on the new data or on all the data and choose to keep or let go this new model.

Before we start talking about databases and different data models that exist, first we'd better talk about what a database is and how to use it.

A database is an organized collection of data stored and accessed electronically. It is used to store and retrieve structured, semi-structured, or raw data which is often related to a theme or activity.

At the heart of every database lies at least one model used to describe its data. And depending on the model it is based on, a database may have slightly different characteristics and store different types of data.

To write, retrieve, modify, sort, transform or print the information from the database, a software called Database Management System (DBMS) is used.

The size, capacity, and performance of databases and their respective DBMS have increased by several orders of magnitude. It has been made possible by technological advances in various areas, such as processors, computer memory, computer storage, and computer networks. In general, the development of database technology can be divided into four generations based on the data models or structure: navigational, relational, object and post-relational.

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?

Can I please check if anyone know why the data base resource is created differently when creating a namespace after specifically selecting it to use the default resource %DB_%DEFAULT?

I created a namespace and when creating the DB I selected the option to use the default resource

When the namespace creation was complete , database is using a new resource instead of the default.

Hi,

I'm trying to load some data into IRIS using LOAD DATA in the IRIS terminal however I am getting blocked by this error. I have read the documentation on this page trying to set up a gateway connection but get the same Connection cannot be established error.

This is what is in the %Java Server activity log

This formation, accessible on my GitHub, will cover, in half a hour, how to read and write in csv and txt files, insert and get inside the IRIS database and a distant database using Postgres or how to use a FLASK API, all of that using the Interoperability framework using ONLY Python following the PEP8 convention.

Hi

Does anyone know where the user generated code resides, the stuff one might write for a production, I presume it lives in a table somewhere within a database?

Basically, I want to do some dependency analysis of what I've written - find out what's in use, how it's referenced, etc. I know I can export it to an XML file and work on that, but direct access on a table would be quicker for me.

Cheers

Hi,

I'm very new to InterSystems Health Connect so may be doing something silly...

I'm trying to link to an Oracle DB view using the Link Table Wizard in the Management Portal. The wizard finds the view, but when I select it and click the 'next' button I get an error on the 'Select Columns' screen: 'ERROR #5534: Columns error' (and no columns show in the wizard). I've tried on several views and tables in the same DB but keep hitting the same error.
