The use of Source Code Control systems in development is important. And there are a few systems known in the world, like GIT, SVN (Subversion), Perforce, Mercurial. Where the most popular nowadays is the git. Using it is very useful in many cases, but mostly it depends on the code as text, which can be compared between commits, branches, or versions of releases and so on.

IRIS vs Other integration engines

Hello All,

I have been using IRIS / Ensemble for over a decade and appreciate lot of it's functionalities and features, however besides having a UI of 80's era (which doesn't bother me), what I believe where IRIS is lacking is lack of out of the box connectors (services/operations).

If we look at IRIS's competitors for eg Mulesoft, Talend, Boomi they all have hundreds of pre-built connectors for major applications like Salesforce, SAP etc and cloud services like Azure, AWS etc to store and retrieve information and data.

Hi Devs!

A few months ago I raised a discussion on the naming convention for ZPM modules.

And you free to put your name or your organization name for the packages you want to have your personal or company's brand.

But if you contribute to community, we suggested to have "community." package for all such libraries.

But the name is too long.

Hi Community! Many of you have seen the Data Points podcast episodes that we have been releasing since February. I mentioned previously that I planned to pose an open question to the community about topics you might like to hear in a podcast episode. Let us know in the comments if there are any conversation points you would find particularly interesting, and we can try to include some conversations with experts on said topics!

And in case you missed it, check out Episode 12 about the all-new chat bot on InterSystems websites!

Application licensing enables InterSystems application partners to take advantage of Caché’s licensing capabilities for their own licensing purposes.

Caché manages customer application licenses just as it does Caché/Ensemble and InterSystems application licenses, maintaining usage counts and acquiring and returning user licenses as needed.

Application licenses consumed by a process or a CSP session are automatically released along with the Caché license consumed by the process or session when a process exits, halts or is deleted from the process table, or when a CSP session times out or is deleted.

More in docs.

Do you use this feature? If so, how?

I'm especially interested in license validation and general workflows?

Hello Everyone ,
Good Day !
I have a question regarding the implementation of USCDI (US Core Data for Interoperability).

Why USCDI was introduced?
What is the disadvantage of previous process ( communication between systems using concept like HL7) ?
What is the impact of implementing this concept in existing systems ? Do we have to change logics for processing the messages?
Will it effect the existing work flow of all the healthcare application?

What does everyone think about submitting an issue in a repository and then submitting a pull request to fix that issue. Is it an unnecessary step or does it give extra context and logging for the issue? I ask this because when I find a bug in an Open Exchange app, I always submit the Issue and then often submit a Pull Request to fix the issue.

I think that if the repository owner doesn't like your suggested fix, it is helpful to have the issue around so that they can deny the pull request and potentially implement their own change for the issue.

I'm not sure what the purpose of this is, but the Management Console causes the browser to refresh periodically. If you're in a form or an editor such as the DTL or Routing Rule editors, you may lose work unless you save frequently. This did not occur in Caché 2018 and earlier releases.

I've had a couple of incidents where I've created a number of rules in the DTL editor, answered the phone or stepped away for a few minutes, then come back to find any work since the last save erased.

I've noticed this in both 2019 and 2020 releases of IRIS.

Heads up!

Hi,

we're planning some work on our SQL Query Plan functionality for a future release of InterSystems IRIS and are interested to hear how you're using them today, or what'd keep you from using them. Rather than try and fit everything in a rigid survey, I thought a simple thread on our beloved DC might also reveal some use patterns that we support or could do a better job on.

Hi All,

We have few queries which are simple selects . For simplicity let's say there is a query that joins two tables and gets few columns and both tables have no indexes.

Select Tab1.Field1, Tab2.Field2
From Table1 Tab1
Join Table2 Tab2
On Tab2.FK = Tab1.PK

When we do query plan for this it shows approx 6 million, however if we make a simple adjustment to the query

This is a lesson learned, which I would like to share with community.


Recently I ran into an issue, where I was using %ConstructClone and it kept cloning extra records, which were not needed. The record for which I was trying to run a clone had many-to-one relationships.

The solution to this issue was using param -1. If you run %ConstructClone(-1) it will not clone relationships, but rather just clone single oref as desired in this case.


I hope this information helps someone who is working with similar records.

Hi Developers!

Often we need to use relatively small arrays with constants, static arrays in algorithms, etc where we need to do something with each element of an array. There are several ways to deal with it in ObjectSctipt.

Previously I used to use globals, locals, PPG for this but not so long time ago figured out that %List is a way too handy.

Indeed, suppose we have an array of months and need to set up and use it in our code.

HI,

I am planning to build a WebApp that will have tons of data to display in tables, ability to add comments on that table rows and may be some few more small features as we move on.

1. It has to be Secure

2. It has to be fast

3. It has to be Non CSP / Non Zen

4. Will have Cache DB to pull records from but should be flexible to do that from any odbc resource

5. Version 2018 Ensemble

My first step would have been to investigate different options for technologies that would make it work and best suited with Ensemble 2018

Hello, InterSystems community!

Lately, you have probably heard of the new InterSystems Package Manager - ZPM. If you're familiar with it or with such package managers as NPM, Dep, pip/PyPI, etc. or just know what is it all about -- this question is for you! The question I want to arise is actually a system design question, or, in other words, "how should ZPM implement it".

Hi Community!

Sometimes I meet a method which accepts 10+ parameters.

And often I need only the 8th parameter to pass. And I call the method something like:

do ##class(Some.Feature).Method(,,,,,,,"flag")

And I don't like this method when I call it like this cause, you know, often I just miss the number of commas and raise some other flag I wanted.

How do you avoid this situations?

If you meet such a code, how do you call it and sure that you didn't miss the number of ","?

What is a good number of parameters in a method and f you need to pass more parameters in a method what do you do?

Hi Developers!

InterSystems IRIS stores everything in globals and if we use ObjectScript classes to persist data class documents globals it uses in storage. But if you use globals for calculations, temporary storages, for special indexes or for some other purposes - how do you document it?

Possible options which come to my mind:

1. Macro

#define Array ^MyGlobal

usage:

s $$$Array(1)=1

2. Class parameter

Parameter Array ="^MyGlobal";

Usage:

CodeGolf: FizzBuzz

Let's have a round of CodeGolf!

As usual the goal is to write the shortest solution for a specified problem.

Today we have one of the classics: FizzBuzz.

Write a program that prints the numbers from 1 to 100.

But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”.

For numbers which are multiples of both three and five print “FizzBuzz”
