Nested set model for ObjectScript

In many projects I was faced with storing hierarchical data (tree) in classes.
By tree, I mean such data, where each node has a parent node — an object of the same class.
Many examples of such data can be given. For example, a catalog in the online store. Suppose that this online store sells books, in this case, the category tree might look like this:

Monospace output from Zen

Hi,

I have a problem which i think has a simple solution but which i and others haven't yet cracked. I want to display text output to a text box in monospaced font. At the moment the style sheet is shown below, I have tried various other options such as specifying a specific font such as Courier New. None of the browsers I have tried (Safari, Firefox on OSX, IE) display as monospace, although the last 2 come close. I wonder whether I need a <pre> tag, but I can't see how to do that in Zen.

Suggestions?

Atelier, The Productivity Boost Tool

Development productivity? Isn’t it kind of an oxymoron? Anyhow, we all dream a magic tool which does the tedious job of the software development and leave the intuitive or creative part on the developer. Atelier is the next generation tool of InterSystems aiming to boost the productivity of Caché/ Ensemble based software development. Atelier is based on the popular Eclipse IDE platform, which makes available the “infinite” pool of third party tools for Caché developers. Those tools can truly boost the productivity. This short article gives some examples how third party plug-ins can help developing for Caché. It is an absolute beginner’s guide, beginner to Eclipse but experienced to Caché.

Hello,

I need to access the value of a setting I created (ex: name_BO) within the logic of my BP.

Property name_BO As %String(MAXLEN = "");

/// Additional Settings 
Parameter SETTINGS = "name_BO:Basic:selector?context={Ens.ContextSearch/ProductionItems?targets=1&productionName=@productionId}";

But the class is common and the production item names will change.

As we all know, InterSystems is a great company.

Their products can be just as useful as they are complex.

Yet, our pride sometimes prevents us from admitting that we might not understand some concepts or products that InterSystems offers for us.

Today we are beginning a series of articles explaining how some of the intricate InterSystems products work, obviously simply and clearly.

In this essay, I will clarify what Machine Learning is and how to take advantage of it.... because this time, you WILL KNOW for sure what I am talking about.

The following post outlines a more flexible architectural design for DeepSee. As in the previous example, this implementation includes separate databases for storing the DeepSee cache, DeepSee implementation and settings, and synchronization globals. This example introduces one new databases to store the DeepSee indices. We will redefine the global mappings so that the DeepSee indices are not mapped together with the fact and dimension tables.

Hi InterSystems Developers!

Recently I've updated the FHIR dev template so that it now publishes an IPM package fhir-server that makes the setup of InterSystems FHIR server a trivial manual or automatic or programmatic procedure one command long.

Please see below how you can benefit from it.

TLDR

USER>zpm "install fhir-server"

All the details below.

RESTful Exception Handling

A beginner’s guide to Exception Handling in RESTful web services. The article gives an example how the various error conditions during processing a service request can be handled.

We expect our client – server communication working in a flawless operational condition, running error free software. But we are prepared to handle exceptions. Are we? So far in the examples of the previous sessions were not. We did not care about exceptions. The result? In any error incident it took ages to figure out what the problem is and more importantly how to fix it.

ErrNoResponseClass Explanation?

I'm pretty new to Ensemble and Cache, and I ran into an error today that I haven't seen before: "ErrNoResponseClass: No Response Classname is assigned for Request class <<someNumber>>". I haven't found much documentation about this beyond the Ensemble Error Codes document, which is essentially just a duplicate of the information I can see in the error message when this problem occurs. Is there any further information about this error and the conditions that cause it? Or perhaps what the <<someNumber>> value represents?

Deep see Learning

I tried to learn DEEP SEE Analytics for our HealthShare "SAMPLES" Name Space. I followed our documentation and tried it. But my management portal analyzer and visual reporting fields are hidden. So Please help me for how do I use the deep see concepts and provide some examples or demo.

Thanks ,

NewBie's Corner Session 20 Parameters and Status Part I

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Parameters

Parameters are another name for Variables when used in passing data from one Routine to another.

Let us say we have 2 routines (RtnA and RtnB), and we want to pass 3 parameters (Parm1, Parm2, Parm3) from RtnA to RtnB.

RtnA would look like:

Hello community,

I would like to know answer to the question: What would be an optimal way to connect an Ensemble and a pure Caché server? Optimally in such a way for the Caché system to be able to fire Ensemble processes and the Ensemble server to call Caché server functions.

Several $System.OBJ methods have ByRef errorlog argument:

Compile(ByRef classes As %String = "", qspec As %String = "", ByRef errorlog As %String, recurse As %Boolean = 0)

ImportDir(dir As %String = "", wildcards As %String, qspec As %String = "", ByRef errorlog As %String, recurse As %Boolean = 0, ByRef imported As %String, listonly As %Boolean, ByRef selectedlist As %String)

What's the best approach of working with errorlog?

Do you convert it to status? If so - how? Manual iteration over local?

Is there some system method to convert it into %Status?

My main goal is to be able to create reports and alerts in my SIEM based on what individual searched for and accessed what patient records, and when.

Does anybody have any experience with this? I've been ingesting audit logs in to Splunk but I'm having a hard time getting useful data.
