Sometimes it is necessary to execute commands from the shell of the host operating system, where your ObjectScript program is located, to launch programs, operating system services, schedule crontasks, among other activities. For this, the language has a utility procedure called $ZF(-100). See:

Hi Community,

In this article I compared the features of the main leaders in the ODBMS gartner quadrant - 2019. See the list sorted by number of existent features.

Hi Community,

The Mockable.io (https://www.mockable.io/) is an online service to deploy REST API or SOAP services in seconds. This is useful to test the consumption of an API or SOAP service in your production or objectscript class without having to implement a real service, including https option.

It's very simple procedure, see:

The InterSystems IRIS has two major paths to a digital service: API/Web Service into Interoperability module and multimodel Database/Analytics. Each of them has your security configuration.

To do API security you apply an OAuth or JWT plug-in to the API endpoint. So in the Admin Portal, API producer and consumers get the keys to authenticate the API and consume it. The Admin Portal allows you configure RBAC policies too.

Web Crawling is a technique used to extract root and related content (HTML, Videos, Images, etc.) from websites to your local disk. This is allows you apply NLP to analyze the content and get important insights. This article detail how to do web crawling and NLP.

To do web crawling you can choose a tool in Java or Python. In my case I'm using Crawler4J. (https://github.com/yasserg/crawler4j).

Hi community, I used website-analyzer - an app that uses InterSystems NLP and Crawler4J to extract all website content and do NLP on it. I limited to 200 pages and discovered this:

Top 10 Concepts - business and content topics in the InterSystems site:

Other frequency concepts, see the focus in the iris speed, scale and data value:

Is it possible see the execution plan of a SQL sentence in IRIS?

Like this:

explain plan for
select  e.ename,r.rname
from    employees  e
join    roles       r on (r.id = e.role_id)
join    departments d on (d.id = e.dept_id)
where   e.staffno <= 10
and     d.dname in ('Department Name 1','Department Name 2');

That returns this:

Hi,

Do you have a guide or tutorial with recommendations to configure IRIS to a production environment? The better strategies, recommended disk, memory and processing settings, etc?

Languages like Java and C++ allows to develop a multi-threaded program with two or more parts that can run concurrently and each part can handle a different task at the same time making optimal use of the available resources specially when your computer has multiple CPUs. Is it possible In ObjectScript? If yes, Where I can get a good sample or application?
