Hi folks!

Sometimes when we develop a mockup or PoC there is a need for a simple interface that will provide data in IRIS in JSON against SQL queries.

And recently I contributed a simple module that does exactly that:

accepts SQL string and returns the JSON.

How to install? Just call:

zpm "install sql-rest"

If you install it in a namespace X it will setup a /sql endpoint to your system that will accept POST requests with SQL string and will return the result for you for the data available in the namespace X.

Challenges of real-time AI/ML computations

We will start from the examples that we faced as Data Science practice at InterSystems:

  • A “high-load” customer portal is integrated with an online recommendation system. The plan is to reconfigure promo campaigns at the level of the entire retail network (we will assume that instead of a “flat” promo campaign master there will be used a “segment-tactic” matrix). What will happen to the recommender mechanisms? What will happen to data feeds and updates into the recommender mechanisms (the volume of input data having increased 25000 times)? What will happen to recommendation rule generation setup (the need to reduce 1000 times the recommendation rule filtering threshold due to a thousandfold increase of the volume and “assortment” of the rules generated)?
  • An equipment health monitoring system uses “manual” data sample feeds. Now it is connected to a SCADA system that transmits thousands of process parameter readings each second. What will happen to the monitoring system (will it be able to handle equipment health monitoring on a second-by-second basis)? What will happen once the input data receives a new bloc of several hundreds of columns with data sensor readings recently implemented in the SCADA system (will it be necessary, and for how long, to shut down the monitoring system to integrate the new sensor data in the analysis)?
  • A complex of AI/ML mechanisms (recommendation, monitoring, forecasting) depend on each other’s results. How many man-hours will it take every month to adapt those AI/ML mechanisms’ functioning to changes in the input data? What is the overall “delay” in supporting business decision making by the AI/ML mechanisms (the refresh frequency of supporting information against the feed frequency of new input data)?

Previewing Server Manager 3.0 for VS Code

The InterSystems Server Manager extension for Visual Studio Code lets you define connections to your servers, list their namespaces and edit or view code there. You can also launch Portal for a server.

Server Manager 3.0 improves security by becoming a VS Code Authentication Provider. It is my entry for the November 2021 InterSystems Security Contest. Click here to visit the contest page where you may decide to vote for this entry. Please ignore the clickable "Contestant" label on this article header above, as it relates to a different contest for new DC articles. If you want to support me in that contest, simply "like" this post.

We’ve already considered how to run an IRIS-based application in GCP Kubernetes in Deploying InterSystems IRIS Solution into GCP Kubernetes Cluster GKE Using CircleCI. Additionally, we’ve seen how to run an IRIS-based application in AWS Kubernetes in Deploying a Simple IRIS-Based Web Application Using Amazon EKS. Now, let’s look at how to deploy an application to the Azure Kubernetes Service (AKS).

Previously I had published The Article about the dataset from a real webserver, which can demonstrate how can activity and load of the Apache webserver depends on day of week, search engines indexing and some network noise.

Now I want to describe one useful function for most of webmasters and system administrators who are interested in obtaining of exactly information about visitors, hardware usage, and also about errors that gaing to their clients.

Here it is

echo %ERRORLEVEL%

rem note that we need to check errorlevel from highest to lowest here....

if errorlevel 5 goto OK

Presenter: Stefan Wittmann
Task: Take advantage of the NoSQL paradigm without adding another tool
Approach: Provide sample use cases that are an excellent fit for InterSystems’ new document data model
 

Description: Designing applications always requires you to make assumptions about your data model. Come to this session to learn how you can effectively handle the cases where you have to rapidly evolve your model. We will also discuss other use cases that are an awesome fit for the flexible document data model.

Problem: I’ve observed the NoSQL landscape and like the direction, but I have no use-case that fits and I do not want to add yet another tool.

Solution: InterSystems now has support for a well integrated document data model that brings the NoSQL paradigm to the enterprise within your current stack.

Task: Build a composite application that bridges data silos
Approach: Give a real-world example of combining data from multiple sources to run a composite application
 

Most organizations need to bridge silos of data or combine separate applications. This session describes techniques for building composite applications and silos. The session also looks at a real application that does this. It uses workflow to assign cases to individuals for investigation and extracts information from multiple systems to provide the investigator with a complete context for the case at the scene of the incident.

Atelier, The XML Contents Editor

This article is one of the series which introduces Eclipse to experienced Caché/ Ensemble/ HealthShare users. The goal is to open the perspective of a developer who was using Caché Studio for years and make Her/ Him see deeply into the Eclipse world – far beyond Atelier. In other words it is an Atelier (Eclipse IDE for InterSystems technology) beginner’s guide. This time the topic is: editing XML files using Atelier.

Have you ever needed a math function but could not find what you needed and ended up writing your own? Look no further! ObjectScript-Math is here to solve all your math related function needs.

ObjectScript-Math is an Open Source library for ObjectScript Math functions. It is now available on Open Exchange. This library contains a mix of new functions that are not currently available and functions that are available. The existing functions will be wrapped for use from ObjectScript-Math so that all Math functions can have a central location.

This library will continue to grow, so give it a try and give your feedback!

Don't see what you are looking for? Please feel free to submit requests for additional functions or contribute code yourself!

Hi developers!

Suppose you have a Github repository with ObjectScript classes but without a Docker environment.

Recently I published a repository with a set of files that form a universal Docker and VSCode environment to let you either import and run your repository in InterSystems IRIS Community Edition on Docker or turn your repository into Docker and VSCode environment for InterSystems IRIS Community Edition.

So in one sentence:

Unpack these files in your folder and you have the Docker and VSCode environment for your InterSystems IRIS ObjectScript application!

See the details below.

If you work with interoperability productions of InterSystems IRIS or Ensemble, no doubt you are familiar with the Message Viewer page. The page supports filtering messages according to filter criteria you enter in the Basic and/or Extended Criteria sections. Extended Criteria conditions are specified as property-operator-value triples. Once you click Search button, such triples become WHERE clause conditions of a generated SQL query executed against message header/body tables.

Now available on Open Exchange is a library of third party charts available to use within DeepSee/InterSystems IRIS BI dashboards. To start, simply download and install, select the new portlet as the widget type, then select the chart type that you desire. If you don't find the type of chart you are looking for, you can easily extend the portlet to implement your desired chart type. These new chart types can be used within existing dashboards or you can create new dashboards using them.
