What is Journaling?

Journaling is a critical IRIS feature and a part of what makes IRIS a reliable database. While journaling is fundamental to IRIS, there are nuances, so I wrote this article to summarize (more briefly than our documentation which has all the details) what you need to know. I realize the irony of saying the 27 minute read is brief.

I've been wondering about some code that I have come across a lot over the years.

Let's assume I have class Cinema and class Film.
Conceptually the data in these classes are never really physically deleted but only flagged as such, due to business requirements.

What I find is that developers tend to create a 3rd class "CinemaFilms", in a child relationship to parent Cinema, with a reference to Film. Rather than a one-to-many between Cinema and Film.

Cache Web Terminal Release 3.1.4

Hi ISC Community!

I'm pleased to announce new release of Caché Web Terminal 3.1.4.

What's new:

1. Drag'n'drop to Studio installation: just import xml in any namespace.

2. After import and comilation access your web terminal app on URL server:port/terminal/.

F.e. localhost:57772/terminal/

Slash is mandatory.

3. No need to use %CACHELIB anymore - please feel free to update your Caché and continue using CWT.

I'm not sure how to actually interact with the result set I get from doing something like this. I want to return something like:

[{"field1":1, "field2":2}, {"field1":2, "field2":10}]

I'm finding it very difficult to get it in this format, since %Print appends a newline onto the end of the {} object it prints.

Here's the closest I've gotten:

Each business component in Ensemble picks up its allocated jobs from a pool, and the Pool Size setting for each component determines how many jobs each component can work on each time. In this article we will be specifically discussing different Pool Size settings for Business Processes.

Pool Size = 1

Imagine that your .NET project uses the Caché DBMS and you need a fully-functional and reliable authorization system. Writing such a system from scratch would not make much sense, and you will clearly want to use something that already exists in .NET, e.g. ASP.NET Identity. By default, however, this framework supports only its native DBMS – MS SQL. Our task was to create an adaptor that would let us quickly and easily port Identity to the InterSystems Caché DBMS. This work resulted in creation of the ASP.NET Identity Caché Provider.

I wanted to see some alerts that occur in my Productions in a Mobile Device, I came across Pushover.net recently that although has an upfront cost $5 you can send as many messages as you like after that, there is a 7 day free trial to check it out.

To Integrate this with a production I did the following.

Create an account and set up a device on https://pushover.net/

Record the following API Keys from the web site on the main page you will see

JSON Schema applied to InterSystems IRIS

The JSON is a data document free of types and validation rules. However, in some scenarios it is important that the JSON document has type and business rules validation, especially in interoperability scenarios. This article demonstrates how you can leverage a market-defined JSONSchema technology that is open for everyone to use and do advanced validations.

Hi Developers!

As you know InterSystems IRIS Interoperability solutions contain different elements of the solution, such as: production, business rule, business process, data transformation, record mapper. And sometimes we can create and modify these elements with UI tools. And of course we need a handy and robust way to source-control the changes made with UI tools.

For a long time this was a manual (export class, element, global, etc) or cumbersome settings procedure, so the saved time with source-control UI automation was competing with lost time to setup and maintain the settings.

Now the problem doesn't exist any more. With two approaches: package first development and usage of IPM package git-source-control by @Timothy Leavitt

I'm using cache win10-x64 version 2017.2.1.801

I want to uniquely identify the installation of cache, and from that create a meaningful unique folder names to store files.

so to generate \192-168-1-100\KEVDEV\testfolder \ and \192-168-1-5\LIVE\testfolder\

so in this case, I could- use the IPaddress and thesecond part of $SYSTEM (cache instance name) - at least this way, I can instantly see where it came from with little risk of overwriting between cache instance.

I am trying to read some binary data from a local file or through socket.

The binary data is like H.264 codec, I need to read data BYTE by BYTE (even BIT by BIT) and decide the next step based on the data read so far.

I check the documentation and it seems like most of the sample focus on human readable IO, ie: LINE by LINE.

Could I achieve my goal through COS?

Thanks.

At the end of our last lesson, we ended with our page displaying a nice (but garish) Angular Material Toolbar, and our Widget data displaying in a list of Material cards. Our page feels a bit static, and we already know that the large number of Widgets that we will be dealing with will not be especially usable on a static list. What can we do to help?

Tools for CDA/CCD?

I have a tool I absolutely love for HL7 v2 analysis and manipulation. It's called 7edit. I'm wondering if there is anything similar for HL7v3/CDA/CCD. I know it is considerably more complex, but I still have hope.

So far the best resource I've found is http://www.cdapro.com/. I'd love to hear anyone else's tips for tools or resources.

FHIR has revolutionized the healthcare industry by providing a standardized data model for building healthcare applications and promoting data exchange between different healthcare systems. As the FHIR standard is based on modern API-driven approaches, making it more accessible to mobile and web developers. However, interacting with FHIR APIs can still be challenging especially when it comes to querying data using natural language.
