This article suggests to you some patterns to create REST API applications using IRIS.

Note: source code in https://github.com/yurimarx/movie

Class Pattern to the REST Application

To begin, see my suggestion for classes needed to create IRIS API applications:

• IRISRESTApplication: CSP.REST class that will be the central controller for all REST requests and responses processed by the business services.
• BusinessService: class with a business topic implementation. It can use one or more Persistent Domain Classes to persist and query data required by the business topic requirements.
• Persistent

This function is supposed to tell me that argument 1 is a valid variable name or not.

Doesn't work with an array variable, eg W $ZNAME("WLCOM(I)",0).

Not a question, just a whinge really.....

Hello Community,

we want to use a specific index on our sql-class.

The index we want to use is called "iFilter".
Currently we use the following technique of ignoring all other indices because the automatically chosen index is always too slow. 

SELECT TOP 100 d0.ID FROM %IGNOREINDEX Belegindex %IGNOREINDEX KundenNrGlobalindex %IGNOREINDEX Rechnungsnummerindex %IGNOREINDEX Erfassungsartindex %IGNOREINDEX Belegsuche %IGNOREINDEX DatumAuftragindex %IGNOREINDEX OnlineBestellnummerindex %IGNOREINDEX Belegnummerindex %IGNOREINDEX KundenNrGlobalindex %IGNOREINDEX VAMindex %IGNOREINDEX

I really love documentaries! Last weekend I was watching a Netflix documentary called This is Pop, because it was Analytics Contest time and I thought: Why not creating a pop song analytics with InterSystems Iris?

The first challenge was the database. I found on Data World project a CSV file with the Billboard hot 100 songs from 2000 to 2018, created by "Michael Tauberg" @typhon, that fits perfectly.

I was talking to @Henrique Dias and he gave me the idea of using Microsoft Power BI for good looking report with charts.

Which genres were most popular between 2000 and 2018?

Which artists had more songs

Have you heard about some restrictions in cookies for tracking visitors to your sites?

One of our clients asked me about how to know really count of visitors.

Their site works on WordPress framework, hosted on classical NAMP hosting.

They can see some statistics from Yandex Metrika conter, but we was not sure about full coverage.

We gave him the AWStats, it takes data from Apache log files on hosting.

But there were no filter of robots and hearbeat systems such as UptimeRobot or Search Engines indexing robots.

After that we decided to get data in IRIS BI for two reasons:

I regret getting a late start in the InterSystems Analytics contest. I had tried a couple of times before to use Analytics, but I had not gotten too far. I have been recording financial transactions in Excel workbook ever since I had to retire Microsoft Money. Since my iris-for-money was not fully functional, I created a worksheet per account I was tracking. I had developed a CSP page in iris-for-money to import transactions by reading a CSV file. I realized this process requires escaping many characters that can cause the process to fail.

One week ago I realized I had just two days left to

Hi Developers!

We had a set of technology bonuses for the InterSystems IRIS Analytics contest.

I'd like to share with you some storage features that also exist in Caché but are almost 
unknown and mostly not used. They are of course available in IRIS and gain importance
with large and distributed storage architectures.

I am trying to get a list of databases using the DatabaseByServer method but I am only getting an empty string. I have not found any useful examples of the proper usage of this class/method.

I have tried 2 formats. First

set dbList=""

set db=##class(Config.Databases).DatabasesByServer("my-host",.dbList)

I also tried:

set db=##class(Config.Databases).DatabasesByServer("my-host",.dbList,"/cachesys/")

In each case dbList is empty string. I can not figure out what I am missing.

Hello,

I am a clinician and we use Trakcare Lab LIMS at our institution.

We understand histopathology reports are directly typed, stored and uploaded directly to the LIMS.

For clinical audit purpose we need to download these reports directly in text format in bulk. Can anyone offer some technical assistance in retrieval of these histopathology reports? Is there any script that can be run to access, retrieve and download these reports?

Previously I have already tried to play with Google Data Studio when I connected it to InterSystems FHIRaaS. It has quite a nice UI, with a few chart types available out of the box, it can be quite easily connected to some plain tables (stored as CSV or JSON, for instance), and gives the ability to build quite flexible analytics over it. So, I have decided to implement a new connector to InterSystems Analytics (DeepSee), with the ability to select a cube and do some queries on it.

Hi Guys,

when using $ZD(mydate,4) sometimes it returns year as 4 digits and sometimes two, and the documentation is saying ([YY]YY is a two-digit year if hdate falls within the active window for two-digit years; otherwise it is a four-digit year), what active window for two means and how can I force the year to be always 4 digits ?

Thanks

Hello all,

I have a problem where one of our 3rd party systems is only able to accept HL7 messages with UTF-8 encoding but the originating messages have Windows 1252 encoding. Does anyone know a way in which I can change the encoding for the entire message from Windows 1252 to UTF-8? I have only been able to find the CONVERT method to change individual charachters but we would like to change the entire HL7 message encoding.

Thanks!

Is there an InterSystems supported dotnet core library or community contributed repo on the horizon?  At this time we are exploring installing the ODBC driver in our containers but would rather use more robust solution.

The OKR methodology (Objectives and Key Results or Objectives and Key Results) is used by the largest companies in the world (such as Google, Netflix, Spotify, BMW, Linkedin, etc.) for agile performance management. It was created in the 1970s by Andrew Grove, president of Intel, and introduced to the general public in his famous book “High Output Management”.

Around 1998 John Doerr, one of the world's top venture capitalists, after coming into contact with Intel's OKR, introduced the model to Larry Page and Sergey Brin, who started a small company called Google.

Hi,

I'm processing POP3 emails using the standard EnsLib.EMail.InboundAdapter adapter and %Net.MailMessage. I'm basically processing documents that are attached to received emails. This works fine if the document is simply attached to the email itself. But some systems are sending documents that are attached to an attached email which has content-type = message/rfc822.

How do I get the attached file from the attached email?

I'm using the following code to iterate through the email parts..
