I have a class to track data changes.
As it becomes slower and slower to find last changes I think I need an index.
The 2 classes are just simplified reality.

This is the fourth article in a series on iKnow demo applications, showcasing how the concepts and context provided through iKnow's unique bottom-up approach can be used to implement relevant use cases and help users be more productive in their daily tasks. Previous articles discussed the Knowledge Portal, the Set Analysis Demo and the Dictionary Builder Demo, each of which gradually implemented slightly more advanced interactions with what iKnow gleans from unstructured data.

This week, we'll look into one more demo application, the Rules Builder Demo, in which we'll build on previous work but again climb a step on the level ladder, implementing a more high-level use case than in the previous ones. The idea came from an opportunity where we were asked to help the customer in the finance sector make sense of vast volumes of contract data. They wanted to semi-automate the extraction of logical rules from that text (in fluent legalese!), so they could be fed into other systems. While this was an exciting use case to work on (and more on it in this GS2016 presentation), we've also used it in other cases, for example to extract mentions of ejection fraction from Electronic Health Records.

Using the Java Gateway to speed development

InterSystems IRIS includes dynamic object gateways for Java, .NET, and (now) Python. These gateways allow your IRIS application to use libraries in these languages, removing the need to create everything from scratch in ObjectScript.

I am trying to determine the write-access to a windows-directory, using the method %File.Writeable(). But, this method always returns the boolean "true", even when I have revoked the write-access of Healthshare-user in this directory.

Note:
1) When the same ensemble-service tries to write a file in this directory (which it says is "writeable"), it fails.
2) The method %File.Writeable(...) works perfectly in the case of files.

Any help is appreciated.
Thanks in advance... :-)

I am just curious if someone has used this service to send Alert emails through AWS / Ensemble

I have verified 2 email ids - One to send. One to receive

Have also configured an access key for the email smtp server and added the credential to ensemble

but I get this error

ERROR #6033: Error response to SMTP MAIL FROM: 530 Authentication required.

email-smtp.us-east-1.amazonaws.com

25

So my first opinion is the authentication is not happening via the credentials settings. It needs to be passed in a different way

Hi,

I have a ZEN application that displays PDF files in an 'iframe', embedded on a ZEN popup dialog. embedded in a ZEN page running on IE 11 with its document mode set to 5, which is enough to make most reasonable people give up and start selling hot dogs in the park.

In this GitHub based on this InterSystems community rest api template Guillaume and I have created this example of all the import CRUD operations usable using ONLY Python on IRIS and using Flask.

Using the IRIS ORM or by simply doing SQL requests as both methods are seen in the GitHub.

Hello,

This package may be of interest...

Link: https://github.com/litesolutions/cachedb-import

I have programmed this over a hunch, in order to facilitate the retrieval of source code from a Caché installation. It makes use of the Java API provided by Caché.

Right now, I use it as a means to salvage sources in order to analyze them using the SonarQube plugin I develop for my employer. Unfortunately this plugin is not open source.

I am calling for help here, on two fronts:

Hi developers!

Recently we announced the preview of Embedded Python technology in InterSystems IRIS.

Check the Sneak Peak video by @Bob Kuszewski.

Embedded python gives the option to load and run python code in the InterSystems IRIS server. You can either use library modules from Python pip, like numpy, pandas, etc, or you can write your own python modules in the form of standalone py files.

So once you are happy with the development phase of the IRIS Embedded Python solution there is another very important question of how the solution could be deployed.

One of the options you can consider is using the ZPM Package manager which is described in this article.

Hi, everybody,

I've been reading some posts in the community but I haven't been able to come to a conclusion. Here's my point.

I have a cache code, and following this guide https://cedocs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?K... but I can't understand how to run this from jenkins for example, without using the console, and thus automate the process. That is to say, if it were possible to do it, what steps should I follow.

Thank you very much

HI,

I have a query like below but its syntax is not accepted by Cache.

I would like to perform a left join on two tables first and then make a inner for this result with another table.

Given the constraint that we only allow one SELECT in the query, it is possible to achieve this semantics ?

Thank for your help.

Select *
FROM ( sample . employee e
LEFT JOIN sample . company c
on c . id = e . id ) g
JOIN sample . vendor v
on v . %id = g . attr

Hi I currently have a requirement to upload microsoft documents from a client's PC to a cache database, at present the idea is to use javascript to open the file and convert it to a binary stream and then for cache csp to upload the binary stream to the database. Just wondered if anyone else had attempted this or are there better options !

Regards

Gary

Hi Guys,

Can you please advise on the below queries.

Query 1:

Example 1:

 S a="345",b="arun",c="kumar",d="hi",e="yello",f="orange"

Example 2:

S a="345"

S b="arun"

S c="kumar"

S d="hi"

S e="yello"

S f="orange"

Can you please advise me, which one is performance wise is better.

Query 2:

Example 1:

S:a=1 R="Arun"

Example 2:

I a=2 R="Arun"

Please advise me, which one is giving better performance in this.
