Hi @Raman Sailopal 

You can publish your contribution on OpenExchange 

Check out this video about ZPM, so you can provide your command line in an even easier way to install and use it.

Hi @Sharafath.Fazil 

I never worked with React Native, but I developed something in Flutter a few years ago.

In my humble opinion, it doesn't matter that much since I'm assuming you'll be consuming data using a REST service to interact with flutter/react-native applications. 

It's up to you :) 

Maybe taking into consideration the pros and cons of each one of them.

Hope that helps.

Hi, 

Could you share your code with us?

Hi @YURI MARX GOMES

Hi @John Lisa 

You can use IRIS Management Portal. There is a built-in tool to extract information using SQL.

The Path is: System Explorer > SQL 

Inside the SQL Explorer, you can change to your preferred Namespace and have access to your tables, as you can see in the image below:

Hope that helps.

Best Regards, 
Henrique

If you want to develop/design reports. Jasper Studios is what you looking for.

Free and simple

Hi, 

If you want to try J-Report, here is a link for the trial version: 

https://www.jinfonet.com/product/download-jreport/

For an OpenSource alternative, you can take a look at Jasper Reports Community Edition 

https://community.jaspersoft.com/

I used to work with Jasper Reports to generate PDF reports for my customers. To connect to InterSystems IRIS, use the ODBC and voilá.

As mentioned by @Carmen Logue , if you tell us your reporting requirements, that should be easier to discuss alternatives.
