Hi, Community!

I'm pleased to announce that in this December 2017 we have 2 years of InterSystems Developer Community up and running!

 

Together we did a lot this year, and a lot more is planned for the next year!

Our Community is growing: In November we had 3,700 registered members (2,200 last November)  and 13,000 web users visited the site in November 2017 (7,000 last year).

Thank you for using it, thanks for making it useful, thanks for your knowledge, experience, and your passion!

And, may I ask you to share in the comments the article or question which was most helpful for you this year?

Happy Birthday, Developer Community!

Hi

I have an Ensemble Application with many classes and relationships between those classes.

I need a tool that can connect to Cache/Ensemble and create a visual ERD from the class definitions within a particular Cache Namespace

MS-Access is one option but it does not automatically create the relationship connectors between classes

Any suggestions

In the HL7 Annotations available in the Management Portal,  at the message type and message structure levels, there are columns for 'Explicit Usage' and 'Implicit Usage'.  In nearly all cases, the values in these two columns match, but at least for message types RAS and RGR, they don't.

What's the meaning of explicit and implicit in the annotations?

Thanks,
Liz

This post is intended to guide you through the new JSON capabilities that we introduced in Caché 2016.1. JSON has emerged to a serialization format used in many places. The web started it, but nowadays it is utilized everywhere. We've got plenty to cover, so let's get started.
