**<u>The topic</u>**

Globals or direct data access - is the heart of InterSystems IRIS persistence engine. All the IRIS data that could be accessed via SQL, REST-API, ObjectScript, DocDB, or Native API is stored in globals.

[Globals engine](https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=GGBL) is responsible for the performance, reliability, and scalability of InterSystems IRIS.

In this contest, we invite everyone to contribute open source applications that will use InterSystems IRIS globals to read, store and change the data. We invite you to use the power of globals to leverage the performance of data ingestion and reading along with the flexibility of storage schema that lets to introduce arbitrary data model implementations.

We are pleased to invite all the developers to the upcoming [InterSystems Globals Contest Kick-off Webinar](https://www.eventbrite.com/e/intersystems-globals-contest-kick-off-webinar-tickets-301399061707)!
