The topic

💡  Multi-model applications 💡

Develop a multi-model solution using InterSystems IRIS.

InterSystems IRIS is a multi-model DBMS. Yes, we store everything in globals, but we expose several APIs out-of-the-box which provide key-value, SQL, object, and document models of data management. And with IRIS you are able to develop your own model and expose the API which will provide some new data models, e.g. GraphDB, column-store, etc.

For this contest make an application that uses at least 2 different models to manipulate data, e.g. key-value and relational, Object and relational, DocDB and key-value.

The application should work either on IRIS Community Edition or IRIS for Health Community Edition or IRIS Advanced Analytics Community Edition.

The application should be Open Source and published on GitHub.
