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.

Helpful resources

1. Resources on models:


1.1. Globals (key-value)

Globals are sparse multidimensional arrays that could be stored and managed within the IRIS database. You can deal with Globals using ObjectScript and Native API.





1.2. SQL access

InterSystems IRIS provides SQL access to data using via ObjectScript/REST API and ODBC/JDBC.





1.3. Object Access

InterSystems IRIS provides the way to store and change instances of objects in globals via ObjectScript/REST API, Native API for Java/.NET/Node.js/Python, and XEP for Java/.NET.


1.4. Document Access

InterSystems IRIS provides DocDB to store and manage JSON data documents via REST API and ODBC/JDBC(SQL).

One of the things you can do is to implement a new data model, after all InterSystems IRIS gives you a lot of freedom in data handling. For example, check this community projects:

You can add something else or improve existing MongoDB/Redis implementations

if you're a JavaScript/Node.js developer, you can use the QEWD-JSdb abstractions of IRIS: 

- Document database

- Persistent JavaScript Objects

- Redis-like Lists

- Redis-like key/object store

- Persistent XML DOM (with XPath querying)


Take the introductory tutorial:

and then delve into the other database models:

A whole world of multi-model opportunities to explore for this competition!
