# SanteDB History

SanteDB is the evolution of a reference implementation of the Canadian national digital health platform that originated in a post-secondary institution research lab beginning in 2007. SanteDB was designed with national scale, standards-based digital health applications in mind from the beginning. 

The SanteDB suite of products incorporates the full functionality of previous research products such as the MEDIC CR client registry and the OpenIZ immunization management system into a deployment-ready, commercially supported package. A brief summary of the evolution of the products is provided in the following section.  

## Evolution of SanteDB

SanteDB is really an evolution of OpenIZ ([http://openiz.org](http://openiz.org\\)) which itself was an evolution of the MARC-HI SHR RI. The table below illustrates the relative features of each solution.
