In general, Bahmni stores data in OpenMRS recommended conventions (so there is data level integration and any OpenMRS module can understand the data that Bahmni stores and vice versa) and, sits in the same web application (so no single sign-on issues). This means to integrate any OpenMRS Reference Application App with Bahmni, we could just hyperlink between the two. We don't need tight integration between the two.

There are some variations (from the OpenMRS conventions) in the way Bahmni stores data.
