Creating a Bahmni Mart database for analytics

Hi, The database used in Bahmni/Openmrs has an EAV data model, and hierarchical data (For Ex: Obs table). This makes it difficult to plugin the database to any analytical tools (Tableau, Strata etc) as unstructured hierarchical data is limited and multiplies existing complexity. In order for implementation engineers to extract data from the existing production databases is said to be very difficult without totally understanding the openmrs data model. For an implementation to generate indicator…

Sync 2.0 Planning

A few quick thoughts: If we can’t use the event module for this…what exactly is the purpose of the event module? If we think the implementation of the event module is buggy, then we should fix the implementation, right? It would be nice for us to deal with hibernate interceptor messiness once, and do it properly, in the event module, and then for us to rely on that for a way to publish / subscribe to changes. Presumably, there could be an Event listener that we support which would simply h…
