7. RPMS-EHR (Component Framework)
A government open source application.
The Component based framework allows for development without affecting VA/IHS components.
Can map RPMS Globals to SQL tables for modernized data manipulation or web front ends.
Components can be developed and implemented within the EHR client applications.

8. RPMS EHR Weaknesses - Not intuitive..
Certainly requires a greater learning curve than most commercial platforms.
Decades of development that lacks structure, logic, and odd dependencies. -Deciphering logic gives developers headaches.
Reports: outdated process of generating a canned report that spits out to a printer or to view on a terminal window. Now days we need charts, graphs, something to visualize the data.
Interfacing to commercial systems is always a question.
Written in MUMPS (even though many commercial systems do still reside on a MUMPS backend much of the front end and dev modules are something newer like c#
Power Hungry… RPMS requires a lot of memory, and a solid state or NVME SAN is a great idea as well.

9. RPMS EHR Strengths
- Flexible. Proper development can greatly improve the usefullness.
Customizable. Sky is the limit.
Cost effective – As compared to Commercial systems.
Robust. This is a very comprehensive system with decades of development focused for Indian health.
Quick! (on the right hardware, Client side and server side)
Intersystem DBMS. The Intersystems Enseble DBMS is best of breed.
Quality Data.

10. Custom Development Projects
