We then chose to explore OpenMRS, which is a well-known open-source enterprise electronic medical record
system platform [7]. OpenMRS has a very extensive and elaborate set up to customize to suit the business need of
an enterprise. Solar Ear wanted to experiment OpenMRS but was overwhelmed with the multitude of features, the
inherent complexity and the technical knowledge needed to add fields to the database. OpenMRS needed changes in
the database for it to store the information Solar Ear required. Though OpenMRS comes with a pre-built set of
fields, there were other fields needed by Solar Ear such as the readings for left ear and right ear. Solar Ear was
looking for a simple and sustainable solution which made us rule out the OpenMRS option and move to ODK
Collect and ODK Aggregate. Open Data Kit (ODK) is a set of free and open source tools which help organizations
author, field, and manage mobile data collection [8].While the ODK tools are very intuitive and communicated well
with one other, the difficulty was that Solar Ear wanted the option to send details via SMS at locations where there
is no internet or Wi-Fi connectivity.
