Node 1 and Node 2. Enter and save data onto tablet devices using the ODK Collect application.

Node 3 and Node 6. If there is internet connection, the saved data entry forms are submitted via internet to the local ODK Aggregate server that has been setup. If there is no internet connection, the data entry forms are transferred from the tablet devices onto the local server manually via cable connection.

Node 4. Monthly aggregated data should be downloaded and then shared with PIs for preliminary analysis.

Node 5 Once study is finished, download the complete aggregated data and send to PIs for final analysis.
