the mobile devices. Qiwi's backend
part is installed on Dynamics NAV
(as objects) while the frontend part
is executed as an app. The device
connects to NAV via a Web Service
published by Dynamics NAV. Live
connection may be switched off,
upon which all data is downloaded to the mobile device. Once the
online connection is restored, data
is uploaded to and synced with the
NAV database.
Qiwi allows full access to NAV
business logic including data verification and form integration. Patient
data forms can be accessed and
data fields edited if required; hence
new patients or visit cards can be
added in the field, and synced with
the NAV database. Web services
allow up to 15 mobile devices per
NAV access. Fig. 12 depicts the
iPhone interface, showing a typical
display on iPad of a patient card and
a visit card, respectively.
