  Hospitals are distributed across geographical areas and it is important for
all hospitals to share information as well as integrate their systems for
effective researching and health delivery. Health personals and institutions in
need of information from hospitals with respect to geographical areas can
easily do researches on patients, treatments, disease outbreaks, and effects of
drugs. This research work is aimed at integrating of database systems of
hospital across geographical areas via a service bus. A centralized service bus
was used to facilitate interoperability of applications across platforms and
enhance communication within the hospital infrastructure as well as creating
enabling environment for new layer of abstractions to be added without
modification of the entire system. Concept of Service Oriented Architecture
with web services was used for rapid integration solution in solving the
challenges faced during integration of multiple incompatible applications.
