This paper describes an architecture for integrating both stationary health units like hospitals and group physicians with health records of mobile health units like ambulances and doctors at emergency call service. This paper focuses on how it is possible to have high availability in all the integrated health units and at the same time keep the consistency between the health records in the different locations at an acceptable level. In central databases the consistency of data is normally implemented by using the Atomicity, Consistency, Isolation, and Durability ACID properties of a Data Base Management System DBMS Gray & Reuter, 1993. This is not possible if mobile databases are involved and the availability of data also has to be optimized. Therefore, this paper describes using relaxed ACID properties across different locations. The objective of designing relaxed ACID properties across different database locations is to make it possible for all the involved locations to operate in disconnected mode and at the same time give the users a view of the data that may be inconsistent across different locations but anyway better than the data in a centralized database with low availability for the users.
