In recent years, Grid Computing has become a key technologyin resource integration and sharing, thus improvingscientific collaboration among different institutions. Whilesome applications need access databases spread across theparticipants of the grid, OGSA-DAI is middleware that enablesdatabase integration and sharing from different vendors.By using replication techniques, this work aims toprovide a higher level of availability and reliability whenusing databases exposed to the grid. It defines an architecturefor systems that want to offer replication to the grid andwe implemented extensions to the OGSA-DAI middlewarein order to achieve this objective and prove the concepts ofthe proposed architecture. This paper presents the resultsobtained in the implementation and an initial study of itsapplication in a Health Care Information System.
