A conceptual database model is the primary requirement for aphysical database design. The paper discusses a conceptual databasemodel, suitable for a manufacturing or process plant when amobile device is utilised. A knowledge sharing and an e-learningmodule are suggested to be used together with the e-maintenanceapplications because of the benefits they can provide for themaintenance engineers when performing their different workstasks. Firstly, the authors briefly review the state of the art in thearea. Then the e-maintenance approach and the information needsof the maintenance engineer are discussed as well as organisationallearning and knowledge sharing are taken into account. Further,when the mobile database model is developed, it is recommendedto apply the database standards of the MIMOSA (Machinery InformationManagement Open Systems Alliance) which is worthwhileconsidering for purposes of work order and measurementevent. To conclude, there is a static view of a conceptual modelillustrated, which highlights the entities and relationship for thesurveillance of the machines as well as the most important elearningparts, for this purpose, the web mobile technology issuggested for making use of geographically distributed databasesthrough the Internet. These tools facilitate mobile e-monitoringand maintenance.
