The Air Force maintains several disparate databases to support maintainability and sustainability of aircraft and aircraft engines, e.g., CETADS, CEMS, REMIS, JOAP, and IETMS. These databases, however, have been implemented in a stove piped configuration where they don't share, exchange, or integrate data with any sort of automation. It is not uncommon to manually export, email, and either import or manually reenter the data into a complementary database. This can be time consuming and error prone. Additionally, it is too cumbersome to develop Reliability Centered Maintenance tools, algorithms, and reports with this architecture and process. We are proposing the development of a methodology to integrate this disparate data as a means of producing a data warehouse which can support RCM tool development. The level of transparency of this data integration will depend upon the DMBS used, their connectivity, security, and even integrity of the data. All aspects of the listed systems will be review and considered prior to developing the integration methodology. The resulting processes and tools developed have wide application in commercial areas such as medical records and industrial maintenance, as well as other DoD organizations who suffer from, "too many databases which don't talk to each other
