Abstract: A method for combining and synchronizing data in an enterprise resource planning system (ERP) with an interactive electronic technical manual (IETM) using middleware. First the middleware software receives a request for information about a product from the IETM. Then the request is processed into a request the ERP will recognize. Next the middleware software sends the processed request to the ERP. The ERP responds to the request and sends the response to the middleware software. The middleware software processes the response into a response the IETM will recognize and sends the processed response to the IETM for integration. The middleware software can also create customized IETMs from data contained within the ERP. In addition, the middleware software is connected to an original equipment manufacture's database to facilitate automatic updates of the ERP.
