To synchronize databases between disparate data processing environments, a buffer, which is part of a first data processing environment having a first database, is loaded with a database update. Loading the buffer does not commit the database update to the first database in the first data processing environment. A remote function is called in the first data processing environment to apply the database update to a second database in a disparate second data processing environment. In response to the remote function determining that the second database has been successfully updated with the database update, the database update is committed to the first database. In response to the remote function determining that the second database has not been successfully updated with the database update, the database update is rolled back in the buffer such that the first data processing environment is unaware of an attempted update to the first database.

Synchronization of dissimilar databases

A method, system and computer-readable medium for synchronizing databases between two disparate computer systems are presented. In one embodiment, the method includes updating a first database, which is part of a first computer system, with a database update, wherein updating the first database does not initially commit the database update to the first computer system; calling a remote function to incorporate the database update into a second database that is part of a second computer system; in response to the remote function determining that the second database has been successfully updated with the database update, committing the database update to the first computer system; and in response to the remote function determining that the second database has not been successfully updated with the database update, rolling back the database update such that the first computer system is unaware of the attempted updating of the first database.

A method of optimizing communication and processing functions between disparate applications includes sending, from a first application to a disparate second application, a request message. The request message, which has a reduced data size for optimizing communication, is formatted in a first request-format to provide unique data elements relevant to processing the request message. The received request message is reformatted into a second request format, and is then forwarded to a third application. The third application creates a response message that is in a first response format, and sends the response message to the second application. Each received response message is queued, by a messaging application, into a response message collection corresponding to a message type, before sending the response group to the first application.
