A system is disclosed for serving a message to a target system. A database message is converted to a common data model to conform to at least two systems and an architecture of the target system. The common data model is transformed into a specified data type of the architecture of the target system. Calls are managed using specified functions available through an application programming interface offered by the architecture of the target system. Functions of the application programming interface are invoked to implement a target message in the architecture of the target system. The message is written to the target system.
