Abstract
A method, apparatus and article of manufacture is provided for mapping persistent data objects residing in multiple data sources into a single, reusable software component accessible to an object-oriented programming language application performed by the computer, for multi-database access to data that may be physically distributed and stored in disparate DBMSs, each stored in an electronic storage device coupled to the computer. The method has steps for identifying data objects in multiple data sources, employing a multi-database software facility for connecting to the data sources containing the data objects, and registering the data objects with the multi-database software facility, creating a single virtual data object consolidating multiple attributes from the registered data objects, and establishing a connection to the multi-database software facility for referencing the virtual data object as though it was a single real data object. It also has a step for wrapping this virtual data object as a reusable software component accessible directly from object-oriented programming language applications.
