Abstract

The disclosure generally describes computer-implemented methods, computer-program products, and systems for modeling and deploying decision services. One computer-implemented method includes during uptime processing: generating at least one shadow database table corresponding to a new business object (BO) persistency model, establishing change recording for at least one database table associated with an old BO persistency model, retrieving, as changed data and using at least one computer, changed BO data from the at least one database table, transforming, as transformed data, the changed data to correspond to the new BO persistency model, writing the transformed data to the generated at least one shadow database table, and retrieving, as further changed data, BO data from the at least one database table upon a determination that the BO data has changed in the at least one database table after a prior retrieval of the BO data from the at least one database table.
