Abstract
One aspect of the invention is a method for maintaining persistence in a shared object system. A request is received to update a persistent record of a shared object's state wherein the persistent record of the shared object's state is contained in a database. At least one SQL statement is dynamically generated in response to the request. That statement is generated using a data structure comprising data reflecting at least a portion of the state of the shared object and a map associating attributes to the shared object with the location of those attributes in the database. An SQL statement is then sent to the database.
