In a computing system, an operation is performed on an instance of a data object. One of several persistence models that are available for the data object is identified for the instance using the performed operation, where each of the several persistence models defines how the data object is to be persisted in a database. The instance is stored in the database according to the identified persistence model. The persistence model may be identified at run time in a manner transparent to a user. A first persistence model may be identified for a first instance of the data object and a second persistence model, different from the first persistence model, may be identified for a second instance of the data object. An object instance may later be stored according to another persistence model. |
