Contents of databases are translated into objects by reading the database schema metadata to determine data interrelationships and create objects with nominal human to computer interaction. Metadata for any number of databases is normalized in a standardized view. Skeleton code templates representative of final classes to be produced are accessed and merged with the standardized view. Source code for the class of the objects is then generated. At runtime, data objects are then produced by encapsulating the metadata and data values. Communication between database instances and a client computer consists of metadata and database row values., Rows from database tables and the corresponding metadata are transmitted from the server to the client computer in one logical network operation. The final distributed objects are then assembled into the optimal format required by the client computer. To update, delete or create new persistent objects, the reverse process occurs.
