Object aggregation representation of relational database rows having nontraditional datatypes

摘要

A program product is described in which a class library is provided to permit object oriented applications to access and to manipulate, in accordance with the object model, nontraditional data values of a relational table. Nontraditional datatypes of a relational table include multimedia and large object datatypes. The data is manipulable by virtue of extended data objects that each represent a cell of a relational row, and that each inherit type-specific behaviors from the class library. Special handling is provided for large objects.
