Object representation of relational database cells having nontraditional large object 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 and, in particular, large objects. 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 for large objects is provided so as to avoid undue burdens on performance.
