#!F-adobe-helvetica-medium-r-normal--18* #!N #!CSlateBlue #!N #!Rdatachp Working with Data Model Objects #!N #!EC #!N #!N This chapter describes the programming interface for creating and manipulating the basic Objects of the Data Explorer data model (some Objects are discussed in later chapters). For a brief summary of the data model, see #!Lprogchp,dxall984 h Overview #!EL . For a detailed description, see #!Ldatmod,dxall197 h Understanding the Data Model #!EL in IBM Visualization Data Explorer User's Guide. #!N #!N Data Explorer is an object-oriented graphical application. Its objects are data structures in global memory, they are passed by reference, and their contents are private to the implementation.
