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. See
