if you learned c++ in a computer science program you learned about data structures. Oracle has really 2 general types. Balance(B*)Tree index and Bitmap(truth table).
descriptions of Balanced Trees are in any Computer Science 2 book, not sure what level bitmaps are taught though.
dont understand it in terms of c++ code, think of it in terms of structure. Received on Thu Feb 13 2003 - 02:35:14 CET
