The data is in the segments of objects (data segments, index segments, rollback segments, and so on)
The level of logical database storage above an extent is called a segment
index tree is a is a balanced index tree data structure optimized for cases where both the index and the actual data are fully kept in memory
A tree structure is a way of representing the hierarchical nature of a structure in a graphical form. It is named a "tree structure" because the graph looks a bit like a tree, even though the tree is generally shown upside down compared with a real tree; that is to say with the root at the top and the leaves at the bottom.
