Detailed Description

To store large quantities of same-class objects, ROOT provides the TTree and TNtuple classes.

The TTree class is optimized to reduce disk space and enhance access speed. A TNtuple is a TTree that is limited to only hold floating-point numbers; a TTree on the other hand can hold all kind of data, such as objects or arrays in addition to all the simple types.
