ROOT ROOT is an OO framework for large scale scientific data analysis and data mining. It has been developed at CERN with the sponsorship of HP and is currently being used by a number of large high energy physics experiments. The ROOT system, written in C++, contains, among others, an efficient hierarchical OO database, a C++ interpreter, advanced statistical analysis (multi dimensional histogramming, fitting and minimization algorithms) and visualization tools. The user interacts with ROOT via a graphical user interface, the command line or batch scripts. The command and scripting language is C++ (using the interpreter) and large scripts can be compiled and dynamically linked in. Using the PROOF (Parallel ROOT Facility) extension large databases can be analysed in parallel on MPP's, SMP's or loosely coupled workstation/PC clusters. ROOT also contains a C++ to HTML documentation generation system using the interpreter's dictionaries (the reference manual on the web is generated that way) and a rich set of interprocess communication classes allowing the transfer of complete objects from one process to another.
