Lightweight Histogram Interface Layer

Speaker:
Charles Leggett
A troubling theme that pervades modern data analysis tools available
in the world of high energy and nuclear physics today, is that the
user is usually constrained to a specific platform and file format.
PAW, ROOT, and HepTuple are all culprits in this regard. Furthermore,
modern tools such as ROOT, JAS and OpenScientist seek to blend the
lines between data analysis tools, and visualization tools, which
often should be kept discrete, requiring the use of large libraries.
We present a statistical data interface layer, which treats histograms
and ntuples as discrete, lightweight objects, allowing simple
manipulations, and the ability to either save the objects in
traditional file formats such as hbook or ROOT, or to pass them on to
applications. This functionality is provided by a class library, that
can be linked to existing code with minimal modifications, enabling
the histogramming of virtually any data type.
