Speaker: Naomi TakashimizuWe have implemented a software package for histogramming. Histogram objects are stored in the database, and are exchangeable between C++ and Java program. Using this package, one can store and retrieve histograms in and from the database in analysis programs coded in either C++ or Java.
Java is a simple language which is designed to be object oriented. Some complicated features in C++ are excluded, especially the exclusion of the pointer free programmers from the memory management. Architecture-neutral bytecodes generated by Java compiler enable applications to be transported efficiently to any platforms. An efficient development in Java can be possible for non-professional programmers such as physicists.
The package also implements a histogram visualizer, which can access to both C++ and Java objects, including the functionality of interactive operations such as addition, subtraction, fitting, changing bin width and so on.
Histogram objects are stored in Objectivity/DB in the current version, however, other object persistent manager will be considered for support.
