Java Analysis Studio (JAS) is a desktop data analysis application aimed primarily at offline analysis of high-energy physics data. The goal is to make the application independent of any particular data format, so that it can be used to analyze data from any experiment. JAS features a rich graphical user interface (GUI) aimed at making the program easy to learn and use, but which at the same time allows the user to perform arbitrarily complex data analysis tasks by writing analysis modules in Java.
JAS can be used either as a standalone application, or as a client for a remote Java Data Server. The client-server mechanism is targeted particularly at allowing remote users to access large data samples stored on a central data center in a natural and efficient way. JAS is written entirely in Java and will run on any platform with a Java virtual machine.
This talk will describe JAS, including the enhancements in release 2.0, and some of the modular components that can be used outside of the JAS framework. In addition we will give example of the use of JAS for Babar Online Monitoring and Linear Collider Detector (LCD) Physics studies, including a discussion of the experience of creating and using a complete LCD reconstruction package in Java.
