SHORT DESCRIPTION

DataMelt is a software environment for numeric calculations, statistics and data analysis

DataMelt, or DMelt, is an environment for numeric computation, data analysis and data visualization. DMelt is designed for analysis of large data volumes ("big data"), data mining, statistical analyses and math computations. The program can be used in many areas, such as natural sciences, engineering, modeling and analysis of financial markets.

DMelt is a computational platform: It can be used with different programming languages on different operating systems. Unlike other statistical programs, DataMelt is not limited by a single programming language. Data analysis and statistical computations can be done using high-level scripting languages (Python/Jython, Groovy, etc.), as well as a lower-level language, such as JAVA. It incorporates many open-source JAVA packages into a coherent interface using the concept of dynamic scripting.

DMelt creates high-quality vector-graphics images (SVG, EPS, PDF etc.) that can be included in LaTeX and other text-processing systems. The program runs on Windows, Linux, Mac OS.

## History[edit | edit source]

DataMelt has its roots in particle physics where data mining is a primary task. It was created as jHepWork project in 2005 [1] using the Java software concept for International linear collider project developed at SLAC. Later versions of jHepWork were modified for general public use (for scientists, engineers, students for educational purpose) since the International Linear Collider project has stalled. In 2013, jHepWork was renamed to SCaVis. In 2015 it became a community-supported project and was renamed to DataMelt.

DataMelt is hosted by the jWork.ORG portal[2].

## Documentation[edit | edit source]

In 2018, DataMelt web page hosted about 600 examples written in Jython, Java, Groovy, JRuby, covering a number of fields, from general mathematics to data mining and data visualization. The Java API documentation includes the description of more than 40,000 Java classes. The DataMelt documentation includes certain restrictions for general public due to the proprietorial nature of the documentation project.

jHepWork was described in the book "Scientific Data analysis using Jython Scripting and Java" [3]. Later it was also discussed in the German Java SPEKTRUM journal [4]. More recently, the DataMelt program was described in the book [5]. According to the Springer International, this book was top 25% most downloadable books in 2016 and 2017 in the category "Advanced Information and Knowledge Processing".
