= Input and output =

DataMelt supports many different types of I/O (input-output), in most cases the I/O part of DataMelt is 
based on self-descriptive file formats.  Here is the list of I/O supported by DataMelt:

* The native Java I/O. Access them from the '''java.io''' package;
* The native Python I/O methods and classes;
* Native DataMelt I/O classes which are built-in into the JHPLOT package (will be discussed below). Several packages based on the standard Java serialization and XML-type  serialization. Access them from '''jhplot.io'''. We will discuss some of them below;
* External databases  such as:   
* SQL-type (Derby and SQLite based on  [http://sqljet.com/ SQLjet])
* Object-based databases (like [http://www.neodatis.org/ NeoDatis] and several other)
* External file formats native to C++, such as ROOT and AIDA
* Google's [http://code.google.com/p/protobuf/ Protocol Buffers library] which is fully integrated, thus all DataMelt Java data containers can be accessed or written using C++ program (or any other which are supported by the Protocol Buffers).
