MDSplus is a set of software tools for data acquisition and storage and a methodology for management of complex scientific data.
MDSplus allows all data from an experiment or simulation code to be stored into a single, self-descriptive, hierarchical structure. The system was designed to enable users to easily construct complete and coherent data sets.
The MDSplus programming interface contains only a few basic commands, simplifying data access even into complex structures. Using the client/server model, data at remote sites can be read or written without file transfers. MDSplus includes x-windows and java tools for viewing data or for modifying or viewing the underlying structures.
Developed jointly by the Massachusetts Institute of Technology, the Fusion Research Group in Padua, Italy (Istituto Gas Ionizzati and Consorzio RFX), and the Los Alamos National Lab, MDSplus is the most widely used system for data management in the magnetic fusion energy program. It is currently installed at over 30 sites spread over 4 continents.
If you are a newcomer and want to know more about MDSplus, have a look at the MDSplus tutorial.
The MDSplus developers hope that MDSplus may prove to be a valuable tool for research at your site.

November 2020: Examples of using MDSplus python objects in Julia see: Julia Example
April 2020: Web based data stream vsualization is now available. Look at the tutorial section
September 2019: jScope improvements available in the latest Stable release: Drag&Drop from jTraverser nodes to jScope panels speed the configuration process; a brand new implementation of LocalDataProvider for local data implements dynamic resampling allowing the management of very large waveforms that previously blew out the jScope JVM; command line options -l and -s<mdsip address[:port]> for local and remote data servers, respectively, provide quick network configuration. Have a look at jScope tutorial
