Open Source Data Management Systems

Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other quantum chemistry programs. Files can be transferred directly from several databases, including RCSB, EDS, NCI, PubChem, and MaterialsProject. Multiple files can be loaded and compared. A rich scripting language and a well-developed web API allow easy customization of the user interface. Features include interactive animation and linear morphing. Jmol interfaces well with JSpecView for spectroscopy, JSME for 2D->3D conversion, POV-Ray for images, and CAD programs for 3D printing (VRML export).

Viking is a free/open source program to manage GPS data. You can import, plot and create tracks, routes and waypoints, show OSM, Bing Aerial and other maps, geotag images, create routes using OSRM, see real-time GPS position (not in Windows), make maps using Mapnik (not in Windows), control items, etc. It is written in mostly in C (with some C++) & the GTK+3 toolkit. Viking is currently dual managed - with a corresponding Github presence at: https://github.com/viking-gps/viking Where you may find it easier to view the code and raise issues there too.

ReportServer is a modern and versatile open source business intelligence (BI) platform with powerful reporting features. With ReportServer you are not limited to one provider's solutions. ReportServer integrates Jasper, Birt, Mondrian and Excel-based reporting: choose what best suits your needs! The source code is also available in GitHub: https://github.com/infofabrik/reportserver ReportServer scripting samples: https://github.com/infofabrik/reportserver-samples

Viewmol is a graphical front end for computational chemistry programs. It is able to graphically aid in the generation of molecular structures for computations and to visualize their results.

This project is a LED Strip Light Organ implementation using the Arduino framework.

MAED is a simple but powerfull math program with educational character. It has a Lisp like programming language, a nice GUI. It can work in client-server mode. A main goal is to make a program which can solve math problems using both numerical and symb

It's a developer system which work with graphical source code.

GpsPrune is a java application to view and manage coordinate data, eg from GPS units. With it you can load a variety of text and Xml formats, view the data (in 2d and 3d), edit and convert the data, correlate photos and audio, create charts and more.

SSF aims at providing an easy to use and efficient framework for physics sim & visuals in small scientific simulations in real-time, as well as games, which are inherently real-time applications.
