Utilities for fast input of chemical formulae and equations.
....
***
quichem is a utility written in pure Python allowing for fast input and parsing of chemical formulae and equations. Entering data does not require any modifier keys or keystrokes to be pressed.
This SourceForge page provided pre-built Windows binaries of quichem-pyside. **To run quichem on Mac OS X or Linux**, or with the wxPython front-end, please download the source from quichem's GitHub page at: github.com/spamalot/quichem.
A universal chemistry database system, using Java and any rdbms
...The chemistry is handled using Chemistry Development Kit, this is proven code. The system holds atoms and bonds as entities in the rdbms, this makes it possible to have properties recorded using foreign keys and referential integrity. Apache Torque is used for database access. The build system of the project makes it possible to add properties directly to the molecule/atom/bond tables. This makes it more flexible than systems where structures are saved as monolithic blobs in a single table.
