What's new in JChem back-end
JChem Base is a chemical database management toolkit to handle molecules, chemical reactions and Markush structures and associated data stored in relational databases. JChem Cartridge provides similar functionality highly integrated into Oracle as well as an SQL interface to other ChemAxon products. This presentation will briefly overview the two above systems and the latest and near future developments will be introduced including; position variation queries and repeating groups, attached data and polymer representation, undefined R-atom searching, homology groups (alkyl, aryl, etc.), performance improvements, example AJAX client and Web Services interface, new metrics and other improvements for similarity search, R-group decomposition, etc.
