  "definition": "1. A Chemical Relational Database (CRD) application is a specialized relational database application that imports and exports standard format SDF files, and that includes both a graphical chemical structure field in addition to data and text fields. CRDs generally have chemically intelligent structure-searching functions that allow a user to search records using generalized structure queries (e.g., based on atoms, atom and bond type, structural fragments, etc.) in addition to searching across data and text fields. DSSTox does not provide an on-line CRD capability for searching DSSTox SDF files, but provides information on a variety of commercial and public CRD application options available to users. More on CRDs (http://www.epa.gov/ncct/dsstox/MoreonCRDs.html).\n\n2.
