Structural (topological) Databases The structural databases play a central role in chemistiy because they contain information on chemical stmctures. Examples of this type are CAS registry, National Cancer Institute (NCI) database, Crystallographic Stracture Database (ICSD), CSD, Protein Data Bank (PDB), etc. The structure databases are usually designed to store chemical stmctinal information representing the chemical bonds and atoms in such a way to use them for computational operations, such as structure search, data mining, etc.
