A very important task performed by MSDQuery is to generate PDB files, used by nearly all external application programs at this time. Because PDB files are generated automatically from the MSD, our PDB files are consistent across the resource - a critical need for effective use of the data as a collective whole. In the future the separation of conceptual and physical layers means that data can be stored in a variety of database models. There is no dependence on a legacy system. As a consequence of this database architecture, the impact of changes at the conceptual level are well defined at the physical level.
Entries become dynamic rather than static.
The inconsistency in level of detail reported for structures in the current PDB is of major concern and must be rectified in current entries and avoided in new entries. Dynamic behavior should not be interpreted as affecting the integrity of an entry. Evolution of an entry presents no technical barrier.
