(DDM) An IBM data protocolarchitecture for data management services across distributedsystems in an SNA environment.DDM provides a common data management language for datainterchange among different IBM system platforms.Products supporting DDM include AS/400, System/36,System/38 and CICS/DDM.On the AS/400, DDM controls remote file processing.DDM enables application programs running on one AS/400system to access data files stored on another systemsupporting DDM. Similarly, other systems that have DDM canaccess files in the database of the local AS/400 system.DDM makes it easier to distribute file processing between twoor more systems.OS/400 Distributed Data Management V3R6 Reference(http://as400bks.rochester.ibm.com/cgi-bin/bookmgr/bookmgr.cmd/BOOKS/QBJALH00/CCONTENTS).

Platidiam
- An inorganic water-soluble platinum complex. After undergoing hydrolysis, it reacts DNA produce both intra interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity cisplatin correlates with cellular arrest in G2 phase cell cycle.
