Date's Tweleve Rules for Distributed Database Systems - Network Independence

Date's Tweleve Rules for Distributed Database Systems - Network Independence


The system should not depend on particular network implementations and protocols.

Network Independence rule can be defined in different way as follows;


  • Desirable to be able to support a variety of disparate communication networks also.
  • Network independence: The DDB and its associated DDBMS should be capable of being implemented on any suitable network platform. 

    Note:  At present, this goal means that the DDBMS should be able to run on Windows NT, on Windows 2000, on any variant of Unix, and on Novell Networks. 
  • A distributed database system should be designed to run regardless of the communication protocols and network topology used to interconnect various system nodes.
