Date's Twelve Rules for Distributed Database Systems - Operating System Independence

Date's Twelve Rules for Distributed Database Systems - Operating System independence / DDBS should support OS independence

Be able to run the same DDBMS on different operating system platforms.

This is applicable for a database spread over multiple servers. The transaction management system should be able to handle a single transaction where data are part of multiple different servers running on different platforms.

Figure 1

Observe from the above diagram that the server at different locations run on different operating systems. If a database is spread over these different servers, the DDBMS must be able to handle all the parts of the database in a way irrespective of Operating systems.

In this example, the University database partitions at multiple locations should be accessible by a DDBMS without any OS related issues.
