ABSTRACT:
In a distributed data base system, different parts of the data base are handled by each of a number of interconnected processors. The different data base parts contain a number of data entities. There are provided for each of such data entities global information relating to the processor in which the data entity is located, and local information relating to the location of the data entity in the own processor. The global information is located in each processor in the system in the form of global information common to and specific for each set of data entities. More particularly, the sets of data entities comprise distribution entities each of which includes information relating to a number of instances of a certain type of data entity located in a certain processor, and information by which the address to this processor can be found.
