Abstract:
Partitioning and replication of data are very important concepts in logical database design of both centralized and distributed databases. It is very important that the relationships among the vertical and/or horizontal partitions of a relation and the information about data replication be explicitly modeled and dynamically maintained so that their integrity and consistency can be automatically enforced by a DBMS or a distributed DBMS. In this paper, we present an extended generalization concept and show how it can be used to explicitly model various types of data partitions with or without replication. Storage operation rules for these partition types are defined for integrity control purposes and rules for modifying the schema at run time, when partitions are dynamically created or modified, are also presented. Integrity control can be enforced by following the modified model and constraints of these partitions.
