ABSTRACT:
The invention relates to a method and system for configuring a database 110, in particular by splitting data objects. This splitting process is frequently termed FRAGMENTATION in database technology. The invention furthermore relates to a method and system for distributing data objects in a database 110. This process is frequently termed ALLOCATION in database technology. Configuration of the database 110 is controlled by the information as to which processes 101, 102, 103 access the data objects of the database 110 in what way and to what extent. In particular, the configuration of distributed databases is controlled by the information as to which processes 101, 102, 103 read from and write to which attributes of the relations, at what frequency. Account is also taken of the locations at which the processes 101, 102, 103 are running. The database 110 can be configured both on initial startup and dynamically during database 110 operation, in order to respond to changed user behavior for instance.
