摘要： According to a first aspect of the present invention there is provided a method of operating a distributed database comprising a plurality of database nodes each storing a plurality of data objects. The method comprises, when executing a database transaction that requires data operations be performed on a plurality of data objects that are distributed between two or more of the database nodes, grouping the data objects that are involved in the database transaction at one of the plurality of database nodes.

摘要： A real time database system configured to store database content with a plurality of data sets, the database content being partitioned in different partitions. The system comprises a plurality of master databases, each master database containing a partition of the database content, each partition being provided on a different physical storage unit and at least one replica database, each replica database containing subpartitions of the partitions stored in master databases. The system further comprises at least one distributor configured to route a request for a data set to the master database, where the data set to which the request refers to, is provided, and divide each partition into several subpartitions. Additionally, the system comprises at least one replicator, configured to generate a replica of each subpartition, and configured to store each replica on a replica database.
