Abstract: A data processing system including multiple processors with a hierarchical cache structure comprising multiple levels of cache between the processors and a main memory, wherein at least one page mover is positioned closer to the main memory and is connected to the cache memories of the at least one shared cache level (L2, L3, L4), the main memory and to the multiple processors to move data between the cache memories of the at least one shared cache level, the main memory and the processors. In response to a request from one of the processors, the at least one page mover fetches data of a storage area line-wise from at least one of the following memories: the cache memories and the main memory maintaining multiple processor cache memory access coherency.

Abstract: A method for storing data in a replicated data storage system according to the invention comprises the steps of: partitioning the data into data blocks; and storing multiple replicas of a data block in a machine readable medium.

Abstract: A method of storing and accessing data in a database system is disclosed. The database system comprises at least one primary data source. The database system is associated with at least one adapted data structure that defines the physical data storage structures (e.g., row storage and columnar storage) in which the data are stored. Data is allocated from the at least one primary data source to the at least one adapted data structure in correlation with a database query received. For example, based on the data access patterns (e.g., queries), the physical data storage structures in which the data managed by the database system are to be stored are dynamically determined.
