Claim 10:
11. A data analytical processing method in a data analytical processing device that analyzes, by an online analytical processing (OLAP) manipulation, an event in a real world which changes in terms of at least one of time and space due to at least one of creation and annihilation and state transition by mapping data which embodies the event onto a multidimensional cube, comprising:
associating pieces of data in a temporal dimension and spatial dimensions embodying temporal and spatial changes due to at least one of the creation and annihilation and the state transition and pieces of data in intrinsic dimensions of a plurality of types dependent on subjects, and pieces of data which are identified by the pieces of data in the temporal dimension, the spatial dimensions, and the intrinsic dimensions and represent properties of the plurality of types dependent on the subjects as the data embodying the event with an identifier of the event for identification of the event as a source of information on the pieces of data, and accumulating and managing the pieces of data in multidimensional cubes which are constructed for the respective subjects in a storage device; and
executing the OLAP manipulation on the multidimensional cubes, where, as the piece of data in the temporal dimension embodying the event that has a period of presence from a start time point to an end time point and takes at least one state during the period of presence,
an external time period representing the period of presence of the event on the basis of an absolute time system having, as an origin, a single time point common to all events including the event and
at least one internal time period each representing a period of state maintenance for transition of the event from a given state to a different state on the basis of a relative time system having, as an origin, a start time point of the external time period.
