Basic norm of the essential attributes features such as energy as classification, has evaded the multimode and difference of things of society and form well
Property, the apparent classification in data environment is realized, has effectively contained a certain range of ambiguity of data definition.
Specifically, can be illustrated by multistratum classification.All social data can be by several in this taxonomic hierarchies
The classification of layer is defined.First in the first layer of data classification, if all social data are divided into according to its essential attribute
Dry type (such as people, society, nature) when classifying to a certain data, should find its positioning in this layer, so first
It is finely divided in the type, can be divided into if the society of the second layer according to division of labor difference of the different data in society again afterwards
(government, city, enterprise etc.), the government of third layer can be classified according to different institutions are adhered to separately and (be divided into party, political affairs, army etc.) again.
If a data only can find positioning by the classification of " society+government+party ", its addressing be exactly it is one-dimensional, if one
A data are " people ", " society ", and positioning can be found in " nature " three essential attributes or can only be looked in society classifies
It arrives, but " government " in the second layer, " city ", " enterprise " are defined, then it can be carried out three-dimensional categorisation, form three

Data are isolated out in itself, are generated since inherently using main body with things reciprocation occurs in application process for data
's.After things is improved with the contextual definition between application, then classified to data, be not in information island.
Such as an automobile, classify according to affiliated people, can by " affiliated people's (identification card number)+identification of the vehicle " mode into
Row divides, and a part of vehicle can be demarcated in a manner that this is one-dimensional, this side can not be then used when vehicle belongs to government, unit
Formula.So then increase new dimension " division of labor in society " to be demarcated, such as " society+government+Ministry of Communications (vehicle responsible institution)+
Identification of the vehicle " and can be by the way that " society+processing and manufacturing+identification of the vehicle (wraps in identifier for the vehicle do not sold
Information containing manufacturing enterprise) ", and so on, vehicles all present on society can be classified, and can be by various
Mode carries out data query.
For another example, hospital is gone to measure body temperature.Classify according to affiliated people, " affiliated people's (identification card number)+time+body temperature " can be passed through
It is divided, and can be divided by " society+hospital+patient+time+body temperature ".By the mode classification of multidimensional, can protect
Positioning can be found in taxonomic hierarchies by demonstrate,proving all social data, effectively avoid the generation of information island.
