52. The method of claim 41 , wherein the plurality of data cells include a plurality of collective data cells, and wherein a collective data cell characterised as one of enumeration comprises a plurality of properties, wherein each property comprises a sequence of bits such that certainty of possession of a property by the attribute instance corresponding to said collective data cell can be determined by a comparison of said bits in like sequence order for one or more respective properties.
41. A method of data storage and/or retrieval implemented on one or more digital data processing systems, comprising: providing storage media comprising a plurality of data tunnels, one or more of said plurality of data tunnels having a plurality of data cells, wherein the plurality of data tunnels include a plurality of entity type data tunnels for each of a plurality of entity types and a plurality of attribute data tunnels for each of a plurality of attributes wherein a number of data tunnels for each attribute is fixed for a given attribute, wherein each of the data cells contain data associated with a respective instance of an attribute for a respective and distinct instance of an entity type, wherein each of the data cells of the plurality of attribute data tunnels has data for which a respective operator evaluates to a boolean result indicating either the likely possibility or the impossibility of the attribute instance corresponding to said data cell being characterised by said operator for a given set of one or more operands, and accessing, with a storage engine that is in communications coupling with the storage media, one or more of the plurality of data tunnels based on one or more of said operators and a given set of one or more operands.
