29. The semantic relational database of claim 12 wherein said phrase registry data store of definitions refers to a stored data item by a multipart key, the multipart key comprised of at least two parts, including an Item ID representing the data item within its registered database system and a Timestamp that is a date-time value used to track and discriminate upgrades and edits of a value of the data item identified by the Item Number.
12. A semantic relational database system, comprising: a phrase registry data store of definitions recorded in a computer readable medium and recording phrase definitions that include word phrase definitions, wherein the word phrase definitions include data entity type phrase definitions and relationship type phrase definitions; a sub-sentence data structure recorded in the computer readable medium and recording at least four sub-sentences, wherein at least three of the at least four sub-sentences are each at least composed of one of the phrase definitions and a syntax type specifying a role of that sub-sentence's phrase definition in a relationship defined by those three sub-sentences, and a fourth sub-sentence of the at least four sub-sentences is at least composed of a phrase definition and an identification of one of the three-sub-sentences to be modified by the fourth sub-sentence's phrase definition; at least two data handlers, including a sentence data handler and a word phrase data handler; and an index and retrieval system receiving at least one query phrase definition from a user and processing the query phrase definition by employing the sentence data handler, contingent on the query phrase definition matching one or more of the phrase definitions of which the at least four sentences are composed, to retrieve a sentence composed of the at least four sub-sentences and syntactically traverse the at least four sub-sentences into an ordered representation of a modified relationship specified by the syntax type of each of the at least three sub-sentences and the modifier target identification of the fourth sub-sentence's phrase definition, and by employing the word phrase data handler to report to the user data entities of the sentences in an order determined by the ordered representation.
