14. The method according to claim 1 , wherein a structure in the structure dictionary takes a form of a word built using an alphabet of symbols taking a form of constants corresponding to at least one of alpha-numeric strings and characters, and variables corresponding to at least one generic data type, the word being built using formation rules of a formal language, the method of building the structure sub-collection of values matching said word comprising: storing portions of values corresponding to the same symbol in the same symbol sub-collection, the values matching the word, the portions matching the symbol while parsing the values along the structure of the word; and storing the structure sub-collection in a form of the symbol sub-collections corresponding to all particular symbols from which the word is formed using the formation rules.

The method according to claim 14 , wherein the sub-collection of values matching a word in a structure dictionary is retrievable from the corresponding structure sub-collection in a form of the collection of non-null values, the non-null values being in unique correspondence with the values, said non-null values being formed along with data types of attributes that the values correspond to, the non-null values being formed from the portions of values corresponding to symbols from which the word is formed using the formation rules.
