Abstract
Dynamic (virtual) hashing methods (DVH) manage very large files by the means of an index which is, at least partially, stored in the core. Usually this index is a binary tree (b-t), and different implementations of DVH are based on the representations of the b-t using pointers or links to descendants or leaves. We show that it is also possible to represent a p-ary tree (p-t), and thus a b-t, with a word of a certain language, and to use this pointerless representation to perform all the operations needed by a DVH generalized to p-t's. We present this language, we study its operative properties, and we indicate how to perform the operations of search, insertion,... We compare our representation to the most usual ones, and we analyze the complexity of some algorithms in relation with this representation.
