Our scheme is a multidimensional order preserving extension of (one-dimensional) linear hashing with partial expansions and thus overcomes these disadvantages. ... For uniform distribution our scheme performs better than its competitors which is underligned by experimental runs with an implementation of our scheme. ... This paper is organized as follows. In section 2 we give a brief description of linear hashing with partial expansions and suggest an order preserving variant. ...doi:10.1007/3-540-17187-8_38 fatcat:6bnr652lpvbthamx6hnirz6rgm

In this paper we complete the analysis done by Ramakrishna and Mukhopadhyay for a data node in the bounded disorder (BD) file organization of Litwin and I.omet. by introducing the B-tree index into the ... Thus, we are able to compare a BD file with other file organizations. ...doi:10.1016/s0304-3975(96)00061-8 fatcat:zgtczsooznc4dfjofkdbfq2ktm
Linear hashing with partial expansions and linear hashing with priority splitting are two variations with improved space and time performance. ... Here, we propose a new structure, which is termed linear hashing with partial expansions and priority splitting. ... Papadimos for their valuable help during the experimentation.

In this paper, we study two new dynamic hashing schemes for primary key retrieval. The schemes are related to those of Scholl, Litwin and Larson. ... Alternatively, an initial loading of the file can be achieved by starting off with g1 d empty home pages, for a suitable d. sp is set to 0. ...
