Multidimensional order preserving linear hashing with partial expansions, the retrieval performance either suffers from a superlinearly growing directory or from an uneven distribution of the records over the pages of a file even for uniform record distribution. Our scheme is a multidimensional order preserving extension of (one-dimensional) linear hashing with partial e

Split-freedom and MVD-intersection: A new characterization of multivalued dependencies having confl]. Their desirable properties motivate the problem of testing a set M of MVDs for the existence of a conflict-free cover. In [GT1] Goodman and Tay have proposed an approach based on the possible equivalence of M to a single (acyclic) join dependency (JD). We remark that their characterization does n

Query processing in incomplete logical databases, ("value not known") represented by axioms of a First Order Theory T. and (b) the data dependencies that are known to be satisfied in the real world. For a given set of dependencies (functional and inclusion dependencies), a chase process transforms in two steps ("forward" and "backward" chase) type
