Database Compression: A Performance Enhancement Tool - Ray, Haritsa, Seshadri (1995) (4 citations) (Correct)
....Sev83, Cor85, Bas85, Reg81] These studies evaluate the various types of compression techniques from a storage perspective but do not consider their suitability for database query processing. Considerable work has been done in the field of compression of scientific and statistical databases (e.g. [Bat83, EOS81, McC82, BH83, LST83]) However, the nature of data and the types of operations in these databases differ significantly from those in commercial databases, which is our target domain. In the last few years, a couple of studies [Gra93, BW94] have considered issues similar to those considered in this paper. While ....

Adaptive Selectivity Estimation Using Query Feedback - Chen, Roussopoulos (1993) (44 citations) (Correct)
....any of the known model functions, any attempt to approximate the distribution by this method will be in vain. Contributions to research of parametric methods can be found in [S 79, SB83, Fed84, Chr83b, Chr83a] Curve Fitting In order to overcome the inflexibility of the parametric method, LST83] and [SLRD93] used a general polynomial function and applied the criterion of least squareerror to approximate attribute value distribution. First, the relation is exhaustively scanned, and the number of occurrences of each attribute value is counted. These numbers are then used to compute the ....
....the updates exceed a threshold) The rest of this paper is organized as follows: Section 2 describes the adaptive selectivity estimator in detail. Section 3 presents some of our experimental results. Finally, conclusions are given in Section 4. the Legendre polynomials are used as the basis in [LST83] 2 Adaptive Selectivity Estimation In this section, we describe the implementation of an Adaptive Selectivity Estimator (ASE) At the heart of our approach is a technique called recursive least square error (RLSE) which is adopted to adjust the approximating distribution according to ....
