The hBΠ-tree: A Concurrent and Recoverable Multi-attribute Access Method
نویسندگان
چکیده
We describe a new access method, the hBΠ-tree, an adaptation of the Lomet and Salzberg hB-tree index to the constraints of their Π-tree . The Π-trees, a generalization of the Blink-trees of Lehman and Yao, provide very high concurrency with recovery, hence permitting highly parallel access to data. The hB-tree is a multi-attribute index which is highly insensitive to dimensionality. The combination makes the hBΠ-tree suitable for inclusion in a general purpose database management system supporting multi-attribute and spatial queries.

متن کاملA Comparative Study of Multi-Attribute Continuous Double Auction Mechanisms
Auctions have been as a competitive method of buying and selling valuable or rare items for a long time. Single-sided auctions in which participants negotiate on a single attribute (e.g. price) are very popular. Double auctions and negotiation on multiple attributes create more advantages compared to single-sided and single-attribute auctions. Nonetheless, this adds the complexity of the auctio...
متن کاملA Hybrid Multi-attribute Group Decision Making Method Based on Grey Linguistic 2-tuple
Because of the complexity of decision-making environment, the uncertainty of fuzziness and the uncertainty of grey maybe coexist in the problems of multi-attribute group decision making. In this paper, we study the problems of multi-attribute group decision making with hybrid grey attribute data (the precise values, interval numbers and linguistic fuzzy variables coexist, and each attribute val...
متن کاملMULTI-ATTRIBUTE DECISION MAKING METHOD BASED ON BONFERRONI MEAN OPERATOR and possibility degree OF INTERVAL TYPE-2 TRAPEZOIDAL FUZZY SETS
This paper proposes a new approach based on Bonferroni mean operator and possibility degree to solve fuzzy multi-attribute decision making (FMADM) problems in which the attribute value takes the form of interval type-2 fuzzy numbers. We introduce the concepts of interval possibility mean value and present a new method for calculating the possibility degree of two interval trapezoidal type-2 fuz...
متن کاملSensitivity Analysis of Simple Additive Weighting Method (SAW): The Results of Change in the Weight of One Attribute on the Final Ranking of Alternatives
Most of data in a multi-attribute decision making (MADM) problem are unstable and changeable, then sensitivity analysis after problem solving can effectively contribute to making accurate decisions. This paper provides a new method for sensitivity analysis of MADM problems so that by using it and changing the weights of attributes, one can determine changes in the final results of a decision ma...
