Ub-Tree Indexing For Semantic Query Optimization Of Range Queries

S. Housseno, A. Simonet, M. Simonet
2009 Zenodo  
This paper presents an indexing method based on UB-trees and a static analysis of the constraints associated to the views of the database and to any constraint expressed on attributes.  ...  The search space corresponding to a range query is restricted to a subset of the blocks of the partition.  ...  The need to index on many attributes and the emergence of multi-dimensional applications motivate the adaptation of single-attribute indexing data structures in these contexts.  ...

On contextual ranking queries in databases

Chengkai Li
2013 Information Systems  
We analytically investigate the advantages and drawbacks of these methods, according to a preliminary cost model.  ...  This method can efficiently identify a small number of candidate tuples, thus achieves lower cost than alternative methods.  ...  We also compare with alternative methods based on single-attribute constraints using histogram, Btree, multi-dimensional index, and bitmap index on single attributes.  ...

1972 Journal of Spacecraft and Rockets  
The application of this simple iterative technique to a multi- layer insulative TPS with air gaps, two or more constraints, however, can be quite tedious and time-consuming.  ...  It can be shown that if the W, are sufficiently large in magnitude, minimization of Eq. (1) subject to the constraints of Eq. (2) is equivalent to the minimization of the unconstrained performance index  ...
