VisDB: Database exploration using Multidimensional Visualization

Typical difficulties faced with large databases:
Obtain weighting factors (Wj, j Є 1, ……, #sp) as per order of importance from users.
Linear transformation of the range [dmax,dmin] for each predicate
1. Weighted arithmetic mean for ‘AND’ – connected condition part.
Relevance factor is inverse of distance value
In this we generate a separate window for each selection predicate of the query.
Negative distances to left,
Positive distances to right,
For other dimension
Negative distances to bottom,
Positive ones to top
