We perform spatial objects clustering when creating levels of the structure. For this purpose we employ a density-based clustering algorithm. The algorithm requires an

Spatial OLAP (SOLAP) refers to the integration of spatial data in multidimensional applications at physical, logical and conceptual level. Using spatial measure as a geographical object, i.e. taking in account its geometric and descriptive attributes, raises problems reg

For complex SBQL views this method is not always applicable because a view can depend on some private server resources (thus it cannot be sent to the client side) or a view is defined by a complex algorithm (t

Samhitha Bydar Shubhashchandra,Sandhya Rao This consistency assumption has been exploited for improving the efficiency of determining whether integrity is satisfied or violated after the update. Based on a notion of violation tolerance, we present and discuss an abstract property which, for any given approach to integrity checking, is an ea
