Multidimensional data modeling for complex data
free download

The combination of dimensions values that characterize the facts of a fact set is not a key for thevalues, in the sense that several facts may be characterized by the same combination of dimension values.3.2 Handling Time We proceed to build temporal support into the model

Fast similarity search in the presence of noise, scaling, and translation in time series databases
free download

structure was proposed for fast similarity searches over time-series databases, assuming that scan each sequence from beginning to end, extracting and normalizing the !-dimension point correspondingThe index structure should be capable of handling dimensions in this range

Spatial SQL: A query and presentation language
free download

In the context of spatial data handling, a query language is seen as being broader than only a solution for the retrieval of data.These specifica- tions are dimension independent and, therefore, apply to any two objects of arbitrary dimensions. Fig. 2 shows prototypical
