Question

Multidimensional analysis and descriptive mining of complex data objects

Answer 1

Explanation:

Multidimensional Analysis and Descriptive Mining of Complex Data Objects. Aggregation and approximation should be considered another important means of generalization, which is especially useful for generalizing attributes with large sets of values, complex structure and spatial or multimedia data.

Answer 2

Multidimensional analysis and descriptive mining of complex data objects  are as follows:

• The analysis of dimension objects which are organised in meaningful hierarchies refers to multidimensional analysis. Users are allowed to observe data from different viewpoints.
• The descriptive analysis is used to provide the latest information on recent or past events. It helps in case of describing and summarizing in a meaningful manner.
