Data Mining learning notes Multidimensional Data Model-data cube

The multidimensional data model is a fact-and-dimension-based database model established to meet the needs of users to query and analyze data from multiple perspectives and layers, its basic application is to implement OLAP (Online Analytical Processing ). Each dimension corresponds to one or a group of attributes in the mode, and each unit stores a certain clustering metric value, such as count or sum. Cub

Spatial Data Mining Methods

Spatial Data Mining refers to the process of extracting hidden knowledge and spatial relationships from spatial databases and discovering useful Theories, Methods, and technologies of features and patterns. The process of spatial data mining and knowledge discovery can be roughly divided into the following steps:
