There are several advantages for horizontal aggregation.
1)Horizontal aggregation represent a template to generate SQL code fro m a data min ing tool. This SQL
code reduces manual work in the data preparation phase in data min ing related pro ject.
2)It automatically generated code, which is more efficient than end user written SQL code.
Thus datasets for the data min ing projects can be created in less time .
3)The data sets can be created entirely inside the DBMS K-means clustering algorithms are used to cluster the
attribute, that attribute is the result of horizontal aggregation.
