Tan,Steinbech,Kumar book says-:

A data matrix is a variation of record data, but because it consists of numeric attributes,standard matrix operation can be applied to transform and manipulate the data. Therefore,the data matrix is the standard data format for most statistical data.

I am not understanding why can we apply standard matrix operations to data matrix? What is the logic behind this?
