With that in mind, here are the stages of the data normalization process: 1. Unnormalized Form (UNF) The first stage is typically unnormalized data. When data is in an unnormalized form (UNF), it doesn’t meet any requirements for database normalization within the context of a relational model. 2.

“Normalizing” a vector most often means dividing by a norm of the vector. It also often refers to rescaling by the minimum and range of the vector, to make …457. If you want to normalize your data, you can do so as you suggest and simply calculate the following: zi = xi − min(x) max(x) − min(x) z i = x i − min ( x) max ( x) − min ( x) where x = (x1,...,xn) x = ( x 1,..., x n) and zi z i is now your ith i t h normalized data.
