Jul 2, 2019 · Normalization is a technique for organizing data in a database. It is important that a database is normalized to minimize redundancy (duplicate data) and to ensure only related data is stored in each table. It also prevents any issues stemming from database modifications such as insertions, deletions, and updates. The formula is: Normalized value = (X - Xmin) / (Xmax - Xmin) Where X is the original data point, X min is the minimum value in the dataset, and X max is the maximum value in the dataset. By applying this formula to each data point, you can normalize the entire dataset between 0 and 1.

Five normal forms. 1: All occurrences of an entity must contain the same number of attributes. No lists, no repeated attributes. 2: All non-key fields must be a function of the key. 3: All non-key fields must not be a function of other non-key fields. 4: A row must not contain two or more independent multi-valued facts about an entity. Here are the steps to use the normalization formula on a data set: 1. Calculate the range of the data set. To find the range of a data set, find the maximum and minimum values in the data set, then subtract the minimum from the maximum. Arranging your data set in order from smallest to largest can help you find these values easily.Normalization. It is the process of rescaling the values between [0, 1]. Why normalization?
