The second normal form is defined by experts as “eliminating repeating groups,” and “eliminating any partial dependencies among database relations.” If that sounds confusing, you can also think about 2NF as an attempt to “reduce redundant data being stored in memory.” For example, if the...
Normalization is a process of structuring or organizing the data in such a way that we can minimize the redundancy(data which are repeated), insertion, deletion and update anomalies. There are many types of normalization methods. 1NF (First Normal Form) 2NF (Second Normal Form) ...

First Normal form is the first step of normalization. In this tutorial we will have an example to explain how you can update you table to follow the First Normal Form or 1NF. This is the beginning of Database Normalization process.
First Normal Form (1NF): You make sure there are no hidden values in any columns and only one value in each field. Second Normal Form (2NF): You make sure all non-key columns depend on the primary key. Third Normal Form (3NF): Non-primary key columns don’t depend on other non-...
