Pivoting

Definition

Pivoting refers to the process of reorganizing or restructuring data to provide a different perspective or summary of the information. This technique is particularly useful in data analysis, allowing users to transform rows into columns and vice versa, which helps in uncovering insights and making data more understandable.
