Data classification is the process of organizing data into categories based on specific criteria. This helps in managing, storing, and retrieving data efficiently. By classifying data, organizations can ensure that sensitive information is protected and that relevant data is easily accessible for analysis and decision-making. There are various methods of data classification, including supervised learning and unsupervised learning in machine learning. These methods help in identifying patterns and relationships within the data. Proper data classification is essential for compliance with regulations and for enhancing data security, making it a critical aspect of data management strategies.
