Data classification is a process of organizing and categorizing data into different groups or classes based on certain criteria. This process helps in identifying and understanding the characteristics of data to make it easier to manage, retrieve, and analyze. Classification algorithms are commonly used in data mining and machine learning to automatically classify or categorize data based on patterns and relationships within the data. These algorithms can be applied to various types of data, such as text, images, and numerical data, to extract meaningful insights and make predictions. Data classification is an essential part of data management and information security, as it helps in protecting sensitive information by assigning appropriate security levels and access controls to different data classes. It also plays a crucial role in organizing and structuring data for efficient data retrieval and analysis.
