Subclassification is the process of dividing a broader category into smaller, more specific groups. This method helps in organizing information, making it easier to study and understand. For example, in biology, the classification of living organisms starts with broad categories like Kingdom and Phylum, which are then subdivided into more specific groups such as Class and Order. In various fields, subclassification aids in detailed analysis and research. In library science, books are subclassified by genres or subjects, allowing readers to find materials that match their interests quickly. Similarly, in data management, subclassification helps in sorting and retrieving information efficiently.
