By organizing and arranging data according to hierarchical structure, the relationship between data is clearly visible and easy to find, manage and understand. The following is a detailed definition and explanation of tree classification.
Definition of 1. tree classification:
Tree classification is a method of data organization and visualization, which is used to stratify and organize data according to hierarchical structure, so as to better understand the relationship and hierarchical structure between data. It usually represents data in the form of a tree diagram, in which the trunk represents the main category or hierarchy, the branches represent sub-categories or hierarchies, and the leaf nodes represent specific data items.
2. The characteristics of tree classification:
Hierarchical: tree classification arranges data according to hierarchical structure, and decreases step by step from root node to leaf node. Each level represents a different level or category, which makes the organization and classification of data clearer.
Hierarchical classification: each node can contain multiple child nodes, thus realizing hierarchical classification. This means that data can be subdivided into different subcategories, making the classification of data more detailed.
Visual expression: tree classification usually represents data in the form of tree diagram, and the relationship between data is clear at a glance. This visual expression is convenient for users to understand and browse data.
Search and find: Tree classification helps users quickly find and access the data they need. Users can find the target data item by navigating down the branch.
3. Application fields of tree classification:
Tree classification is widely used in various fields, including but not limited to the following aspects:
Computer Science: In computer science, tree classification is often used in data structure and algorithm design. For example, binary tree and multi-branch tree are common data structures, which are used to organize and process data.
Information management: In the field of information management, tree classification is used to organize and manage files and documents. The file system of the operating system and the navigation menu of the website all adopt a tree structure.
Biology: biologists use tree classification to organize the classification information of biological species in order to study and understand biodiversity.
Library science: the catalogue and classification system in library science usually adopts tree classification to facilitate readers to find books and materials.
Data analysis: In data analysis and data visualization, tree classification helps to organize and present complex data relationships for in-depth analysis and understanding.
