How do we display hierarchical relationship in data?
Adjacency List is a design method for implementing hierarchical data. It's achieved by storing the ID of the related record on the desired record. You add one column to your table, and set it as a foreign key to the same table's primary key.
What are the graphical methods to visualize hierarchical data?
Definition: Treemaps are visualizations for hierarchical data. They are made of a series of nested rectangles of sizes proportional to the corresponding data value. A large rectangle represents a branch of a data tree, and it is subdivided into smaller rectangles that represent the size of each node within that branch.
How do you show hierarchy in SQL?
Use hierarchyid as a data type to create tables with a hierarchical structure, or to describe the hierarchical structure of data that is stored in another location. Use the hierarchyid functions in Transact-SQL to query and manage hierarchical data.
