| Description | A group of objects that form a tree structure in which parent concepts on higher levels branch out into child concepts on lower levels. For example: Balanced hierarchy: Concept types within a level are logically consistent. All branches have the same depth and no levels are skipped. For example a calendar hierarchy with years, quarters, months, weeks and days as levels. Unbalanced hierarchy: Levels are not consistent across branches. Branches can have different depths. For example an organization chart with managers and employees where not all the employees reporting to the same manager have functionally equivalent positions. Ragged hierarchy: Concept types within a level are logically consistent. Branches can have different depths and levels can be skipped on some branches. For example an administrative division hierarchy with country, state, county, and city. |
