relative evaluation or assessment, in a given semantic universe, of the various classes that define generic isotopies.

Generic (broader)-specific (narrower) or whole-part relationships, which are generally indicated in a thesaurus through codes or indentation ( NISO). A graphic arrangement of terms showing genus-species or broader-narrower relationships between the terms.

The relationship of various accounts or entities within a multi-level structure.

a cascaded series of many-to-one relationships

an organization in which each part has a defined relationship with the other parts

a set of classes with relationships

a system that shows relationships between terms from general, broader concepts to more specific categories

a way of arranging subjects to show the relationships between them

a way of organizing information in a "pyramid" - where each step of the pyramid is subordinate to the one above it

A WebDB component that displays data from a self-referencing table or view (at least two columns in the table must share a recursive relationship). A hierarchy can contain up to three levels and displays data such as employees in an organization chart, or the hierarchical relationship between menus in a web site.

The relationship among items. You can drill up or drill down to related items.

An arrangement of terms showing Broader-Narrower relationships between them.

A classification of relationships in which each item except the top one (known as the root) is a specialized form of the item above it. Each item can have one or more items below it in the hierarchy. In the Java class hierarchy, the root is the Object class.

a relationship between modules where one module is the parent or controller of another module. Inheritance (IS-A) relationships between classes and calling/called relationships between functions are examples of hierarchies.

a system of persons ordered by class -middle-class, upper-class

Broader (generic) to narrower (specific) or whole-part relationships, which are generally indicated in a controlled vocabulary through codes or indentation. See also broader term; narrower term.

See class hierarchy.

A structural relationship in which each unit consists of two or more sub units, the latter been similarly divided

A pyramid-shaped grouping of classes in which the topmost class is the superclass of all classes below it.

In COBOL, a set of entries that includes all subordinate entries to the next equal- or higher-level number.

A homogeneous class of concepts with part/whole or genus/species relationships, typically displayed by using the descriptor (preferred term), additional identifying information (such as "place type" in TGN), and indention to represent the relationships.

The successive grouping of closely related organisms into larger and larger groups. Species are grouped into a genus, then genera into a family, families into an order, orders into a class, classes into a phylum, and phyla into a kingdom.

A set of relationships in which each item, except the root, is a subset of the item above it. Reporting relationships such as person-to-person, position-to-position and department-to-department are used when charting your organization in OrgPublisher and OrgBuilder.

In computer science's object-oriented programming, the mapped relationships of sub- and superclasses is known as a hierarchy. This can be visualized as an upside-down tree (or perhaps a pyramid), the top of which is known as the root. The issue is more complicated with languages that support multiple inheritance, where hierarchy can be any directed acyclic graph.

In mathematics, a hierarchy is a preorder, i.e. an ordered set. The term is used to stress a natural hierarchical relation among the elements. In particular, it is the preferred terminology for posets whose elements are classes of objects of increasing complexity.
