A tree structure, tree diagram, or tree model is a way of representing the hierarchical nature of a structure in a graphical form. It is named a "tree structure" because the classic representation resembles a tree, although the chart is generally upside down compared to a biological tree, with the "stem" at the top and the "leaves" at the ...
Thegn. Ivory seal of Godwin, an unknown thegn – first half of eleventh century, British Museum. In later Anglo-Saxon England, a thegn (pronounced / θeɪn /; Old English: þeġn) or thane[1] (or thayn in Shakespearean English) was an aristocrat who owned substantial land in one or more counties. Thanes ranked at the third level in lay society ...
In information visualization and computing, treemapping is a method for displaying hierarchical data using nested figures, usually rectangles. Treemaps display hierarchical (tree-structured) data as a set of nested rectangles. Each branch of the tree is given a rectangle, which is then tiled with smaller rectangles representing sub-branches.
A structure chart (SC) in software engineering and organizational theory is a chart which shows the breakdown of a system to its lowest manageable levels. [2] They are used in structured programming to arrange program modules into a tree. Each module is represented by a box, which contains the module's name.
Imperial, royal, noble,gentry and chivalric ranks in Europe. Thane (/ ˈθeɪn /; Scottish Gaelic: taidhn) [1] was the title given to a local royal official in medieval eastern Scotland, equivalent in rank to the son of an earl, [2] who was at the head of an administrative and socio-economic unit known as a thanedom or thanage.
Process decision program chart. A useful way of planning is to break down tasks into a hierarchy, using a tree diagram. The process decision program chart (PDPC) extends the tree diagram a couple of levels to identify risks and countermeasures for the bottom level tasks. Different shaped boxes are used to highlight risks and identify possible ...
Order of operations. In mathematics and computer programming, the order of operations is a collection of rules that reflect conventions about which operations to perform first in order to evaluate a given mathematical expression. These rules are formalized with a ranking of the operations. The rank of an operation is called its precedence, and ...
In computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes. Each node in the tree can be connected to many children (depending on the type of tree), but must be connected to exactly one parent, [1] except for the root node, which has no parent (i.e., the root node ...
