A modeling language is any artificial language that can be used to express information or knowledge or systems in a structure that is defined by a consistent set of rules. The rules are used for interpretation of the meaning of components in the structure. == Overview == A modeling language can be graphical or textual.〔Xiao He (2007). "A metamodel for the notation of graphical modeling languages". In: ''Computer Software and Applications Conference, 2007. COMPSAC 2007 - Vol. 1. 31st Annual International'', Volume 1, Issue , 24–27 July 2007, pp 219-224.〕 * ''Graphical'' modeling languages use a diagram technique with named symbols that represent concepts and lines that connect the symbols and represent relationships and various other graphical notation to represent constraints. * ''Textual'' modeling languages may use standardized keywords accompanied by parameters or natural language terms and phrases to make computer-interpretable expressions. An example of a graphical modeling language and a corresponding textual modeling language is EXPRESS. Not all modeling languages are executable, and for those that are, the use of them doesn't necessarily mean that programmers are no longer required. On the contrary, executable modeling languages are intended to amplify the productivity of skilled programmers, so that they can address more challenging problems, such as parallel computing and distributed systems. A large number of modeling languages appear in the literature. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Modeling language」の詳細全文を読む スポンサード リンク
