* ''Graphical'' modeling languages use a [[diagramming technique|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 (data modeling language)|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 system]]s.

A large number of modeling languages appear in the literature.
