Domain-specific modeling is a methodological approach or research paradigm concerned with the creation and utilization of models specifically tailored to represent and reason about concepts and processes within a particular problem domain. It investigates techniques for developing formal or semi-formal representations, often involving Domain-Specific Languages (DSLs), that explicitly capture domain knowledge, aiming to improve the precision, efficiency, and automation of system development, analysis, or understanding within that domain compared to general-purpose approaches.
