Resumen
The article focuses on symbolic modeling. Modeling is a complex activity of abstracting information and knowledge from a particular domain in order to achieve a model containing the essentials from the perspective of the modelers and their given goals. Symbolic modeling is employed in a variety of fields. Examples include task and domain modeling in human-computer interaction, semantic data modeling for database systems, knowledge acquisition and representation in artificial intelligence and object-oriented (OO) modeling in software engineering. At the current state of practice, OO approaches seem to be having a strong impact on software development. Some of the major OO analysis and design methods also led to the definition of the so-called Unified Modeling Language (UML). The availability of such a standardized diagrammatic language may be important for the practice of symbolic modeling. One of the strong aspects of diagrammatic languages such as the UML is their support of visual modeling.
