Action languages for unified modeling language model

Abstract

Methods, mediums and systems are provided to enable a user to program the behaviors of a Unified Modeling Language (UML) model in a graphical programming or modeling environment, such as block diagram programming environment. The UML model is exported into a text-based format, which is subsequently imported into the graphical programming or modeling environment. The graphical programming or modeling environment represents the UML model using functional blocks so that the user can program the behaviors of the UML model. The graphical programming or modeling environment also enables the user to simulate or execute the UML model to determine the behaviors of the UML model

UML is often used for modeling object-oriented programs. UML includes a standardized modeling notation that may be used to create an abstract representation (“UML m...

AI Technical Summary

Benefits of technology

[0012]The graphical model may include extensive textual aspects that can be declarative as well as imperative in nature. In addition, the graphical model may include dynamically typed and statically typed aspects. The graphical action language of the present invention enables a user to graphically program the methods or behaviors of a UML model or components in the UML model so that the UML model can be easily converted to executable code.

Problems solved by technology

UML does not define a formal and precise-enough semantic to allow a user to automatically build an executable model.

Though the behavior of the system can be modeled by statecharts, which is an imperative and untimed language based on state transition diagrams, it is difficult to use statecharts to capture all behavioral aspects of a system.

Unfortunately, UML model designers are generally software architects who construct the UML model at an abstract level and are not always skilled in programming languages and coding.

These languages are well-suited for specifying the finer details of sequences of computations, but are poorly suited for implementing extensive applications such as business software applications.

Developing applications with imperative programming languages is tedious and error prone.

These limitations of imperative programming languages are reflected in the development time and expense and defects found in present day software.

The problems are compounded for real-time computation-intensive systems.

The need for using text-based imperative programming languages to write methods for UML models makes it difficult to employ UML for the design of mission critical functions in real-world applications, such as medical, aerospace or automobile applications.
