The Role of the Data Dictionary in the Model-Based Development Process

Data dictionaries in embedded automotive applications are used for storing data elements and definitions supporting functional and software development. A robust model-based development process should be driven by a data dictionary that can interact with tools supporting a model-based environment and provide a linkage between different stages of the development process. A data dictionary could significantly increase automation of the modeling, validation and autocoding stages of the process. Using a data dictionary in model-based development implies additional requirements to the Dictionary compared to the traditional non-model development process.

This paper describes the usage of a data dictionary in different stages of the model-based development process. It specifies the set of major requirements for the data dictionary and offers the possible implementation of these requirements based on a data dictionary developed by Delphi.
