A data dictionary is a persistent repository of data that is relevant to your model. It lets you store design data, which defines parameters and signals, and it lets you include data that defines the behavior of the model.

In the context of Model-Based Design, Simulink^® users often find themselves working in teams where each team member is working on a different part of the system. Data management between these components becomes crucial for efficient team collaboration. This video walks you through six most common use cases for data management, and explores different ways in which a data dictionary can be used to address these situations.
