Final answer:
Data Courier classifies category dependencies based on relationships between data categories using a graph-based approach.
Step-by-step explanation:
Data Courier classifies category dependencies based on the relationships between data categories. It uses a graph-based approach to represent these dependencies. Each category is represented by a node in the graph, and the relationships between categories are represented by edges. For example, if Category A depends on Category B, there would be a directed edge from Category B to Category A. This allows Data Courier to track and manage the dependencies between categories and ensure that data is transferred properly.
