What are the key differences between an information model and a data model, and how do they impact the overall design and structure of a system?

An information model focuses on the organization and relationships of data within a system, while a data model specifically defines the structure and format of the data itself. The information model guides how data is stored and accessed, while the data model dictates the specific attributes and relationships of the data. These models impact the overall design and structure of a system by ensuring data consistency, accuracy, and efficiency in data management and retrieval.
