Answer: (b).To model the data aspect of an information system Explanation:The Entity--Relationship Modeling is a widely-known technique used to model the data aspect of an information system. It provides a way to represent the relationships between entities, such as objects, data elements, and their attributes, in a structured and organized manner. This helps to capture the data requirements and specifications of an information system, and provides a clear understanding of the data structure and relationships. The resulting representation can be used as a basis for database design and implementation.
