When customers present requirements using nouns, the appropriate analysis model to use is the Entity-Relationship Diagram (ERD), as nouns typically represent the entities within a system. The ERD will help in defining and visualizing the entities and their attributes, as well as the relationships between them.
The student is asking which analysis model to use when customers present their requirements using nouns. When requirements are expressed using nouns, these often represent the entities and their attributes within the system being designed. Therefore, the suitable analysis model for this scenario would be Entity-Relationship Diagram (ERD). This means the correct answer is A. Entities of their attributes (ERD). An ERD is useful for modeling databases and depicting the structure of data, including entities and the relationships between them. It is an essential part of the database design process and can help in understanding the data requirements of a system.
For example, if a customer describes a system with nouns like 'customer', 'order', and 'product', these can be seen as entities in an ERD where 'customer' can have attributes such as customer ID and name, 'order' could include an order ID and date, and 'product' might have a product ID and description.
