Answer 1

An object in an information system is a representation of a real-world entity, and it can be a person, a product, or a transaction. Three examples are a customer entity in a CRM system, a product attribute in a database management system, and a user relationship in a social networking platform.

Step-by-step explanation:

An object in an information system can be defined as a representation of a real-world entity, such as a person, a product, or a transaction. Objects are used to store and manipulate data within the information system. Here are three examples:

1. Entity: In a customer relationship management (CRM) system, a customer can be represented as an entity object. This object would contain information about the customer, such as their name, contact details, and purchase history.
2. Attribute: In a database management system, a product can be represented as an object with various attributes. For example, an object representing a product could have attributes such as name, price, quantity, and description.
3. Relationship: In a social networking platform, a relationship between two users can be represented as an object. This object would capture information about the connection between the users, such as their friendship status, messages exchanged, and shared interests.
