Does the business layer model processes, such as user authentication and transactions?

1. True

2. False

The correct answer is: True

The business layer in a software architecture model is responsible for implementing the core functionalities that drive the application's business logic. This layer typically handles processes such as user authentication, where it validates user credentials and manages session states, ensuring secure access to the system. Additionally, it is involved in managing transactions, which include creating, reading, updating, and deleting data while ensuring data integrity and consistency. By placing these essential processes within the business layer, the application separates concerns effectively, allowing for a more organized structure and easier maintenance. This separation also enhances security, as the business layer can encapsulate complex logic away from the user interface, reducing the risk of exposing sensitive operations to direct user interactions. Overall, the business layer plays a crucial role in supporting these fundamental processes, making the answer true.
