Question

Quizplus · Accepted Answer

The presentation tier is responsible for handling the user interface and user interaction. Therefore, the data-entry form, which accepts user input, would be located in the presentation tier. The persistence tier is responsible for data storage and retrieval, the business tier contains the application logic, and there is no specific "record" tier in the three-tier structure.
