Quizplus · Accepted Answer

The data access layer classes should contain SQL statements that facilitate the retrieval, insertion, updating, and deletion of data from the underlying database. They should not process business rules or display data fields as these functions belong to the business logic and presentation layers respectively. The input data can be accepted by the data access layer, but it should not have the responsibility of validating or processing this data.
