Question

Quizplus · Accepted Answer

The business tier (also called application tier or logic tier) contains the business logic and calculations of the system. It is responsible for processing and manipulating data, implementing business rules, and performing complex computations. The other two tiers are the presentation tier (responsible for displaying data to the users and handling user input) and the persistence tier (responsible for storing and retrieving data from a database or other data storage system). The validation tier is not a standard tier in a three-tier architecture, and its responsibilities are usually distributed between the presentation and business tiers.
