Question

Quizplus · Accepted Answer

The most common n-tier architecture involves three tiers: presentation tier (UI), application tier (logic) and data tier (database). These tiers help to separate concerns and improve scalability, maintainability, and security of an application. Two-tier architecture is not n-tier and implies a lack of separation between UI and database layers. Four or five tiers are not as common and can be more complex to implement and maintain.
