Your company has a customer service application where the client software runs on the customer service representatives' computers and connects to a database that resides on a central server. What type of application architecture does this scenario best describe?
In a two-tier architecture, the client application constitutes the first tier, directly interacting with the database or server as the second tier. This setup manages user interfaces and application logic on the client’s side, while the database system is stored on the server side. The absence of an intermediate layer between the client and the server is why it is named a two-tier architecture. A three-tier architecture would include another separate layer, typically the business logic, which is not mentioned in the scenario.
