What is 2-Tier architecture?

by

The 2-Tier architecture is the same as basic client-server. In the two-tier architecture, applications on the client end can directly communicate with the database at the server side.

In a 2-tier architecture for a database management system (DBMS), there are two layers or tiers involved: the client tier and the server tier.

  1. Client Tier: This is where the user interface resides. It interacts directly with the end-user and sends requests to the server tier for processing. The client tier is responsible for presenting data to users and collecting user inputs.
  2. Server Tier: This tier hosts the database management system itself. It is responsible for handling data storage, retrieval, and processing. The server tier receives requests from the client tier, executes them, and sends back the results.

In essence, the 2-tier architecture is characterized by having the client-side application responsible for presentation logic and user interaction, while the server-side application manages data storage and processing.
