Difference Between Two-Tier And Three-Tier database architecture
1. Two-Tier Database Architecture –
In two-tier, the application logic is either buried inside the User Interface on the client or within the database on the server (or both). With two-tier client/server architectures, the user system interface is usually located in the user’s desktop environment and the database management services are usually in a server that is a more powerful machine that services many clients.
2. Three-Tier Database Architecture –
In three-tier, the application logic or process lives in the middle-tier, it is separated from the data and the user interface. Three-tier systems are more scalable, robust and flexible. In addition, they can integrate data from multiple sources. In the three-tier architecture, a middle tier was added between the user system interface client environment and the database management server environment. There are a variety of ways of implementing this middle tier, such as transaction processing monitors, message servers, or application servers.
Difference Between Two-Tier And Three-Tier Database Architecture
||Two-Tier Database Architecture
||Three-Tier Database Architecture
||It is a Client-Server Architecture.
||It is a Web-based application.
||In two-tier, the application logic is either buried inside the user interface on the client or within the database on the server (or both).
||In three-tier, the application logic or process resides in the middle-tier, it is separated from the data and the user interface.
||Two-tier architecture consists of two layers : Client Tier and Database (Data Tier).
||Three-tier architecture consists of three layers : Client Layer, Business Layer and Data Layer.
||It is easy to build and maintain.
||It is complex to build and maintain.
||Two-tier architecture runs slower.
||Three-tier architecture runs faster.
||It is less secured as client can communicate with database directly.
||It is secured as client is not allowed to communicate with database directly.
||It results in performance loss whenever the users increase rapidly.
||It results in performance loss whenever the system is run on Internet but gives more performance than two-tier architecture.
||Example – Contact Management System created using MS-Access or Railway Reservation System, etc.
||Example – Designing registration form which contains text box, label, button or a large website on the Internet, etc.
