In one tier application the UI/Server(business
logic)/Database resides on one node.
The most basic type of client-server architecture employs
only two types of nodes: clients and servers. This type of
architecture is sometimes referred to as two-tier.
The 3-Tier architecture has the following three tiers.
1. Presentation Tier
2. Logic Tier / Business Logic Tier / Transaction Tier
3. Data Tier
Where N-Tier Architecture contains each modules resides in
different node, which are as follows
1. Presentation GUI.
(HTML, Windows Forms etc.)
2. Presentation Logic Tier.
- The Web(VB Script,VB.Net,Java Script etc.)
- Proxy Tier(SOAP,COM,DCOM etc.)
- Client interface
3. Business Tier.
(Business Objects and Rules)
