BA4791. Background: Assume that an organization has 2 database servers and 50 clients.  Assume that the application logic load is distributed across two application servers.  Assume that any request from a client involves one database server and both application servers.  Question: What tier client-server architecture does this setup represent?  If your answer is n-tier architecture, specify the value of n.  2. Background: A okerage firm is considering two alternatives.  The first is to have a special tool developed in C++ that clients will download onto their computers to run.  This tool will communicate with the firm’s server to select the data to be analyzed.  The second alternative will have the C++ program on the firm’s server.  In this alternative, the client will use a web owser to interact with the firm’s server.  Question: 2(a): Identify the type of client (i.e., Thin vs. Fat) each alternative uses.  Question: 2(b): Identify advantages and disadvantages of using thin clients.  3. Question: Identify and iefly describe at least one advantage and one disadvantage of selecting an n-tier architecture over a two-tier architecture.

Please find detailed explanation inline.
Question: What tier client-server architecture does this setup represent?  If your 
answer is n-tier architecture, specify the value of n.
Ans:  
• It’s a 3-tier architecture. Because it has 3 different layers of logic. The 
tier means not count all entities in model. It just defines how model 
differentiated.
      Question: 2(a): Identify the type of client (i.e., Thin vs. Fat) each alternative uses.
Ans:  
• First alternative uses Fat client. Fat client is also known as thick client. 
• Second alternative uses thin client. Thin clients have browser-based 
installation. In this client there is complete processing on server side.
      Question: 2(b): Identify advantages and disadvantages of using thin clients.
Thin clients Advantages:.  
• Thin clients uses when we need to work on less space. Using thick client 
requires lots of space.
