(Ajinkya and Twisha are class mates at VGSOM. Twisha missed MIS Professor's lecture today as she was ill and hence called Ajinkya to tell him what were taught in the class today.)
Ajinkya : Hey Twisha ! How are you doing now ?
Twisha : Hey Ajinkya ! Im better now, went to BC Roy and the doctor prescribed some medicines. I feel better after taking them. Guess I will be able to come to college from tomorrow.
Ajinkya : Oh thats great ! You missed an interesting MIS lecture today. Remember we had a subject named system architecture in our Btech days. This lecture was regarding the same, except the fact that it was really just an interesting overview and not the boring details that we were taught that whole semester.
Twisha : Oh ! Frankly I just remember the name of the subject and nothing more.
Ajinkya : Yes, I also had the same reaction when I saw the slides. No problems, let me do the honors of reminding you the nuances of the great topic
Twisha : Thanks a lot! As far as I remember, it is a formal description and representation of a system, right ?
Ajinkya : Yeah, almost there. Actually system architecture establishes the basic structure of the system, defining the essential core design features and elements that provide the framework for all that follows.
Twisha : I didn't quite get you, can you try explaining in simpler terms ?
Ajinkya : Sure ! Its like when we consider a system, it might be composed of a server, a client and a communication channel, right ? So system architecture refers to the way multitudes of such servers, clients and communication channel are arranged.
Twisha : Got it ! So fundamentally, its is a reference model to organize the various elements of a system into complementary and consistent views. Can it be of various types then ? Because systems can be of varied types and complexities !!
Ajinkya : I was coming to that. So depending on the complexity and no of entities involved, it can be 2,3 or n tier architecture. Let me show you with these two diagrams :
This is two tier architecture since it has one user requesting for services and a database where all the data resides along with a application server to process the data request and send it back to the client.
Twisha : Oh perfect ! I think I got it, so a three tier architecture will look like this ?

Ajinkya : Right ! Perfect, since the application logic resides in a different layer. Similarly, n tier architecture would follow in design.
Twisha : Hmm, great ! I guess I will try reading the book as well. Will ask you if I don't get anything from there.
Ajinkya : Sure, anytime ! And since we will be continuing the same topic in the next lecture, you can ask your queries in class too. I gotta go now, didn't have my dinner yet.
Twisha : Ok, sure ! See you in class tomorrow. Thanks a lot for the help !
