Dedicated to sports and love!!!
This is one awesome semester that is happening to me. The semester started with a late christmas party with friends at kolkata. four full days of fun. Then the new yr nite with friends at campus and bonfire. Then a dance party at Shibani with Alex Gupta as a guest and friends as sponsors.Then came cricket. Me and almost all my friends got selected into the hostel cricket team and we are playing the intra IIT cricket tournament for the last 1 month almost. and for the first time in the history of my hall since its inseption in 1962, my hall reached the quarterfinal of the tournament. Then Spring fest. The same fest that i attended 4 years ago and had good memories of which. This one also was amazing. Met kailash kher and suchitra pillai. Then came kshitiz. I am not sure if i would be in campus to witness complete kshitiz but one this is for sure, last 1 month was rocking. Ohh...i did not talk about love...i have started watching romantic love stories again. apart from that there is not much love.. barring the one sided love that i always do....and yeah i am spending a lot of time in my room these days...may be socializing less..and few significant people are not calling these days..out of sight is definitely out of mind..just hoping for better tomorrows....

System Architecture
Having worked for an ERP project on Oracle applications, I already had some basic idea of the System Architecture of the system. But to improve my existing knowledge and discuss the core concepts I called my friend Ankit who happens to be a DBA and works for the same client for whom I worked.
Me: hi Ankit.. How are you?
Ankit;: I am fine. How are things going at your end?
Me: I am doing great. Studies and assignments are keeping me busy these days.
Me: Hey, I called you because we had a class today on Systems Architecture and I wanted to discuss few things with you.
Ankit: Yeah, Sure. Tell me.
Me: I will start with my understanding of the topic. System architecture consists of Data and Applications. Data is a collection of information related to an organization or person. While an application is something which is used to represent this data. Applications acts like a window using which one can look into the data and modify or update it.
Ankit: Yes, you are correct. But then there is a lot to add to what you just said. I mean when you say data and application are they segregated?
Me: That’s right. Logically they are two different entities. But they might be present on the same physical location. For example, we store data in document format .doc in our computer and MS word application helps us read and process this data which is stored on the same computer. And to add to all this we have this different tiered System Architecture to implement complex systems.
Ankit: Yes correct. Single tier architecture in which data and application are on the same system, For example, our laptop or desktop. Second is a two tier architecture in which data and application are on two different system and they are connected by TCP/IP protocols. The machine having application is called client and the machine that contains data is called server.
Me: Correct. Now, along with these two we have a three tier architecture where in we have a business application layer between the data and the user interface. The forth variant is Multitier structure where in Internet is used. This is the most used and highly robust structure used these days because of the business going global.
Ankit: Hmmm. In fact if you might remember, even we use this multi tiered structure for the ERP that we use at GE.
Me: Yeah, I remember. Oracle applications is implemented with multi tier structure at GE. Users access the application through internet from different geographies which in turn connects to the database and provides information to the user.
Ankit: Yes, you are correct. In fact we also have implemented a structure where in the data is stored in the same database while the access rights are different for different users.
Me: Yes. I remember. As a purchasing super user I had the access to all the sourcing related data while my counterpart in the finance department could access only finance data and not sourcing one. This method not only saves the cost for the organization but also improved the data management and system administration.
Ankit: Hmmm I guess you have covered most of the general aspects of the System Architecture..
Me: Yes. Even I think so. But then if you get some news or some latest changes happening in the industry, so keep me updated.
Ankit: Yeah sure my friend.
Me: See you. Ciao Ciao
Ankit: Bye

My life at present..
I can define this period as the golden period of my life where in I am living the multiple lives. I am living life of a young teen ager whose mornings start in a rush with thoughts running as to what he is going to wear to the class, what he will do to have fun and what he will do to make the someone special more happier. I am living the life of a 25 year old mature man who plans and aspires to be a successful manager and will do whatever it takes to achieve his dream. I am living the life of philosopher who writes his own stories, stories which are connected to his life, stories which describe what he wants to do and make him happy. I am in that stage of life where every moment throws a new challenge, is as fresh as it can be and is worth living. I always thought that my undergraduate college life was the best I had but I must say that last six months have been awesome. These six months came with a lot of sad and happy moments and most importantly I had friends with me all the time to take care of both. Lots of pre-notions were shunned, the most important being that you cannot make a close friend at the age of 25. You can actually and they might turn out to the best ones. This duration showed me times when I felt lost; when I felt that I was lonely. But then there were ample number of activities to compensate all the loneliness. I just hope that the coming two years remain the same or turn out to be even better.
Human beings are social animals and they have achieved many heights not just because of their intelligence but because they had this unique attribute of living together, helping each other and sharing joys and sorrows.I believe that it is the society in general and family, friends and elders in particular who can help me the most in achieving my dreams. My postgraduate education from one of the most reputed colleges of the country will be the first step in the direction. The IIT education system and the amazing faculty of VGSOM will help me acquire the much needed and deserved knowledge and wisdom that will help me excel in all the future endeavors of mine. But above all this I think that most important thing that will help me in future is my experience of life; my experience of meeting and recognizing good and bad people, of joys and sorrows, of caring and sharing, of helping and getting helped, of pampering and being pampered, and of life and death.
