System Architecture

Hey Happy Faces..

Welcome again to my Blog!!!

This time you people would be taught on Systems Architecture by reading the conversation between my Grand Father, Grand Mother and I.

I know what is running on your mind now,  How your grand father can learn System Architecture???

You can understand by reading the following conversation.

Grand Pa: My love, Still I  have a doubt that How computers and Internet are working, And your father used to tell me that to the post of evolution of ERP, His pressure has been reduced.

Grand Ma: Ya My dear, His work has been reduced to 60% after coming ERP.. What is ERP?? He never told us about that, at least you tell us about those technologies.

Me: Oh!!!! Great.. Grand Pa and Grand Ma, you two have so much interest to get to know about the technologies.

Me: I am surprised!! I though that at this age you don't even heard about these terms.

Grand Pa : My love, Bases of these technologies innovated during my school days. I loved to know about that but I couldn't get any access to know about these.

Me: Yes, I can understand. I will tell you grand pa.

Grand Pa: Thank you my love.

Me: System Architecture is a structure to handle objects called Systems.
        A system is an aggregation of subsystems cooperating so that the system is able to deliver the     overarching functionality. System integration involves integrating existing components.

Grand Pa & Grand Ma: Hmmm ..

 Me: Now lets try to focus on Integrated Systems. To integrate system it requires skill.These skills are likely to include software and hardware engineering, interface protocols, and general problem solving skills.

Grand Ma:  My dear, which means your father has these skills right? I know he is very talented. You should also become like My son. Ok?

Me: Sure!! I grow along with technologies, I love that, That is why I am sharing my knowledge to you.

Me: Firstly I tell you about what is Tier? Means, each in a series of rows or levels of a structure placed one above the other. This architecture was innovated in 4 different times to integrate the systems and for fast & easy accessing purpose.

Grand Pa: My love, Thank god that you defined what is tier else I would have misunderstand it has Tyre.

Me, Grand Pa & Grand Ma: Laughs :-)!!

Me:
        1. Single tier- This ensures that the  data is separated from applications from the same physical hardware.

        2. Two Tier: This uses a GUI which makes it more interactive. It is a convenient graphics user interface. Local Area Network(LAN), servers, individual machines are the main components.

        3. Three Tier: Business Logic is kept centrally and Presentation Logic is kept locally. Application is separate from the Business Logic.

   

        4.  Multi Tier: Internet is in the form of WAN. Specialist software is not required at each client location. A 4-tier architecture allows an unlimited number of programs to run simultaneously, send information to one another, use different protocols to communicate, and interact concurrently. This allows for a much more powerful application, providing many different services to many different clients.

 Now let’s go a step ahead further.

     1. integrated Database Systems: Data consistency and no duplication of data is given priority.         

     2. Integrated ERP Enterprise Resource Planning. Enterprise resource planning  is a business management software—usually a suite of integrated applications—that a company can use to collect, store, manage and interpret data from many business activities

Grand Pa:  Great Innovations and advancement in the line of IT Technology.

Grand Ma: My dear, You are too good at explaining , Pls become Teacher in future.

Me: Grand Ma??? I want to become computer Engineer and To complete communications in IT field.

However, For your love and request, I will become a computer and Networking Teacher.

Grand Ma: Your grand Pa & I, are very great to learn from you, my dear. During your childhood days , I used to tell stories for you, but now your are telling me informative story.

Me: Oh I remember Grand Ma. It was great to think of that. To post lunch, Please tell me few stories.

My conversation ends here..

People I think that by this time you also come to know about system architecture.

Thank you so much for your patience to read. Happy Day!!

How puzzels can be used to write program?

Hello Programmer & Non-Programmer!!

Start( )
{
Printf(" Happy Evening!!" );

What you people think about HAPPINESS????????

Thinkkkk>>>>

Did U?? Before reading the following stupid sentences... do think...

Spending time with most loved ones ( Or )

Making others glad ( Or )

Doing your most favorite thing ( Or )

Listening to music ( Or )

By making yourself into land of serenity ( Or )

Anything which you feel like that makes you comfort & so on....

Peace is not happiness....

All these routine sounds are not happiness...

For me...

The Happiness is all about doing anything DESIRABLE & VALUABLE work ( Work means everything that happens BY and FOR you ) that leads to SATISFACTION..

This satisfaction is the breathing tool for HAPPINESS:-):-)!! 

This may be normal or silly for few people, But this is the way to see the image-less HAPPINESS..

Stay Happy:-)!! Means Work Hard to get the desired things done and do get satisfied with the result ..And strive for happiness..

Happiness is surrounded by Sorrows, Means face the struggles to taste the real happiness after success note..

Happy Life:-):-):-)...Alwayssss!!!
 
With Happy Note--- Rajasekar
