Relational Data Model
In the previous blog post, we covered Data Modeling. We have seen that data modeling is really important before jumping into predictive modeling. In this article, we will cover the Relational Data Model (RDM). Let's start from the very basics, relational means anything which is linked with some other thing. This link is called "Relationship". In RDM or RM there are major three types of relationship cardinalities (also called Multiplicities or Cardianalities): 1. One to one 2. One to many 3. Many to many We can understand these with the help of a few simple examples; One to one: One department has one manager. One to many: One class has many students. Many to many: Many teachers can teach many students. Okay, so we have got an abstract overview of the term " Relational ", now the next thing is " Data ", data covers everything, anything... And finally, " Model " means something in the form of a template, design, a kind of blueprint. To store...

Ethical Dilemma : Software One
Consider a situation : You are a software engineer. And you can write any kind of code, from one extreme to another. From the code of virtue to the code of disaster. You are working in the international level, world famous and the top most software company. Your Monthly salary is more than the salary of every officer in the world. Means: You are living a luxurious life, you are healthy, wealthy and wise. You have no tension, no problem in your life. You are living near to perfect life.

How? Read this book Why? Because you are to become a software engineer and programming is the basic need, the food for thought of a software engineer especially a programmer software engineer... But... This is too long So what? You have to read it! May be it contains something that is beneficial to you..
Github : Part 1 : Introduction
Have you ever gone through the problem of version control while working on some coding project in a group? Did you find it difficult to share code with each member of a group? Yes? Then this blog post is for you... Problem.. Back in days, people used to write code but they found it difficult to share and control the progress of their code in contact with each other. Say You are in Pakistan while your friend is in New York and both of you are working on some project involving coding and programming. With time to time you need to send some portion of your code to your friend to test it for further progress. After completion of your project you need to send the whole source code to your supervisor living in India. You are using email and Google drive for sending source codes, but this is not feasible but tedious as your friend need to download it then by modifying it on his own computer, send it back to you. This wastes a lot of time and is prone to errors. Solutio...
Pintos : Series : Part 1 : Installation
PintOS is an Operating system, but this is not a complete OS. There are many kernel level functions implemented but we need to modify it to implement it correctly. So, if you are taking OS course or interested in Operating Systems then you can follow my PintOS Series. As installation of PintOS is the most important and tedious task, so we need to do it first! Actually I have learnt about the installation steps from various sites, I will share their links side by side. What I grasped from there, I will compose it into this post. I know you might be thinking if the installation steps are already available on-line, then why am I writing them for you? The reason for this is that, when I installed PintOS, I found a lot of problems initially but then it worked. So, what I understood from my experience and from the sites, I will share that. I believe that if learning is done through mutual cooperation, then this will benefit everyone . So, let's learn together.... First Mist...

Hollow Diamond
Drawing different shapes with the help of coding is quite enjoyable and interesting. Mostly the first semester students of software engineering encounter with this. so, let us learn, how to draw a hollow diamond using python? First of all declare variables: Diamond consists of two cones , upper cone with pointed top and lower cone with pointed bottom . so let us write the code for the upper cone, but the cone must be hollow: The resultant of this code is as under: Now, write the code for lower hollow cone: The output for this code is: Now, run both the codes simultaneously, and the output is: the reason for this output: This is one of the possibilities of writing code, to get this output. There might be other ways of doing the same task. Keep finding and trying different ways of coding. And do remember: Programming language doesn't matter but logic matters . So, work mainly on logic building .
for my semester project..
