Course Introduction

In Database Management System (DBMS), we study the database which is organized and structured collection of data. DBMS is a software system which acts as intermediary between user or application and the data. It allows to navigate through the data and analyze the data. In this course, we are going to learn the core mechanism that holds the system together.

Goal

In this course, we are going to learn the essence of data base management system. Students are going to learn the following concepts.

  • Relational model
  • Entity-relational model
  • SQL
  • External, conceptual, physical levels of DMBS
  • Data definition language, Data manipulation language, query language
  • Data structures
  • Index
  • Transaction and Concurrency

Working Environment Setup

Step 1: Installing Jupiter Notebook

Gentle reminder that, jupyter notebook best works at Linux


Option 1: Installation via Anaconda

It is recommended that you install Jupyter Notebook via Anaconda

  1. Download & install Anaconda for Python here
  2. Run jupyter notebook to confirm that it is properly installed

If Anaconda doesn't have jupyter: you can try running

conda install jupyter


Option 2: Installation via pip

You can also install via the python package manager pip

  1. Make sure you have installed
    • python and pip
  2. Make sure pip is updated to its latest version
    pip install --user --upgrade pip
  3. Install Jupyter Notebook
    pip install --user --upgrade jupyter


Installing other kernels and versions of python

When you are using Python3 and want to switch to Python2 in the notebook,

python2 -m pip install ipykernel

python2 -m ipykernel install —user

After restarting the Jupyter, you can chose different kernel in Jupyter notebook.

Step 2: Installing Other Dependencies

Git

Git is a version control system which we use to store the various course material; you can download from here

  • you can download the course material from here
  • If you want the up-to-date version of the course material, checkout the course repository from the git by typing the following command

IPython-SQL

python-sql allows you to use SQL queries inside jupyter notebooks; install using pip

  • pip install --user --upgrade ipython-sql

other modules

you will be needing

  • markdown
  • numpy

Step 3: Getting Started

Getting the latest course materials

You can always access the latest course materials on the course website. You can download all at once and keep them synced by using git. To get started with this, run:

git clone https://github.com/resourceful/lecture_db YourDestination

Now you should have all the materials in Database; to get the latest version, run the following command in the repository.

git pull
