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
