==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
# Download & install Anaconda for Python [https://www.anaconda.com/download here]
# Run <code>jupyter notebook</code> to confirm that it is properly installed

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

<code>conda install jupyter</code>

==== Option 2: Installation via <code>pip</code> ====
You can also install via the python package manager <code>pip</code>
# Make sure you have installed
#* <code>python</code> and <code>pip</code>
# Make sure <code>pip</code> is updated to its latest version
#; <code>pip install --user --upgrade pip</code>
# Install Jupyter Notebook
#; <code>pip install --user --upgrade jupyter</code>

==== Installing other kernels and versions of python ====
When you are using Python3 and want to switch to Python2 in the notebook,

<code>
python2 -m pip install ipykernel

python2 -m ipykernel install —user
</code>

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 [https://git-scm.com/downloads here]

* you can download the course material from [https://github.com/resourceful/lecture_db here]
* If you want the up-to-date version of the course material, checkout the course repository from the <code>git</code> by typing the following command
** <code> git clone https://github.com/resourceful/lecture_db YourDestination </code>

==== IPython-SQL ====
<code>python-sql</code> allows you to use SQL queries inside jupyter notebooks; install using pip
* <code>pip install --user --upgrade ipython-sql</code>

==== other modules ====
you will be needing
* markdown
* numpy
* pandas

=== 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:

<code> git clone https://github.com/resourceful/lecture_db YourDestination </code>

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

<code>git pull</code>

==== To read the notebook ====
In the directory where the relevant course materials are, run:

<code>jupyter notebook</code>

== Course Credit ==
Much of the materials of this lecture is based on CS145 of Stanford.
