Implementing the classes, functions, models and Connecting to Database

[bjin02]

• Implement the Info, Post data class to model the data
  The class should include a repr method that can descripe the Post/Info data
  And a contains method to check if the Post data contains some words in Summary
• Use this class definition for database models in your program
  Process the raw data to model the Post data into instances of the classes
• Connect to the database and get Info and Post database tables data
  Set up Info and Post database tables in a database, and store the data instances in them.

Database table data with these columns in each:

Info

id
followed
likes
total_posts	title
url
ask_page_title
name

Post

id
date
summary
format
short_url
can_like
can_reply
type
info_id

• Post table has the external key to the Info table. We can make JOIN query to these tables

• Setup the DB connection code to Connect, Insert, Update and Query the tables
