#FUNDAMENTAL SQL The most popular SQL-based databases include PostgreSQL, MySQL, Oracle, MS SQL Server, and SQLite.

Most databases store your data in a hidden-away part of your computer’s filesystem. You’d never interact with the data directly, only through the tools provided by the database engine. SQLite, instead, stores its data in a plain-text file. This makes it incredibly easy to move, rename, delete, or transfer the database.

###Experimenting with SQLite

• Firing up the Sqlite db:

  • In the terminal: sqlite3 example.sqlite3

• Creating a table in the terminal:

  attr_reader :equation

  def initialize(equation)
    @equation = equation
  end

  def answer
    calculate
  end

    @value = value
