1. First, understand the story.

Do you understand the story completely? If not, talk to the product owner to clarify your understanding.

Is the story a logically cohesive grouping of functionality? If not, can it be broken into multiple stories?

Do the points assigned make sense given your current level of understanding of the story? If not, can it be broken into multiple stories?

#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:

require 'time'

class Gigasecond
  attr_reader :quantity

  IN_SECONDS = 1_000_000_000

  def initialize(quantity)
    @quantity = quantity
  end

require 'date'

# puts "What are you? #{ARGV} #{ARGV.class}"

# Called as in `ruby example2.rb 1977 10 30`
# birthdate = ARGV.map {|arg| arg.to_i }
birthdate = [ 1977, 10, 30 ]
# year, month, day = [ 1977, 10, 30 ]

# birth_in_seconds = Date.new(year,month,day).to_time.to_i
