Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

#System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

##Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

	function Article(props) {
	return (
	<Container img={props.image}>
	<div className="imageContainer">
	<div className="image"></div>
	</div>
	<div className="description">
	<p className="title">{props.title}</p>
	<span>{props.meta}</span>
	</div>

	import React from 'react';
	import styled from 'styled-components';


	const Container = styled.div`
	display: flex;
	align-items: flex-start;
	padding: 8px;
	border-radius: 4px;
	box-shadow: 0 10px 20px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);

	{"abandoneze" : -2,
	"abandonat" : -2,
	"abandoneaza" : -2,
	"rapit" : -2,
	"rapire" : -2,
	"rapiri" : -2,
	"detesta" : -3,
	"detestat" : -3,
	"odioase" : -3,
	"uraste" : -3,

	'ACID (Atomicity, Consistency, Isolation, and Durability)'
	0 Atomicity: Either the task (or all tasks) within a transaction are performed or none of them are. This is the all-or-none principle. If one element of a transaction fails the entire transaction fails.
	0 Consistency: The transaction must meet all protocols or rules defined by the system at all times. The transaction does not violate those protocols and the database must remain in a consistent state at the beginning and end of a transaction; there are never any half-completed transactions.
	0 Isolation: No transaction has access to any other transaction that is in an intermediate or unfinished state. Thus, each transaction is independent unto itself. This is required for both performance and consistency of transactions within a database.
	0 Durability: Once the transaction is complete, it will persist as complete and cannot be undone; it will survive system failure, power loss and other types of system breakdowns.
