Sinatra App

Introduction

To practice everything we've learned over the last couple days, your task is to build a full blown Sinatra app from scratch. It should have full CRUD for a single model with a RESTful controller and corresponding views.

What can you make? You're welcome to be creative, but if you need some ideas:

• An app to help organize your fancy scotch collection
• An app for a library to know which books are currently lent out

#Brokerage App - Requirements

Create your own brokerage and map your associations to respect the following hierarchy:

• Your brokerage can have many clients
• A client can have many stocks
• Many clients can have the same stocks so you need to know everyone's holdings (e.g. Bob owns 15 Google Stocks but Joe owns 23 of them)
