Ruby Design Patterns

This repo shows some examples of design patterns in ruby language. This is only for learning purposes and may contain failures or code that is not the best. This is intentionally to simplify the comprehension of the patterns.

Introduction

I have been thinking about a global scenario in where I could show most part of examples. I have decided to apply examples to seller envoironment. But it is easy, we only are going to have invoices with seller or remitent info and line_concepts. this diagram will show you about it:

graph LR
Invoice[Invoice] -- has one --> SellerInfo[SellerInfo]
Invoice[Invoice] -- has one --> BuyerInfo[BuyerInfo]
Invoice[Invoice] -- has many --> LineConcept[LineConcept]
