The ALX-Holberton B&B sums up the implementation of my four months of studies at the ALX-Holberton School - the fullstack software engineering program. The goal of the project is to deploy a replica of the Airbnb Website using my server. The final version of this project will have:
1. A command interpreter to manipulate data without a visual interface, like a shell (for development and debugging)
2. A website (front-end) with static and dynamic functionalities
3. A comprehensive database to manage the backend functionalities
4. An API that provides a communication interface between the front and backend of the system.
5. General concepts in review
As you navigate this code base, it is great to note the following concepts, while completing this project;
The console was developed in Ubuntu 14.04LTS using python3 (version 3.4.3).
For further information on python version, and documentation visit python.org.
Knowledge in python3, how to use a command line interpreter, a computer with Ubuntu 14.04, python3 and pep8 style corrector.

Team project to build a clone of AirBnB.
The console is a command interpreter to manage objects abstraction between objects and how they are stored.
To see the fundamental background of the project visit the Wiki.
The console will perform the following tasks:
- create a new object
- retrive an object from a file
- do operations on objects
- destroy an object
All the classes are handled by the Storage engine in the FileStorage Class.
- Style guidelines:
All the development and testing was runned over an operating system Ubuntu 20.04 LTS using programming language Python 3.8.3. The editors used were VIM 8.1.2269, VSCode 1.6.1 and Atom 1.58.0 . Control version using Git 2.25.1.
