# 06 Project: Critter Chronologer
**Final Project**
{%youtube 7kzI6JBc_Cc%}

For the final project in this course, we’ll be creating the Critter Chronologer, a software as a service application that provides a scheduling interface for small businesses that take care of animals. We’ll allow users to create schedules that associate pets, owners, and employees for a pet-care event on a specified date.

This application will store all the relevant data in a MySQL Database and allow a predefined controller layer to send and receive updates. You’ll have to design all the data objects on the back end and create the data and service layers to update and retrieve them.
