User Story:

AS A business owner

I WANT to be able to view and manage the departments, roles, and employees in my company

SO THAT I can organize and plan my business

Goals of this Project:

GIVEN a command-line application that accepts user input

WHEN I start the application

THEN I am presented with the following options: view all departments, view all roles, view all employees, add a department, add a role, add an employee, and update an employee role

WHEN I choose to view all departments

THEN I am presented with a formatted table showing department names and department ids

WHEN I choose to view all roles

THEN I am presented with the job title, role id, the department that role belongs to, and the salary for that role

WHEN I choose to view all employees

THEN I am presented with a formatted table showing employee data, including employee ids, first names, last names, job titles, departments, salaries, and managers that the employees report to

WHEN I choose to add a department

THEN I am prompted to enter the name of the department and that department is added to the database

WHEN I choose to add a role

THEN I am prompted to enter the name, salary, and department for the role and that role is added to the database

WHEN I choose to add an employee

THEN I am prompted to enter the employee’s first name, last name, role, and manager, and that employee is added to the database

WHEN I choose to update an employee role

THEN I am prompted to select an employee to update and their new role and this information is updated in the database

Installation:

This project is run in Node.js. You will need 3 npm packages; inquirer(version8.2.4), mysql2, and console.table(allows tables to be seen in the console).

What I Learned:

The main thing I learned was how to write SQL query statements. The most complicated one was in the function viewEmployees. This required me to figure out how to combine different tables and make them viewer friendly.

I believe moving forward, I see the value in OVM and using Sequelize to avoid some of te very long query statements.
