title: Advice needed for a small web application's architecture/implementation
body: <p>I was asked to build a website where a company's employees (around 20) could login and fill in their working schedules for a present and past (if needed) month. Employees should ofcourse only be able to see their own schedules, but the manager should have the privilege to access every schedule.
  I have little experience in web development therefore an advice is needed. I have already created a PHP/MySql login page. Now what? How do I go about it? 
  Just some architectural or implementational(if you will) guidance would be really appreciated. </p>
