There is an organization that makes Events from time to time. People came to Event to join workshops. As usual, Event takes one day. There are several meeting rooms in Event area. Each workshop could go several times a day, in different meeting rooms, at different time. For example, there are 3 workshops in coming Event – “PHP best practices”, “Symfony CMF for beginners” and “Mastering Symfony 2”. “PHP best practices” goes in room “Elephant”: at 9:00, at 11:00, at 13:00; and also it goes in room “Blue sky” at 10:00 and at 12:00. Goal of this application is to build front-end part. People go to site, see available workshops in coming Events.
