Need Help in creating an application to manage limited resources across multiple user

  
Dear community, 
I am very new to outsystems and have no programming background. I wanted to work towards developing an application that would allow room bookings by many users who also have their own availability schedule, as well as booking of the students to attend the differnt classes that attend the lessons in this room. i hope it would also notify clashes when the student is required in both classes and propose alternative slots.

currently i am trying to follow the first tutorial for making a telephone directory.

I am open to any help or guidance that can be provided.

Thanks everyone.
