数据库-什么是预订系统的良好数据库设计？

Question

I have a school task where I have to build a booking system for meetings for a (fictional) company that has to fulfill the requirements in this pdf: http://docdro.id/FmHngHe (its better for you to read it then me trying to explain the details, all you have to read is part 2 and half of part 3. Its not that much :) )

The problem I am facing right now is to create a proper database design for this project. I have a vague idea of how the design should look like. I know for example (approximately) what entity types I should have for this project but I am struggling in trying to figure out how all the tables should be connected. What should the relationships be like and what extra relationship tables do I need.

This is what I got so far:

But it feels like I am missing a big part of the puzzle here. It feels incomplete. I feel like there should be a whole lot more relationship tables in the design but then I will end up with over 10 tables which feels like a bit much for such a small project or am I doing this completely wrong?

I would like this to be a very simple design. Am I overcomplicating this?

Please help.

Thanks!

Answer 1

I would suggest, first of all, write all the requirements in one table. 1 row is the flat structure of all the requirements. Then start breaking it one by one. That 1 table structure should be having all the required columns. Then follow Normalization concepts of breaking 1 single table into multiple tables.
