E-R and relational model help needed

Hi,

I'm new here so I'm sorry if this is the wrong place to post this.

I'm not too sure on how to represent a model as a client-server system.

The model I'm designing requires a user to select optional modules from a given list.
Any help or guidance would be really appreciated. Thank you for your time.

try creating the ERD both with this as an entity and without it

leave this bit to the very end after you have completed the ERD
