I am looking for an expert in data modelling. We have a database design which stores multiple entities in a many-to-many relationship setting. There is a table with multiple users and there is a table with multiple campaigns. A user can vote on multiple campaigns. A campaign can exist of multiple votes by different user. Each user can only vote once every campaign (just for your information). A simplified view of the database is attached in an Excel file. Because of Excel's limit to support many-to-many relationships, junction tables need to be created. I would like advice on how to design the junction tables and make the attached data-model work with one-to-many and many-to-one.

Hallo Gezien het vlagje naast uw profiel vermoed ik dat u ook Nederlands spreekt wat ik dus ook zal doen om de communicatie iets vlotter te laten verlopen. Vanuit uw beschrijving veronderstel ik dat u voornamelijk een EER model wilt (met eventueel een SQL script wat geen probleem is). Ik heb in het verleden al vaker databanken ontwikkeld en denk dat ik deze opdracht wel goed aankan. Met vriendelijke groeten Wouter
