Hi Everyone,

I am trying to create an "association table" in dataverse

The premis goes like this

I have two seperate tables. one for users (given a unique user ID) and another one for exams (given an exam ID)

Now i need another table to link the users to the exams that they have earned please see example below:

I am not too sure how I would go about it as the user ID and exam ID will have to be repeated as a person can have multiple exams and an exam can be written by multiple people

Thank you in advance!

In Dataverse you can have a N:N relationship established between exam and user tables.

Hello

You will have to create a N:N manual between these two tables:

Creating an association table (also known as a junction table or linking table) is a common practice in database design to handle many-to-many relationships. In your case, you need a table that links users to exams. Here’s a step-by-step guide to accomplish this in Dataverse:

Define User Table: This table will store user details.
User Table Columns:
UserID (Primary Key)
UserName
Email
etc.
Define Exam Table: This table will store exam details.
Exam Table Columns:
ExamID (Primary Key)
ExamName
Date
etc.
Create Association Table: This table will link users to exams.
Association Table Columns:
AssociationID (Primary Key)
UserID (Foreign Key referencing UserID in User Table)
ExamID (Foreign Key referencing ExamID in Exam Table)
EarnedDate (Optional, if you want to record when the user earned the exam)
