Creating an associate table in power apps

(1) ShareShare

Posted on by CU-20080846-7 14

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:

    1. Define User Table: This table will store user details.

      • User Table Columns:
        • UserID (Primary Key)
        • UserName
        • Email
        • etc.

    2. Define Exam Table: This table will store exam details.

      • Exam Table Columns:
        • ExamID (Primary Key)
        • ExamName
        • Date
        • etc.

    3. 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)
