# Deading with Relations

Work in Progress (06/02/2020)

This section is still a work in progress. It will be updated soon.

heliosRX currently focuses more on the "O" and "M" not so much the "R" on "ORM". This section will therefor elaborate a little bit on the following topics:

  • Explain what relationships mean with NoSQL
  • Explain what "relations management" means in the context of heliosRX / Firebase
  • Give examples how relationships are managed in heliosRX / Firebase

# Example 1: Nested data (1:N)

  • /project/{projecId}
  • /project/{projecId}/task/{taskId}

# Example 2: Parallel data (1:1)

  • /project/{projecId}/task/{taskId}
  • /project/{projecId}/task_details/{taskId}

# Example 3: Reference (N:M)

  • /user/{userId}
  • /user/{userId}/project_list/{projectId} -> Project Reference

# Example 4: Reverse reference (N:M)

  • /project/{projectId}/members/{userId} -> User Reference

# Example 5: Relationship (N:M)

  • /user/{userId}/friends/{userId} = true
