How to link entities

Some background


What is understood with linking entities?


Linking entities is a fundamental aspect to ensure the accuracy, traceability, and quality of data in
accident and incident reports. Linking entities helps create a cohesive view of complex events by
connecting various elements such as separation, aircraft, events… Linking entities involves creating
relationships between different data elements within an accident or incident report.

  • Improved Data Relationships and Context
  • Enhanced Data Consistency and Accuracy
  • Easier Data Analysis and Reporting
  • Supports Comprehensive Investigations
  • Facilitates Data Sharing and Interoperability


From within the Taxonomy browser, it can be identified for which entities relationships can be
created.

1. Open the taxonomy browser

2. Select an entity and open the “Child Entities” tab and filter on “Relation is Linked”

Example 1

In the first example, Aircraft can be liked to

  • Airspace
  • Events
  • Runway
  •  Sector
  • Dangerous Goods


Example 2

In the second example, Separation Aircraft can be linked to

  • Aircraft

How to create relationships between entities

Creating relationships or links between entities is done when a document is in edit mode.

There is a prerequisite, the entities for which a relationship is to be created need to be on the view
used for editing the document.

When a link between entities is possible, then the link option becomes visible


Clicking on the link will show which relationships are possible

In the example above, the Separation Aircraft entity can be linked to the aircraft as defined in the
occurrence. It is possible to have both aircraft selected.
In the example below, the aircraft N267JB can be linked to different entities

Good practice


When linking entities, it’s essential to use clear and consistent naming conventions. This can be
effectively achieved with the “pattern composer” when creating views, as it enables systematic and
meaningful naming. A well-designed naming pattern makes entities easier to identify, enhances
readability, and simplifies future maintenance across systems.


This to avoid having difficulties to what entity another entity is linked as seen below

When clicking on the related link in the tree view, E2 navigates to the appropriate entity
