OpenBOM Data Modeling Demo – Part 2

Today, I’d like to continue my articles about OpenBOM data management. In my previous article, I was converting reference-instance fundamentals. Please check it here. 

You can check also OpenBOM Data Management fundamentals article, which speaks about three important elements of OpenBOM data management model:

1- Data management architecture 

2- Reference-instance model

3- Parent-chield relationships 

To speak about Parent-Child relationships, I will use a simple model of a Skateboard. A very simple model contains 2 assemblies Skateboard and Axle Assembly. Each assembly has its parts. 

The parent-child relationships model creates relationships between assemblies.  OpenBOM organizes relationships automatically based on Part Numbers. The parent-child relationships model works in parallel with the reference-instance model. Parent-child relationships are modeled in the Bill of Materials. The Reference-instance model is supported by relationships between Catalogs and BOMs. 

Here is a picture that explains parent-child relationships. 

Here is the video of my OpenBOM Data Management – Part 2.

Conclusion 

OpenBOM parent-child relationship is a fundamental element of the product information data model. OpenBOM creates automatic relationships based on part numbers and by doing so supports multi-level and flattened BOMs in OpenBOM.
