Using graph data stores and utilizing the related capabilities has become a trending topic in the Master Data Management (MDM) space. This opportunity was first examined 5 years ago here on the blog in the post Will Graph Databases become Common in MDM? It seems so.
Recently David Borean, Chief Data Science Officer at the disruptive MDM vendor AllSight, wrote the blog post The real reason why Master Data Management needs Graph. In here David confirms the common known understanding of that graph databases are superior compared to relational databases when it comes to handle relationships within master data. But David also brings up how graph databases can support multiple versions of the truth.
Several other vendors as Semarchy and Reltio are emphasizing on graph in MDM in their market messaging.
Aaron Zornes of The MDM Institute is another proponent of using graph technology within MDM as mentioned over at The Disruptive MDM Solutions blog in the post MDM Fact or Fiction: Who Knows?
What do you think: Will graph databases really brake through in MDM soon? Will it be as stand alone graph technology (as for example from neo4j) or embedded in MDM vendor portfolios?

Good timing Henrik! In fact today (at this very moment!) Semarchy CEO Salah Kamel is giving a talk about MDM and graph at the Enterprise Data Warehouse show in San Diego:

Absolutely, I also remember that Salah wrote a very well thought blog post on the subject about a year ago https://blog.semarchy.com/does-mdm-need-graph
