Query-Driven Data Modeling: Business-Focused Examples Needed

I guess this is more a question typical of a Business Analyst rather than a KG developer, but I am trying anyway: I am looking for hands-on examples for query-driven data modelling / knowledge graph design. I have found some very few examples in Denise Gosnell's "The Practitioner's Guide to Graph Data" (by the way an excellent book), but her examples start at a too graph-close level, making it hard to communicate them to the business side (who do not think in metrics, data points, verticals and edges immediately). I would be curious to see an example that starts with a purely business-oriented question, say "Which of my regional offices are similar to each other in terms of types of customers / types of projects they deliver?", breaking it down into ever more specific metrics and data points and finally a conceptual graph-oriented model of the corresponding query / queries. I would be very grateful for any tips for case descriptions or even templates.

    Veronika Haderlein-H酶gberg hello 馃憢! I鈥檓 so glad you are finding parts of my book to be helpful. I agree that an improvement would be to start with a business oriented question and break it down before going so heavy into the graph concepts. Have you started chapter 10? We cover the business concepts of recommendations and break it down into smaller questions. But, instead of businesses, we use movies. I鈥檓 going to be speaking at the KG conference. Maybe this would be a good topic to cover? I would love your input. Thank you!

    Additionally: For the business question above, I would recommend building up to it with the following sequence of smaller questions: Understanding recommendations with a sample of one: 1. What is my set of regional offices? Pick one office. 2. Which customers visit that office? Pick one customer. 3. Which other offices does that customer visit, excluding the original office? Done: this is a set of offices similar to the first office according to one customer. Now, let鈥檚 expand the same idea to use all offices and all customers: 1. What is my set of regional offices? Put them in a set. 2. Which customers visit any of these offices? Put them in another set. 3. Which other offices are visited by this set of customers, excluding the original set of offices? Done: this is a set of offices similar to the regional offices according to their customers. You can repeat this line of thinking for other concepts like projects, deliveries, etc. I hope this helps! Thank you for the question.

    Thanks again, Denise G., this is very useful! And I will definitly dive into chapter 10 馃檪 I hope to be able to join you for your presentation at the KGC . Very much looking forward to hearing more about the practicalities of query-driven design.
