Overview Goal Why build a graph database for the offshore wind farm domain? Content What do we put into the database? How do we structure the content in the database? Does everything fit easily in this structure? Practical setup What software and hardware do we use? Querying How do we add and extract data? Conclusions What is different from what we expected? What are our plans for the future?
