图形数据建模（Neo4j）

Question

i am new to graph databases. I am having some issues while modeling data. I am working on site which contains information about books. I have categorized books in different categories like: arts, fiction etc. I ve generated a node for each category. Nodes of categories are unconnected with each other and that where the first issue comes. To solve this issue i am going to index a node called category and connect all my category nodes to it which leads me to the second issue of dense node or super node . Now tell me how to solve both these issues.

Answer 1

You should use labels. The idea of super nodes was for neo4j < 2.*

You can add a label BookCategory and when you want to return back all your bookCategoryNodes, just specify the label in the match query :

MATCH (n:BookCategory) RETURN n
