I was reading the Data Accessibility part of the Graph Data Modelling Core principles
I'm confuse with these sentences:
For each query, how much work must Neo4j do to evaluate if the traversal represents a “good” path or a “bad” one?
you can estimate performance by checking how “accessible” the data items are
For each data object, how much work must Neo4j do to evaluate if this is a “good” path or a “bad” one?
What are exactly a data item?
What's the difference between a data item and a data object?
For each query or for each data object?
