Precision needed in the Graph Data Modeling course

[tard_gabriel]

Hello again

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?

Thank you

Hello @tard.gabriel,

This definitely needs to be clarified. I will modify the course. A data item and a data object are the same thing. I will clarify that and use the same terminology for both. In a query data items will include node labels, relationship types, and of course properties.

Thanks for bringing this to our attention.

Elaine
