Precision needed in the Graph Data Modeling course

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

Thank you

These courses are just perfect to be sure that you know what you are doing.
