database design - Node in multiple linked list -


in our neo4j graph created serval linked list of top items specified category.

example:

top-50 week 2016-01 - mike posner - afrojack - willy william

at point created this:

 (node top 50 week 201601)-[first]->(node mike posner)-[next]->(node afrojack)-[next]->(node willy).

but next week, order changed willy, mike, afro. , end having multiple next relationships on each artist. traversal list slower.

any idea, how model in better way.

the answer @stdob-- more valid, doesn't scale well.

imagine want find artists ever been number 1 , how many times, you'll have match of them traversing relationships , filter on rank property. nightmare if have 1 million artists.

the idea of linkedlist fine, nodes in linkedlist can example rankitem node related artist.

(week1)-[:first]->(rankitem)<-[:has_ranking_positon]-(artist)

for previous question, can :

match (w:week)-[:first]->()<-[:has_ranking_position]-(artist) return artist, count(*) occurences

depending on queries you'll need do, makes sense have rankinglist rankitem connect also.

(ranking {v:1})-[:next]->(ranking {v:2})-[:next]->(.....

in case, rankingitem connect list

making things more performant questions :

based on artist, find me artists have common pattern of ranking history

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
