likaiguo / GRAPHS FOR HR ANALYTICS

Last active August 29, 2015 14:14 — forked from rvanbruggen/GRAPHS FOR HR ANALYTICS

	This gist explains how a graph database can help for HR analytics. There are two files included:
	- load the data.cql: this file contains the cypher statements that load the data into neo4j
	- query the data.cql: this file has some sample queries that serve to demonstrate some of the concepts.
	Hope this is useful.
