Order Workflow Stored Procedures
This project requires Neo4j 3.2.x
This project uses maven, to build a jar-file with the procedure in this project, simply package the project with maven:
mvn clean package
This will produce a jar-file, target/workflow-1.0-SNAPSHOT.jar,
that can be copied to the plugin directory of your Neo4j instance.
cp target/workflow-1.0-SNAPSHOT.jar neo4j-enterprise-3.2.3/plugins/.
Edit your Neo4j/conf/neo4j.conf file by adding this line:
dbms.security.procedures.unrestricted=com.maxdemarzi.*
Restart your Neo4j Server.
Create the Schema by running this stored procedure:
CALL com.maxdemarzi.schema.generate
Create some test data:
CREATE (o:Order {id:'o1'})
CREATE (p1:Provider {name:'Provider One'})
CREATE (p2:Provider {name:'Provider Two'})
CREATE (w1:Work {id:'w1'})
CREATE (w2:Work {id:'w2'})
CREATE (t1:Task {id:'t1', requires:"(e1 & e2) | (e3 & !e4)"})
CREATE (t2:Task {id:'t2'})
CREATE (t3:Task {id:'t3'})
CREATE (e1:Event {id:'e1'})
CREATE (e4:Event {id:'e4'})
CREATE (o)-[:HAS_WORK]->(w1)
CREATE (o)-[:HAS_WORK]->(w2)
CREATE (p1)-[:PERFORMS]->(w1)
CREATE (p2)-[:PERFORMS]->(w2)
CREATE (w1)-[:HAS_TASK]->(t1)
CREATE (w2)-[:HAS_TASK]->(t2)
CREATE (w2)-[:HAS_TASK]->(t3)
CREATE (e1)-[:FIRST]->(o)
CREATE (e4)-[:PREVIOUS]->(e1)
See which tasks can be completed and their event dependencies:
