+# Neo4j funnel analysis
 
-### Description 
+This Neo4j based project does a funnel analysis for a E-Commerce website. It is designed to serve as a template for further development projects.  Feel encouraged to fork and update this repo!
 
+## Data Model
+
+![enter image description here](https://i.imgur.com/a3k6Vl2.png)
+
+### Nodes with properties 
+
+* `User { id: string, timestamp: timestamp, device: string, gender: string }`
+* `Entry { page: string}`
+
+### Relationships with properties
+
+* `(:User)-[:VISITED {count: string}]->(:Page)`
+
+
+## Users and Pages
+
+### Load some fake data 
+
+If you're running the app locally, you might want to tweak without having a robust community of users.
+In the `/datasets` directory, note that there are files named  `users.csv, search.csv, home.csv, checkout.csv, payment_confirm.csv`.
+These files contains some pseudo-randomly generated values.
+
+Move `users.csv` into the `import` directory of your database either by dragging and dropping or using
+
+Set your  `NEO4J_HOME`  variable:  
+```bash 
+export NEO4J_HOME=/path/to/neo4j-community
+``` 
+Copy files : 
+ ```bash 
+ cp datasets/users.csv $NEO4J_HOME/import/users.csv
+ ```
+ Copy every file contained in the `datasets` directory by the above command 
+
+Assuming your database is running, paste the following queries into the Neo4j browser:
+
+```
+// Assert that the USER nodes are unique by it's ID
+CREATE CONSTRAINT ON (u:User) ASSERT u.user_id IS UNIQUE;
+
+// Assert that the ENTRY nodes are unique by it's page name
+CREATE CONSTRAINT ON (e:Entry) ASSERT e.page IS UNIQUE;
+``` 
+```
+USING PERIODIC COMMIT
+LOAD CSV WITH HEADERS 
+FROM 'file:///your/location/user.csv' AS line
+WITH DISTINCT line , datetime(line.`date`).epochMillis as date
+
+CREATE (u:User { id: toInteger(line.`user_id`) })
+SET u.date = toInteger(date),
+    u.device = line.`device`,
+    u.gender = line.`gender`
+```
+```
+// Create page node with diffrent page properties 
+CREATE (:Entry { page : 'search_page'})
+CREATE (:Entry { page : 'checkout_page'})
+CREATE (:Entry { page : 'home_page'})
+CREATE (:Entry { page : 'payment_confirmation_page'})
+```
+```
+// Load search page entry and create relationships 
+USING PERIODIC COMMIT
+LOAD CSV WITH HEADERS 
+FROM 'file:///search.csv' AS line
+WITH line
+
+MATCH (u:User { id : toInteger(line.`user_id`)}), (e:Entry { page : 'search_page'})
+MERGE (u)-[r:VISITED]->(e)
+    ON MATCH SET r.visited_count = r.visited_count + 1
+    ON CREATE SET r.visited_count = 1
+```
+```
+// Create user and checkout page relationship
+USING PERIODIC COMMIT
+LOAD CSV WITH HEADERS 
+FROM 'file:///checkout.csv' AS line
+WITH line
+
+MATCH (u:User { id : toInteger(line.`user_id`)}), (e:Entry { page : 'checkout_page'})
+MERGE (u)-[r:VISITED]->(e)
+    ON MATCH SET r.visited_count = r.visited_count + 1
+    ON CREATE SET r.visited_count = 1
+```
+```
+// Create user and home page relationship
+USING PERIODIC COMMIT
+LOAD CSV WITH HEADERS 
+FROM 'file:///home.csv' AS line
+WITH DISTINCT line
+
+MATCH (u:User { id : toInteger(line.`user_id`)}), (e:Entry { page : 'home_page'})
+MERGE (u)-[r:VISITED]->(e)
+    ON MATCH SET r.visited_count = r.visited_count + 1
+    ON CREATE SET r.visited_count = 1
+```
+
+```
+// Create user and payment confirmation page relationship
+USING PERIODIC COMMIT
+LOAD CSV WITH HEADERS 
+FROM 'file:///payment_confirm.csv' AS line
+WITH line
+
+MATCH (u:User { id : toInteger(line.`user_id`)}), (e:Entry { page : 'payment_confirmation_page'})
+MERGE (u)-[r:VISITED]->(e)
+    ON MATCH SET r.visited_count = r.visited_count + 1
+    ON CREATE SET r.visited_count = 1
+```
