Editing Neo4j (section)

== Neo4j Graph Database Setup ==

=== Setup ===
* Created an EC2 instance named '''neo4j''' to host the Neo4j graph database.
* Installed Docker on the EC2 instance to simplify Neo4j deployment.
* Used Docker to pull and run the official Neo4j image.

=== How It Works ===
* The Neo4j database is accessible through:
  * '''HTTP''': Port 7474 (for the Neo4j browser interface).
  * '''Bolt Protocol''': Port 7687 (for applications connecting to Neo4j).
* Authentication is set up with the user `neo4j` and password `testpassword`.
* Data modelling and queries can be managed via the Neo4j browser or other tools.

=== How to Access ===
* Open your browser and go to:
  <pre>
  http://<EC2-IP>:7474
  </pre>
* Login with the credentials:
  * Username: '''neo4j'''
  * Password: '''testpassword'''
* Run queries using Cypher to create, manage, and explore the graph database.

=== Purpose ===
* The Neo4j instance is set up for building and exploring graph-based data models.
* Enables tracing and visualisation of relationships within the dataset.

=== Relationships ===
Currently, the graph database is set up to track the following relationships:

* '''ASSIGNED_TO''':
  * Represents the assignment of a user to clients

* '''ENROLLED_TO''':
  * Tracks the enrolment of a client to a GP

* '''INTERACTED_WITH''':
  * Captures face-to-face interactions between navigators and clients.
  * Includes properties like `Notes`, `ContactMethod`, and `ContactType` to provide additional context about the interaction.

* '''RELATED_TO''':
  * Client is related to another client


=== TODO ===
* Implement ETL process
