This page contains *example* scenarios for demonstrating Neo4j "Perspectives" and "Scenes" which are used to explore data in a graph database from the perspective of a particular user.  Perspectives focus the view by selecting specific nodes and relationships, while scenes allow for visualising the data interactively.


## Scenario 1: Programme Leader Perspective

**Goal**: Enable a programme leader to gain insights into their programme's structure, student engagement, and potential areas for improvement.

### Perspective:

**Nodes**:

* Programme (central node)
* Module
* Student
* Activity
* Room
* Staff

**Relationships**:

* Programme <-[:BELONGS_TO]- Module
* Module <-[:BELONGS_TO]- Activity
* Student -[:REGISTERED_ON]-> Programme
* Student -[:ATTENDS]-> Activity
* Student-[:ENROLLED_ON]-> Module
* Activity -[:OCCUPIES]-> Room
* Staff -[:TEACHES]-> Activity

### Scenes:

**Programme Overview**: Visualise the entire programme structure, showcasing modules, their connections, and associated activities. Highlight popular and less popular modules based on student enrolment.

**Student Engagement**: Focus on a specific module and visualise student attendance patterns. Identify students with low attendance and potential at-risk students.

**Resource Allocation**: Visualise room utilisation across the programme's activities. Identify potential scheduling conflicts or underutilised spaces.

**Staff Workload**: Analyse the distribution of teaching workload among staff members within the programme.


### Example Cypher Queries:

```{cypher}{scroll-cypher}
//Programme Structure:

MATCH (p:programme {name: 'Computer Science'})<-[:BELONGS_TO]-(m:module)
RETURN p, m


//Student Attendance:

MATCH (m:module {name: 'Data Structures'})-[:BELONGS_TO]->(p:programme)<-[:REGISTERED_ON]-(s:student)-[:ATTENDS]->(a:Activity)
RETURN m, s, a


//Room Utilisation:

MATCH (p:programme)<-[:BELONGS_TO]-(m:module)<-[:BELONGS_TO]-(a:activity)-[:OCCUPIES]->(r:room)
RETURN p, m, a, r

Staff Workload:

MATCH (p:programme)<-[:BELONGS_TO]-(m:module)<-[:BELONGS_TO]-(a:activity)<-[:TEACHES]-(s:staff)
RETURN p, m, a, s
```

## Scenario 2: Module Leader Perspective

**Goal**: Provide a module leader with insights into their module's scheduling, student performance, and room allocation.

### Perspective:

**Nodes**:

* Module (central node)
* Activity
* Student
* Room
* Assessment

**Relationships**:

* module <-[:BELONGS_TO]- activity
* student -[:ATTENDS]-> activity
* activity -[:OCCUPIES]-> room
* student -[:HAS_RESULT_FOR]-> assessment
* module -[:HAS_ASSESSMENT]-> assessment


### Scenes:

* **Module Schedule**: Visualise the module's activities, their timeslots, and associated rooms. Highlight potential scheduling conflicts or overlaps.
* **Student Performance**: Focus on a specific assessment and visualise student results. Identify students who may need additional support.
* **Room Suitability**: Analyse the rooms used for the module's activities and their capacities. Identify potential issues with room size or suitability.



## Scenario 3: Administrator Perspective (Room Usage)

**Goal**: Ability to analyse room usage, identify underutilised spaces, and optimise room allocation.

### Perspective:

**Nodes**:

* Room (central node)
* Activity
* Module
* Programme

**Relationships**:

* activity -[:OCCUPIES]-> room
* module <-[:BELONGS_TO]- activity
* programme <-[:BELONGS_TO]- module

### Scenes:

* **Room Utilization Overview**: Visualise all rooms and their occupancy levels across different time periods. Highlight rooms with low utilisation or frequent conflicts.
* **Room Activity Breakdown**: Focus on a specific room and visualise the activities scheduled there. Identify peak usage times and potential scheduling issues.
* **Programme Room Usage**: Analyse room usage by different programmes. Identify programmes with high room demands or potential conflicts.
